Although the eye covers a very small part of our body in volume, it is one of our most important organs. 5 with our eyes, which are called one of our sensory organs, we obtain 85 percent of the data that comes to our brain in everyday life. In this sense, it can be understood how closely eye health can be associated with body health.

Eye examination should be performed periodically during early infancy, childhood and adulthood. Currently, infants should have an eye exam at the age of 2 months, 6 months and 12 months, and the eye exam should be repeated regularly every year, even if there is no problem.

The Eye Center at IstHealth Hospital of examination and surgery; refractive surgery, cataract surgery, glaucoma, cornea, uvea-retina and vitreoretinal surgery, strabismus, Neuro-Ophthalmology, oculoplastics, contact lenses examination and inspection is carried out by doctors experienced in using the most advanced devices.

In eye examinations, computerized and manual measurement and evaluation devices such as autorefractokeratometer, airpuff and aplanation tonometers (for eye pressure measurement), biomicroscope, direct-indirect ophthalmoscope are used, and patient information is stored in a computer environment.

The most modern techniques and devices applied by experienced surgeons are used in all operations of the eye. Cataract operations are performed with seamless Phacoemulsification technique with drop anesthesia in almost all patients. Diabetes-related loss of vision pars Plana vitrectomy with internal membrane peeling limita advanced age-related macular degeneration and subretinal vitreoretinal surgery including vitrectomy surgery successfully in all kinds of complicated treatments are carried out. Corneal transplants are performed using donor corneas obtained from eye banks.

Glaucoma (eye pressure), strabismus and retinal detachment operations are performed using the most appropriate methods for the eye. Excimer laser applications for the correction of myopia, astigmatism and hypermetropia are performed by lasik method and drip anesthesia.

Refraction (crushing) defects
In general, refractive defects requiring correction by glasses, contact lenses or refractive surgery methods are evaluated in 4 groups:

Presbyopia (near vision problem after 40 years)
All refraction defects are basically caused by the inability to see far, but in farsightedness and presbyopia, vision problems near the table are also accompanied. Myopia can basically be described as an inability to see far away and is corrected with minus-numbered glasses. Refractive surgery is the most suitable refractive defect. Hypermetropia may not cause problems in childhood and youth, but it can lead to complaints such as eye fatigue and headache, especially during close studies (studying, reading books) during this period. In a later period, there is a lack of vision both soon and far away. Fixed with plus numbered glasses. Astigmatism is an axial refractive error that causes the area being looked at to be blurred. For example, when looking at the plus (+) shape, people with astigmatism see the vertical or horizontal part of the art blurred. Astigmatism is corrected with cylindrical glasses, again some astigmatism is suitable for refractive surgery. Presbyopia, on the other hand, is a near-vision defect that occurs after the age of 40. It progresses slowly and reaches its peak at the age of 55-60. Plus it’s fixed with glasses. It is also possible to correct presbyopia with intelligent lens surgery.

Refractive surgery
Refractive surgery is a common name for all of his initiatives applied to patients with vision problems due to a crushing defect. It is divided into two parts as corneal or lens surgeries. All corneal refractive surgeries basically allow you to end the use of glasses by changing the refraction in the outermost corneal layer of our eye, which looks like clock glass. These are very safe and effective surgeries when appropriate patient selection is made. Many subtypes are available, such as PRK, LASIK, LASEK, FLEX, SMILE. Appropriate myopia and astigmatism treatments with these methods can be performed quite successfully. In hypermetropia, when the patient’s choice is made well, face-laughing results can be obtained.

