WHAT ARE LASER TREATMENT PROCESSES?

Detailed eye examination should be performed to determine suitability for laser treatment. During the examination, visual acuity and glasses numbers should be determined, corneal topography should be taken, biomicroscopic examination should be performed and finally eye pressure should be measured.

The presence of systemic diseases such as age, diabetes, goiter, and high blood pressure should be questioned in detail, and Wavefront or Topolazer advanced examinations should be performed as needed.

For laser treatment, the topographic map of the corneal layer of the eye is determined in detail with a topography device and the thickness map of the cornea is obtained. Corneal thickness is as important a parameter as the eye number in choosing the surgical method to be applied.

After dropping a drop that dilates the pupils and waiting for about 30 minutes, the eye numbers are determined again and a detailed eye examination (retinal vessel and nerve layer) is performed. If there are risky areas such as thinning, tears, holes in the retina, these areas are protected with the argon laser method. Argon laser application may require to delay , excimer laser treatment for 3 weeks, but it does not prevent treatment. It provides a more secure application.
The data obtained as a result of all these examinations and analyzes, which take approximately 2-3 hours, are evaluated by the refractive surgeons and the most appropriate treatment method is decided. Laser treatment may not be performed on the same day as the pupils dilate due to the drip examination and it is necessary to wait for a while to return to normal. An appointment for surgery can be given minimum one day after.

There is no harm for the patient who will have laser treatment to eat on the day of treatment.

The patient must only pay attention for;

• Not wearing eye make-up,
• Not using use perfume,
• Not using blood thinners.

When the patient enters the laser room, they are asked to lie on their back on the bed. A sterile drape is covered over his eye, and then his eyelids are opened with a specially manufactured tool to prevent him from blinking during the treatment. Laser treatment takes about 4-5 minutes for each eye, the patient won’t feel pain or hurt. It is very important that the patient is comfortable throughout the treatment and follows the doctor’s instructions. After the treatment is over, the patient is removed from the laser room without bandaging his eyes.

The patient, whose laser treatment is completed, is kept waiting for about half an hour and is taken for a control examination. The patient can leave our hospital after this control. First day; It is normal to have blurred vision and stinging, burning and watering in the eyes for 3-4 hours. It is necessary to pay attention to the use of medication as recommended by the doctor. If a headache is felt after laser, a pain reliever that does not have blood thinning properties can be taken. We do not recommend driving a car and going to work on the day of surgery. Avoid being in a dusty environment, the treated eye should not be rubbed, scratched, touched, washed or bathed during the first 24 hours. In the first days, care should be taken not to get soap and shampoo in the eyes. The next day of the operation, there are no side effects left that will limit social and work life. The next day of the operation, during the check-up, If wrinkles are detected in the transparent area on the surface of the eye or if there is a reaction under the flap (valve), it may be necessary to wash the bottom of the flap. An artificial tear drop recommended by the doctor should be used for approximately 3 – 6 months after the operation.

SMILE LASER / RELEX

For Which Patients is Smile Laser Treatment Applied?

Smile laser treatment is one of the personalized superficial laser treatments that we usually apply to eyes with thin corneas and not very high myopia and astigmatism. As a result of a detailed examination, Smile Laser treatment can be applied to people whose eye structure is found suitable for surgery by the doctor.

It is a suitable treatment method for athletes and occupational groups who are at risk of being exposed to impact and pressure.

How is Relex Smile Laser Treatment Applied?

With Zeiss Visumax Femtosecond technology, a thin lenticule (disc-shaped tissue) is created in a single step within the front layer of the eye (cornea). There is no need to cut any flap (valve). Since no flap is created, corneal biomechanics is less affected.

What is the Difference of Smile Laser?

SMILE (Small Incision Lenticule Extraction) and No-Touch Laser technologies; in recent years, it has attracted attention as a treatment method for myopia and astigmatism. With these technologies, successful results are obtained in myopia and astigmatism problems and less dry eye problems occur after laser.

Why Smile Laser?

• Treatment up to -10 in myopia and -5 in astigmatism
• Protection in corneal biomechanics
• Compatibility with thin corneal structure
• Incisionless operation with closed surgical technique
• One-stage surgery
• Safe recovery

What Changes in Your Life with Smile Laser?

