The cornea should be smooth and in the same curve on each axis. The fact that the cornea is more or less curved on a certain axis reveals the astigmatism defect. The image is not clear either far or soon, and the person sees things shaded.

E- Presbiyopi
It is the problem of not being able to see the relatives clearly, which starts after the age of 40 and occurs when the lens of the eye loses its elasticity under natural conditions. Unlike myopia, hyperopia and astigmatism, laser treatment is not possible.

The first step for a healthy and happy life…

Seeing is one of the most important factors that connect people to life. Therefore, regular eye examination is one of the most important steps to be taken for a healthy life. And it should be remembered that vision defects and diseases in the eyes can only be revealed by the ophthalmologist. An adult over 40 years old, whether wearing glasses or not, has to be examined once a year, even if they have no complaints. In children, this period can be every 6 months according to the doctor's suggestion, or even more often in some special cases. In a child who has no complaints, the 3rd year is ideal for first eye control.

Eye examination at Ada Hospital is performed meticulously and in great detail by the latest technological devices and an expert staff.

Ada Hospital

With the methods and technical devices applied in the Ada Hospital EYE CENTER, there is no need to wait for the cataract to mature for the eye to be operated. There is a high increase in the vision of the patients after the operation.

The essence of the operation is to remove the intensified lens from the eye and replace it with a new one. This lens called "intraocular lens" is permanent in the eye. It performs all the functions that the old lens does and is not felt by the patient. Two different methods are used to insert the intraocular lens:

Sutured and FAKO cataract surgery.

- Stitched Cataract Surgery
When using this technique, cataracts are expected to mature. It is stitched and stitches are removed some time after surgery. In this technique, the anatomical structure of the eye is weakened due to discontinuation, astigmatism may occur in the eye due to suturing, and it takes a while for vision to improve.

Cataract Surgery with FAKO (phaco mistification technique)
In this technique, the eye is entered through a small incision and the surgery is completed without stitches. Therefore, it is known as "seamless" or "laser" cataract surgery among the people. Delay in cataract surgery can even cause irreversible blindness. Thanks to FAKO, there is no need to wait for the cataract to mature for surgery.

Latest technology in cataracts…

In FAKO cataract surgery, there is no general or local anesthesia, except in special cases. The patient is prepared for the operation by putting only eye drops. After these drops placed 4-5 times, surgery may begin.

1 stage :

A drop of numbing is applied to the patient's eye 4-5 times. The region where the cornea, the transparent part of the eye, and the sclera forming the white part, is the place where the first incision is made in cataract surgery. The eye is reached through a special incision of approximately 3 mm. A jelly-like substance with the property of protecting eye tissues is filled into the eye from this incision. This substance provides safe working in the eye. Behind the iris, the colored part of the eye, is the lens (lens) of the eye (tissue called cataract when intersected). Cataracts are contained in a membrane. With the help of a cystotome tool, a round window is opened on the front of the membrane of the cataract.

Stage 2:

This membrane, which opens a window in the middle, is separated from the nucleus (nucleus) and shell (cortex) of the cataract by using liquid. With a special injector, the liquid that is given to the back of the membrane separates the membrane from other parts. Thus, the cataract becomes free within its own membrane.

Stage 3:

Cataract removal begins. During the process, a tool called FAKO is used briefly. This instrument uses ultrasonic power, i.e. sound wave power. This instrument, with a diameter of 2.7 mm, absorbs the cataract, absorbs them, and fills the discharged area with a fluid close to nature.

Stage 4:

In hard cataracts, the crushing of the nucleus is performed with the help of a second tool. The hard cataract is broken into smaller pieces, making it easier to clean.

Stage 5:

After the nucleus, which is a big part of cataract, is cleaned, the cortex is cleaned. This tissue is a kind of inner shell that adheres to the inner surface of the membrane. The natural membrane of the cataract becomes an empty clean bag.

Stage 6:

The intraocular eye is cleaned from cataracts. It is filled with jelly material for a safe operation. This substance fills the membrane that the cataract empties.