• You can easily see your watch and your face in the mirror.
• You can get a natural look and vision without glasses and lenses.
• You can provide comfort and higher success in your sports activities.
• You are less affected by climatic events such as wind and rain.
• You can improve your quality of life by getting rid of the restrictions you experience in your daily activities because you cannot see clearly.

FAQ

Frequently Asked Questions for Smile Laser

The cornea should be at least 500 microns thick. In some special cases, the Smile method can be considered with a thickness of 490 microns.

It takes about 10-15 minutes. Recovery after smile laser happens quickly. The next day after the operation, the patient can return to work life, and sports such as walking and jogging can be started. Water sports can be started in 1 week, impact sports such as karate and kick boxing can be started in 1-2 weeks.

This method can be applied in the treatment of myopia and astigmatism refractive errors. For the treatment of hyperopia, alternative methods recommended by the doctor are recommended as a result of the tests performed.

Blurred vision may last about 2-3 hours after the operation. Regularly using the drops recommended by the doctor after the treatment is very important for you to have a healthy healing process.

NO-TOUCH SMART LASER

No-Touch Smart Laser - Personalized, Non-Contact Laser Theraphy

With No-Touch Smart Laser treatment, myopia and astigmatism treatment is done without touching the eye.

Which Patients Can Be Applied to No-Touch Smart Laser Treatment?

No-touch Smart laser treatment is one of the personalized superficial laser treatments that we usually apply to eyes with thin corneas and not very high myopia and astigmatism. As a result of a detailed examination, No-Touch Smart Laser treatment can be applied to people whose eye structure is found suitable for surgery by the doctor.

As a result of detailed examinations and tests, people whose eye structure is found suitable for surgery by the doctor can be treated with laser.

How is No-Touch Smart Laser Treatment Applied?

No-Touch Smart Laser treatment process is a painless method that is performed only under drop anesthesia, as in other laser treatment methods. Laser surgery is performed by direct contact of the beams emanating from the laser device to the eye. Unlike the Lasik method, there is no need to remove a thin membrane as in the Lasik method. Therefore, it can be preferred especially in those who do sports with heavy-risk trauma. The application is made on both eyes in the same session. Laser surgery is applied for the treatment of astigmatism and myopia. After the operation, a protective lens is also placed on the eyes. After the patient is discharged, conditions such as stinging, redness, discomfort from the light and blurry vision of small prints on the television may be experienced for 36 hours. The patient is called for control the next day and on the third day. After the controls, the patient can continue his daily life from where he left off.

What is the Difference of No-Touch Smart?

No touch Smart laser treatment is a personalized non-contact laser that is performed using the wavefront principle and iris identification technology. With iris recognition, the rotation of the eye in its own axis can be calculated; this method enables us to treat astigmatism in the most accurate axis.

Why No-Touch Smart Laser?

• Provides superior protection in corneal biomechanics.
• Both eyes are operated in one step.
• Rapid recovery is seen after the operation.
• It provides conformity in thin corneal structure.
• It can be applied to myopia and astigmatism patients.

iLASIK (iDesign Wavefront)

What is i-Lasik Laser?

Around the world, 80% of the average people have a refractive error.

Refractive surgery, which has been applied since 1980 and gives the most reliable results in the treatment of refractive errors, is the laser method. With the developing technology, refractive errors such as myopia (difficulty in far vision), hyperopia (difficulty in near vision), astigmatism (blurring in the image) can be treated with laser.

The aim of laser treatment is to increase the quality of life of people and to enable them to have a more comfortable life. Today, the most widely used treatment method in the world for the treatment of refractive errors is the I-LASIK (Laser Assisted insitu Keratomilluesis) method. This method is personal and is performed in accordance with the eye structure of the patient as a result of detailed examination and examinations.

Who is i-Lasik Laser Applied to?

• For those over the age of 18.
• For those with myopia up to 10 degrees, hyperopia 6 and astigmatism up to 4 degrees.
• For those whose corneal layer is thick enough.
• Those who do not have systematic diseases such as diabetes, rheumatism.

As a result of the preliminary examination and examinations, I-Lasik laser treatment can be applied to people whose eye structure is found suitable for surgery by the physician.

How is i-Lasik Surgery Performed?

In the i-Lasik application, the entire process is planned specifically for the patient with wavefront and idesign technology, and even the smallest defects can be corrected with the combination of the eye recognition system.

With the use of femtosecond laser, bladeless incisions are possible, thus increasing the success of the treatment.

Wavefront

By sending a light beam to the eye, the program is determined by evaluating the image obtained in the retina layer.

It is a preferred method to avoid scattering, scattering and shadowing around the light after laser, especially in patients with night vision problems or large pupils.

After the evaluation with special Wavefront analyzers, the operation decision is made.

iDesign Wavefront

In the first stage, a personal vision profile is prepared with Wavescan technology.

Then, a corneal incision is made with a femtosecond without the use of a knife. Now the vision can be corrected within the framework of the iLASIK application.

The information reflected from the light sent to the eye is detected by a special camera. This information is sent to the laser and the planned treatment is applied. One of the reasons why personalized treatment (Advanced CustomVue™) is preferred is that three-dimensional visual mapping can be obtained in Wavefront aberometer.

In laser treatment, it is very important that the device shoots at the planned point of the eye.

Therefore, there must be a digital locking system (eye tracker) between the device and the eye. In Wavefront treatment, measurements are performed while sitting, while the operation is performed in a lying position. In this position, a small rotational movement may occur in the eye. The iris layer of the person is detected by the laser device and can follow the movements in the eye around its own axis.

Femtosecond Laser (Intralase)

What is Femtosecond Laser?

Femtosecond Laser; It is a new laser technology used in the treatment of refractive errors such as myopia, hyperopia and astigmatism with refractive surgery.

Femtosecond enables the creation of a thin incision in the cornea, which is the most important stage that affects the success of laser surgery under computer control, at the desired level and without a blade with laser beams. Creating the incision with laser light instead of a blade minimizes the risk. The femtosecond laser increases the success of the surgery by providing the opportunity to create a personalized incision.

Due to the characteristics of the cornea, the femtosecond incision method in the cornea is especially recommended by our doctors for some patients.

With Blade Laser;

• Unplanned surgical results, flap tears

• High risk in people with thin corneal structure

• Inability to apply treatment to people with a high eye number

• Higher risk of dry eye

With Bladeless Femtosecond Laser;

• Opportunity to create flaps in the planned thickness for those with thin corneal structure.

• Opportunity to have laser in people with high eye number.

• Lower risk of post-operative dry eye.

What is PRK?

PRK (Photorefractive Keratectomy) is a treatment method that aims to correct these defects of patients with refractive errors such as myopia, hyperopia and astigmatism.

What is LASEK?

Lasek is based on the principle of removing the epithelial tissue in the eye with the help of alcohol. After the laser is applied, the epithelium spreads back to its place. Although safe results are obtained with these two surface methods, patients may experience burning, stinging and watering for 2-3 days. On average, vision becomes clear in 1 week-10 days.

What are the Features of PRK/LASEK Methods?

• It is recommended for some eye structures whose corneal thickness is not suitable for Lasik, although the eye degree is small (in myopia and astigmatism up to 3 degrees).

• The eye is anesthetized with only drops, as in the Lasik method.

• The patient does not feel pain during the operation.

• Contact lenses are inserted in order for the epithelium to recover and to protect the eye, and it is removed under the control of a doctor 3-4 days after the operation.

What are the Points to Consider Before PRK Laser Treatment?

Before Treatment

There is no harm in the patient’s eating on the day of treatment.

The patient is just;

• Should not wear eye make-up,
• Should not use perfume,
• Should not drink blood thinners.
• It is recommended that patients using contact lenses stop using their lenses 1 week before PRK examination and surgery if they are using soft lenses and 2 weeks before using hard lenses.

What are the Advantages of PRK Surgery?

• No scar is formed because a corneal flap (membrane) is not removed.
• Patients who do not want to leave a scar often prefer it.
• Since the corneal flap (membrane) is not removed, there is no deterioration in the natural structure of the cornea.
• Those who have PRK laser surgery do not feel pain or pain and eye pressure does not increase since vacuum is not used during the operation.

What Should Be Considered After PRK Laser Treatment?