Stage 7:

It is time to replace the artificial intraocular lens with the natural lens (cataract) removed. This artificial lens made of a special material can be folded because it is soft. The artificial lens is folded with special systems and inserted into the eye through the incision prepared as 3 mm and then placed inside the membrane of the natural lens. The operation is completed without stitches.

In cataract surgeries performed at Ada Hospital EYE CENTER, phacoemulsification (FAKO) technique, also known as 'seamless' or 'laser' cataract surgery, is used among the people.


It takes 15-20 minutes, is done with a special microscope, the patient does not feel anything.
It is made from a small incision gap of 3.5 mm, that is, the integrity of the eye is not impaired.
Vision after surgery becomes much clearer than classical surgery.
Faster recovery is provided after the operation.


Myopia (not seeing far), hyperopia (not seeing nearby) and astigmatism (not seeing clearly) are caused by abnormal changes in the size and shape of the eye. Due to this deformity, the light refracted in the cornea and lens does not fall directly on the retina. These refractive errors in the eye can be corrected using glasses and contact lenses as well as with the Excimer Laser and LASIK method.


Our eyes are parallel to each other while looking directly across. The disruption of the parallelism is called strabismus.

Why it occurs?

How pregnancy passes, whether birth is problematic, child's development, illnesses, remittance or eye diseases can be risk factors for strabismus.

Strabismus in Children

Strabismus usually occurs in childhood. Some of the strabismus, especially in infants, is false slip. A false shift is a misleading appearance caused by the structure of the eyelids and eyeballs, or the irregularity of one of the optical axes. In order to fully clarify this situation, an eye examination must be performed.

As a result of negligence caused by lack of information, our children may encounter problems that are very difficult to treat at advanced ages. Two of the most important of these problems are SHAKLING and EYE BREAKING, which occur especially at a young age and can be successfully treated in case of early diagnosis.

The eyes of children, who cannot be diagnosed early and are not treated, are doomed to see a lifetime low in addition to aesthetic problem. Therefore, every child with strabismus should be taken to the ophthalmologist without waiting for a certain age.

When Is Surgery Necessary?

Congenital shifts are those that do not require glasses, and require early surgery (6 months - 1 year). The majority of the shifts occur around the age of 2-3 and can usually be fully corrected with glasses. Surgical treatment is required for slips that do not improve even with glasses on.

What is Amblyopia and How Is It Treated?

The most important problem in childhood shifts is eye laziness, which usually occurs due to a single eye shift. Eye laziness, in its simplest definition, is an eye's low vision. As a result of the fact that the image is not clear, the vision center in the brain cannot fully perform its function. The earlier the treatment is started, the better the chance of success. Because there is no cure for lazy eye after 7-8 years old. In treatment, the well-sighted eye is closed at certain times and the lazy eye is operated. Surgery has no place in the treatment of lazy eye.

· Strabismus and Treatment in Adult Ages

Strabismus that occurs in adulthood may occur in the nerves that govern eye movements for various reasons (trauma, diabetes, cardiovascular diseases, hypertension, various infections, tumors or poisoning). First of all, cause-oriented treatment should be done. In addition to the use of glasses in the treatment of strabismus, orthopedic treatment, closure treatment, medical treatment and surgical treatment with various drops can be applied with special tools.

Strabismus Surgery

Strabismus surgeries are mostly performed under general anesthesia. The basic principle of the operations is based on decreasing or increasing the strength of the muscles adhering to the eyeball or changing their places.

At Ada Hospital EYE CENTER; With strabismus, early diagnosis and treatment can prevent eye laziness and provide 3-dimensional vision.

(retinal detachments - bleeding due to sugar and hypertension)

The retina is the back wall of the eye, made up of millions of vision cells. The visual cells that make up the retina deliver nerve fibers to the visual nerve to transmit images to the brain. Therefore, a healthy retina is the main element of our sense of vision.