The patient, whose laser treatment is completed, is kept waiting for about half an hour and is taken for a control examination. The patient can leave our hospital after this control. First day; It is normal to have blurred vision and stinging, burning and watering in the eyes for 3-4 hours. It is necessary to pay attention to the use of medication as recommended by the doctor. If a headache is felt after laser, a pain reliever that does not have blood thinning properties can be taken. We do not recommend driving a car and going to work on the day of surgery. Avoid being in a dusty environment, the treated eye should not be rubbed, scratched, touched, washed or bathed during the first 24 hours. In the first days, care should be taken not to get soap and shampoo in the eyes. The next day of the operation, there are no side effects that will limit social and business life. If wrinkles are detected in the transparent area on the surface of the eye during the doctor’s control the next day or if there is a reaction under the flap (valve), it may be necessary to wash the bottom of the flap. An artificial tear drop recommended by the doctor should be used for approximately 3 – 6 months after the operation.

What is Myopia?

Myopia is the problem of seeing far away clearly. When the eyepiece cannot focus, it has difficulty seeing distant objects and landmarks, but can clearly see objects that are close. Myopia, which is one of the most common visual defects, usually manifests itself in school age and may increase until adulthood.

Myopia is a common vision condition in which you can see objects near you clearly, but see distant objects blurry. It occurs when the shape of your eye causes light rays to bend (refraction) incorrectly, focusing images in front of your retina instead of on the retina.

How Does Myopia Occur?

Myopia can usually occur due to genetic reasons. However, environmental factors are effective in increasing myopia. Myopia, which usually manifests itself between the ages of 6 and 13 in children, may increase depending on the growth of the body, this is a normal situation.

Why Does Myopia Occur?

Myopia occurs when the shape of the eye causes light rays to bend (refraction) incorrectly, focusing images in front of your retina instead of on the retina. It is possible for you to inherit the ability to be nearsighted and then develop it through environmental factors. For example, long-term work in small-screen vehicles can improve myopia.

How Myopia See?

Myopia usually occurs in childhood. Typically it can worsen with age. Images appear unclear because the light coming into your eyes is not focused correctly. This situation can be thought of as a misdirected spotlight. If you shine a spotlight on the wrong spot in the distance, you won’t be able to see the right object clearly. People with myopia also experience a similar vision problem.

Myopia Degrees

Mild myopia is 0 D to -1.5 D, moderate -1.5 D to -6.0 D, and high myopia is -6.0 D or more. People with pathological myopia experience more than -8.0 D, but vision-related threats in diseases such as retinal, cataract, and glaucoma can also occur in people with moderate to high myopia. One of the most important causes of myopia and astigmatism is keratoconus disease.

What are the Symptoms of Myopia?

• Myopia Symptoms in Children
• To squint his eyes,
• Frequent rubbing of his eyes,
• squinting,
• Not recognizing objects at a certain distance,
• Routine eye examination in children is very important for early diagnosis and treatment.
• Myopia Symptoms in Adults
• Eye strain and accompanying headache,
• Difficulty in seeing while driving at night,
• The need to squint or partially close the eyelids,
• Blurred vision after a certain distance.

How Is Myopia Treated?

Myopia can be treated by the use of glasses or contact lenses in children and adults, depending on the degree of treatment. Other methods recommended for those who do not prefer to use glasses or contact lenses are, colloquially, myopic eye drawing, that is, laser treatment and intraocular lens treatment. With these methods, you can correct your distant vision problem to a certain extent and continue your life without the need for glasses and lenses.

According to the eye structure and suitability of people who do not want to use glasses and lenses, laser or intraocular lens treatment can be applied. After the treatment, the person does not need glasses or contact lenses. The most commonly used procedures for the treatment of myopia are Photorefractive keratectomy, lasik and smile.

Myopic Eye Drawing Procedure and Myopic Surgery

Photorefractive keratectomy, also called PRK, this surgery uses a laser to sculpt the middle layer of your cornea. This flattens the curve of the cornea and allows light rays to focus closer to or on your retina.

LASIK

This is the most common surgery for myopia. The surgeon uses a laser or other instrument to create a thin flap in the top layer of your cornea. They shape the cornea with another laser and move the flap back into place.