Retinal diseases; retinal detachments (tears), retinal bleeding due to diabetes and hypertension, intraocular foreign bodies, intraocular inflammation and congenital cataract.

Retinal Detachments (tears)

Retinal detachment is the detachment of the retina layer of the eye for various reasons. Retinal tears, on the other hand, occur as a result of tearing in the retina layer, especially at weak points. There are several reasons. While retinal tears can cause retinal detachment, patients especially complain of lightning strikes and bird wing flapping. This is an important clue. Apply to the ophthalmologist immediately. Because only good results can be obtained with early intervention. Retinal detachments occur most often in high myopia. In patients with diabetes, detachment may also develop in advanced eye disorders.

Retinal Hemorrhages Due to Sugar and Hypertension

The two biggest enemies of the retina are diabetes and hypertension diseases. Diabetes and hypertension diseases negatively affect all systems of the body and create the greatest effect on the eyes. The problem created by diabetes in the eyes is called diabetic retinopathy. Diabetic detinopathy is the most common cause of blindness due to diabetes. For this reason, every person with diabetes and hypertension should have a regular eye examination every 6 months, regardless of whether they have any complaints.

Regular Eye Examination is Important in Retinal Diseases!

The patient who has no problems in his retina should have a retinal examination once a year, and a patient with partial problems - if he did not call the doctor earlier - once in 6 months. Apart from this, an eye should be contacted with the ophthalmologist as soon as there is any difficulty in seeing. Since diseases occurring in the retina threaten our eyesight, early diagnosis, preventive treatment and correct surgical intervention without delay are vital.

Retinal detachments and diabetic retinopathy, which lead to blindness when disregarded, can be diagnosed and treated at the Ada Hospital EYE CENTER. Technological devices are used in the diagnosis and treatment of retinal diseases, and the necessary surgical interventions are carried out quickly.


(eye pressure)

Glaucoma is the damage to the visual nerve with increased intraocular pressure. It is an insidious disease that does not show any symptoms and can only be detected by measurements made during regular eye examination. In cases where it is not diagnosed and controlled in time, it leads to vision loss, which can lead to blindness.

Advanced computer controlled devices are used in the early diagnosis of the disease in Ada Hospital. In cases where surgical intervention is required, operations are performed in our operating rooms with the necessary equipment.

Who is seen?

Usually after 45 years of age,
· Those with glaucoma disease in their family,
· Diabetes patients,
Patients with high myopia
Patients with hypertension who are not treated regularly
Those who have been on cortisone treatment for a long time have a higher risk of being seen.

Diagnostic Methods

The most effective diagnostic method is measuring intraocular pressure during normal annual eye examinations. Other diagnostic methods; eye examination, computerized visual field, NFA and TopSS.

Treatment Methods

At what stage the disease is diagnosed, the type of treatment is regulated according to the intraocular pressure value (eye pressure) at the time the disease is diagnosed and the degree of damage to the visual nerve. The main purpose of the treatment is to maintain the intraocular pressure at normal values while maintaining the visual nerve and thus the degree of vision. Treatment to be arranged according to the circuit where glaucoma is located, respectively; eye drops and tablet are laser treatment and surgical treatment

Attention When Buying Contact Lenses!

Contact lenses that are not suitable for your eyes will cause problems. For this reason, no matter what kind of contact lenses, even for cosmetic purposes, they should be taken after the doctor's examination.


only for your 'eye', only for your 'eye'

In Ada Hospital, eye surgeries are carried out in a specially equipped 'eye' operating room.

In our operating theater, where all kinds of eye-related surgeries can be performed 365 days a specialist staff and necessary equipment are available to ensure successful operations.

The patient who will be operated comes to the hospital shortly before the operation. After the doctor's examination, the necessary examinations are carried out, the final checks are reviewed. When all the preparations are completed, he is taken to the operating room. Eye surgery is performed under general or local anesthesia in an environment where the patient, who is taken to the operating room, and the anesthesiologist is also present. The patient can be discharged the same day shortly after surgery.