SMILE

Smile laser treatment is one of the personalized superficial laser treatments that we usually apply to eyes with thin corneas and not very high myopia and astigmatism. As a result of a detailed examination, Smile Laser treatment can be applied to people whose eye structure is found suitable for surgery by the doctor.

How Is Myopia Test Done?

Myopia can be diagnosed during a general eye exam. Myopia is usually diagnosed in childhood, but may develop in adults as a result of environmental influences, stress, or diabetes. Myopia test is performed by placing different lenses in front of your eyes during the examination. You are first asked to look at a
light or read the letters in a painting. Special eye drops may be given to check eye health so that the back of the eye is examined more clearly. Depending on the result, your doctor can write a prescription.

Which lens is used in myopia? / Which lens corrects myopia?

Intraocular lens (ICL): Using a microscopic incision, a lens made of a soft, polymeric material is implanted in your eye between your natural lens and iris. It provides better vision by helping the light to be refracted on the retina.

The most commonly used methods in laser treatment are: SMILE, LASIK, Femtosecond LASIK, i-LASIK and PRK applications.

FAQ

Frequently Asked Questions for Myopia

The main cause of myopia progression is an increase in the axial length of the eye. Many factors can contribute to this: Wearing glasses all day every day can potentially cause worsening of myopia. If a child has low myopia, glasses should be worn only for activities such as watching TV or playing sports.

Concave lenses are used to correct myopia. With these lenses, the rays coming into the eye are refracted and they provide a clear image on the retina.

In normal vision, the image is sharply focused on the retina. In myopia, the focus is in front of the retina, causing distant objects to appear blurry. Myopia is a common vision condition in which you can see objects near you clearly but distant objects are blurred.

It is a temporary nearsightedness condition caused by relaxation of the nearsighted focus muscle of the pseudomyopic eye. In some children, this muscle does not relax in distant gaze and causes instant myopia. This condition occurs when a child uses their eyes to focus too much on something; Even if they look far away, their eyes continue to focus. Therefore, the child's vision resembles myopia. In optometry this indicates myopia, but is not permanent.

In most cases, the pseudo-nearsighted state occurs in children from the age of six to adolescence. It is less common after this age. In adults, this condition is very rare. Because the vision mechanism, which is very common in children, weakens with age. The main treatment for parents in adjusting their child's behavior is to reduce close-up focused activities and increase outdoor play activities. If you are unsure
whether your child is nearsighted, take him to an ophthalmologist who specializes in children's eye diseases. The ophthalmologist will make an accurate diagnosis by using eye drops that temporarily paralyze the muscles that focus on the eye. The ophthalmologist will check the patient's refractive power to avoid near vision. If false myopia is suspected, the doctor will detect this situation with a detailed examination and direct it for treatment.

Astigmatism is a condition in which the cornea has an abnormal curvature that can create two foci to point to two different points. This also causes near and far objects to appear blurry. Astigmatism can be combined with eyestrain or farsightedness. Astigmatism is a condition that can be seen in childhood as well as in adulthood.

People with refractive errors should have their eyes checked regularly. Only in this way, the detection and treatment of refractive errors can be achieved.

What is Hyperopia (Nearsightedness)?

Hypermetropia is the condition of not being able to see near clearly as a result of the anteroposterior diameter of the eye being shorter than normal. The difference from the normal seeing eye is that when the cornea is flatter or shorter than normal (less refraction than normal), diverging from objects close to the eye, the diverging rays focus on a virtual point behind the retina. This incoming image becomes blurred on the retina and the patient cannot see the near clearly.

What Causes Hyperopia?

Hyperopia, which usually occurs with advancing age, can also develop congenitally. However, it may increase with advancing age, due to the progressive decrease in accommodation power with age. In addition, genetic factors play an effective role in the formation of this condition, which is a visual defect.

What are the Symptoms of Hyperopia?

• Shifting of letters or lines while reading.

• Eye and headaches in people who read for a long time.

• Seeing letters as intertwined in texts.

• Eyes getting tired quickly when looking up close.

• Near’s inability to see clearly

How Is Hypermetropia Treated?

The most common treatment method for refractive errors such as myopia, hyperopia and astigmatism is to use glasses. Eyeglass lenses for people with near vision problems are produced using thin-sided -convex- lenses that focus the light on the retina and increase the refractive power of the eye.

Contact lenses with the same optical properties can also be used to correct refractive errors. Another treatment method used in addition to glasses and contact lenses is laser or intraocular lens surgery.

What Are the Degrees of Hyperopia?

Generally, babies are born with hyperopia. Their grades decrease over time until the age of 18. There is no significant change after the age of 18. However, hypermetropes who can see distance clearly without glasses at a young age may need glasses for distance vision after the age of 40.

How is the Hyperopia Test Performed?

During the general eye examination, the necessary tests are performed and the refractive errors in the eye are examined. The test is performed with an ophthalmological examination. In the examination to be made, glasses of different properties are used, and in this way, the quality of vision of the person is measured between distances. With the examination to be made, the degrees of refractive errors in the eye can be calculated.

What are the methods used in the treatment of hyperopia other than glasses and lenses?

Intraocular lens therapy is one of the most recommended methods by physicians in the treatment of near vision impairment. Thanks to this method, patients can continue their lives without the need for glasses. Another method recommended for treatment is laser therapy. There is no 100% zero number guarantee after laser treatment, but about 90 of 100 people who have laser for nearsightedness can see fully without glasses or contact lenses.

Is Hyperopia Corrected With Glasses?

The most commonly used method for refractive errors is treatment with glasses. However, degrees cannot be permanently reduced with glasses or contact lenses. Therefore, patients may prefer laser or surgical methods for a complete treatment.

FAQ

Frequently Asked Questions for Hyperopia

This condition, which occurs as a result of a refractive error in the eye, is called nearsightedness. A person without myopia does not have a problem with farsightedness.

When glasses and contact lenses recommended for refractive errors are not used for a long time, focusing problems, difficulties in seeing objects and eye/headache complaints may occur.

The cornea, located in the frontmost layer of the eye, has the task of protecting the eye from external factors and refracting light and light correctly. A properly structured cornea refracts light and transmits it to the retina, that is, to the retina at the back of the eye. The transmitted images allow us to see clearly. In the eye with refractive error, since there are some irregularities in the shape of the cornea, it cannot refract the incoming light correctly and causes the image to be transmitted to the retina as blurred. A person with hyperopia and astigmatism cannot see clearly both near and far. Sees objects as elongated and scattered. This leads to distorted vision or blurred vision that is not clear.

Vision problems depending on the degree experienced in the eye can be easily corrected with glasses or contact lenses. Glasses and lenses provide clear near vision, but do not reduce degrees. As a surgical method, laser and lens operations can be applied for the complete treatment of degrees. With the surgical methods to be performed, the degrees of visual defect can be permanently corrected.

The duration of use of glasses in near vision impairment may vary for the patient. It will be beneficial for the patient to ask questions about the use of glasses and the intervals at which glasses should be worn under the control of the doctor.

A special type of lens is used in the prepared glasses, and thanks to this lens, the image falls exactly to the appropriate area on the retina, so that the patient can see the near clearly.

Hyperopia is caused by focusing the image behind the retina. This causes the near vision to be blurred. The reason why the image is blurry is due to the short anterior-posterior length of the eye, and more rarely, the less refractive power of the cornea or the lens of the eye.

People with latent hyperopia can see both far and near well if their numbers are not too high. For this reason, it will be understood after detailed examinations to be made. Generally, the most obvious complaints in people are eye pain, tired eyes, twitching and tearing eyes. These symptoms occur in activities that require more focus of the eye, such as knitting, looking at the computer, reading a book. In order to be protected from eye problems and to provide early diagnosis and treatment of eye diseases that may occur, do not neglect to have a regular eye examination once a year and to protect your eye health.

What is Astigmatism?

The cornea, located in the frontmost layer of the eye, has the task of protecting the eye from external factors and refracting light correctly. A properly structured cornea refracts light and transmits it to the retina, that is, to the retina at the back of the eye. The transmitted images allow us to see clearly.
In the eye with refractive error, since there are some irregularities in the shape of the cornea, it cannot refract the incoming light correctly and causes the image to be transmitted to the retina as blurred. It is a condition in which the rays coming into the eye cannot focus on the retina.

What Causes Astigmatism?

Refractive errors may occur as a result of genetic origin, congenital or diseases that can cause changes in the corneal layer. Another effective reason for this formation is that it may occur after a blow to the eye or an eye operation. One of the most important causes is keratoconus disease.

How Does Astigmatism See?

The person cannot see clearly both near and far. Sees objects as elongated and scattered. This leads to distorted vision or blurred vision that is not clear.

What Are the Symptoms of Astigmatism?

Although the symptoms differ from person to person, the most obvious complaints of people with visual impairment are usually blurry or shadowy vision at far or near distance.

The most common symptoms are;

• Blurred vision
• Scattered or scattered vision of lights
• Difficulty seeing while driving at night
• Eye fatigue after prolonged reading or focusing on something
• Squinting
• Eye itching
• Headache
• Shadowed vision

It is in the form. Since these symptoms make daily life difficult, an eye examination should be done for treatment if symptoms are experienced. Some symptoms may also be due to other health or vision problems. Therefore, do not neglect to consult an ophthalmologist to understand the cause of the problem.

What Are the Types of Astigmatism?

It divides itself into two groups. Visual impairment can also be categorized according to other accompanying refractive errors.
Myopia → astigmatism (astigmatism and nearsightedness problem) and Hyperopia → astigmatism (astigmatism and nearsightedness problem)

In regular astigmatism, the image is formed as two lines perpendicular to each other in two separate planes, while in irregular astigmatism, we see that there are many focusing lines instead of two perpendicular meridians, so irregular blurred visual acuity is severely reduced. It cannot be corrected with glasses.

How Is Astigmatism Test Done?

An autorefractometry (otoref) device is used for the test and a series of evaluations are made by the doctor. Diagnosis can be provided after the tests and evaluations made during the general eye examination.

Is Astigmatism Passable? How Is Astigmatism Treated?

Refractive errors such as astigmatism, myopia and hyperopia do not go away on their own. The eye condition must be evaluated and treated.

How is Astigmatism Treated?

Diagnosis of refractive errors can be determined by a general eye examination and treated with glasses or contact lenses prescribed by the doctor. Glasses or contact lenses do not reduce eye grades.
For a complete treatment, refractive surgery (Laser or Intraocular lens) or intraocular lens treatment may be recommended based on the suitability of the eye. For severe cases, doctors can usually recommend refractive surgery. With this type of surgery, lasers or small blades are used to reshape the cornea for permanent improvement.

Astigmatism Eye Drawing Procedure (Laser Treatment)

Three commonly used surgical types for treatment are SMILE, No Touch, LASIK, i-LASIK, and PRK applications.

There is no 100% zero number guarantee after laser operation, but approximately 95 out of 100 people who have laser for eye disorders can achieve full vision without glasses or contact lenses.

Frequently Asked Questions for Astigmatism

A special lens is used for people with astigmatism. The glasses used have a curved form to compensate for deformities in the cornea and to allow the person to see more clearly.
People who are above a certain degree (1.00-4.00) may experience problems such as headache and eye strain when they do not wear glasses for a long time. For this reason, it is important to use glasses at intervals recommended by the doctor in order to avoid complaints.

Astigmatism is a condition in which the cornea has an abnormal curvature that creates two focal points, pointing to two different points. This also causes near and far objects to appear blurry. Astigmatism can be combined with myopia. In this case, the distance does not appear clear and at the same time diffuse vision can be experienced.

When astigmatism and hyperopia combine, clarity soon disappears and blurred vision is experienced. Astigmatism shows its effect both near and far. This affects the person's daily life negatively. Detailed eye examination (drop examination) is required for the detection and treatment of hyperopia and astigmatism.

If it is not treated after it occurs, it is possible to progress. People with visual impairment should have regular eye examinations and monitor their eye health.

Headache is among the main complaints of the patients. This is because the images are not clear and there is a constant focus problem.

After diagnosis, it can be corrected by treatment with glasses, lenses or surgical methods.

Determination is made with a series of tests applied during the general eye examination. However, people who think they have this eye problem can check the symptoms in the 'Symptoms of Astigmatism' section. However, considering that it may occur without symptoms in some cases, an eye examination should be performed for a complete control.