What to know about Excimer laser
The idea that the eye number could be changed by changing the tilt of the cornea brought up Fyodorov’s ‘scratch’ surgeries 25 years ago. In myopia, the cornea was flattened by drawing in certain shapes with diamond blades. The relative satisfaction received with this method required the search for more perfect ways. 20 years ago, researchers discovered that with excimer laser, ablation (destruction of tissue by almost vaporizing) can be performed with a thickness of 0.25 microns and consistency. Thanks to advances in this regard, excimer laser has become extremely consistent, controlled and reliable in correcting crushing defects. For about 15 years in the world and in our country, millions of people have been treated with excimer laser refractive error. Each laser pulse dissolves the molecular bonds between corneal cells. This process is sensitive to thickness up to 0.25 microns. Thanks to Excimer laser, the laser beam eliminates the tissue it targets at the targeted thickness and width, and thus the refraction of the eye is changed in the desired way. Because the eye is not scratched in this method, pressure changes do not threaten the integrity of the eye. Since the effect of the laser will only be on a specific area of the cornea, the laser will not damage the visual centers of the eye. In the beginning, the method called PRK is used, while today the lasik or lasek method is applied depending on the state of the eye. The issue of which method will be suitable for which Eye is very important and can only be understood with detailed examinations.

What is Lasik?
This method, which has been applied since 1994, is a form of lasik excimer laser made by creating a flap in the cornea. After the laser is done, the cover is tilted back into place. Thanks to the Lasik method, the pain after the laser is greatly reduced. Immediately the next day, enough vision is achieved. In LASIK, there is also the possibility of lasers for high numbers. No obvious spots occur on the cornea. It is rare for the number to return after LASIK. Stabilization of the number will be completed within 1 month. If there is enough number increase to still need glasses at the end of 1 month, the existing cover can be removed and the laser can be done again. Lasik gives successful results in suitable eyes from +6.00 hypermetropia to -12.00 number myopia. In refractive surgery, the goal is to reduce the number of the eye, if possible, completely remove it. After surgery, if the patient has as much vision as he can see with glasses without glasses, a successful result is achieved. Excimer laser treatment has received FDA approval in the United States, where health-related standards are very strict, and excimer laser has been applied to millions of eyes to date.

How is Lasik applied?
Lasik is performed under drip anesthesia. The eyelids are opened with a separator and the patient is prevented from winking. After the center of the cornea is marked, the microkeratoma, which will create a lid in the cornea, is placed in the eye. During the preparation of the valve, the feeling of light disappears for 3-4 seconds due to the pressure made by the keratoma. After the keratoma is removed, the lid opens and a laser is applied to the corneal bed. The laser process often does not exceed 1 minute. After the eye is thoroughly washed, the lid is laid in its former place and it is provided to stick to the eye. The process is terminated by dripping antibiotic drops. Two days after surgery; it can be light burning, stinging, watering. It is very important that the lid does not wrinkle after Lasik. For this reason, it is necessary not to rub the eyes for 1 month, the first days are more important. If A Wrinkle occurs, the lid can be placed back in place by the doctor.

Cataract and intraocular lenses (phaco method-smart lenses)
Cataract is the transparent lens, which is the second most important breaking organ of the eye along with the cornea, loses this property and becomes opaque. It is often seen after the age of 50. But due to different reasons, birth, infancy and youth age cataracts are also found. Currently, cataract surgery is performed seamless by Phacoemulsification (phaco) method. Seamless cataract surgery with phaco method has been the scene of great developments in recent years. Especially thanks to newly developed technologies, the ability of patients to get rid of distant and close glasses was born thanks to lenses worn according to the preferences of patients during surgery. In a similar way, astigmatic lenses can be corrected with astigmatic lenses worn during cataract surgery in people with astigmatism.

Retinal diseases and vitroretinal surgery
Diabetic eye disease
Diabetes is a disease whose frequency is increasing all over the world due to changes in eating habits and lifestyle. Diabetes, which affects small and large vessels, can cause damage to many organs in the body. The eye is one of the most severely affected organs of diabetes. Diabetes, which can cause dry eyes, refractive errors and early onset cataracts in the anterior segment of the eye, does the damage that causes the main problem in the posterior segment of the eye, that is, in the retina. If early diagnosis and treatment do not occur, it can lead to blindness.

Yellow spot disease
Yellow spot disease (age-related macular degeneration) is a condition caused by age-related deterioration of the yellow spot that provides central vision. A decrease in vision in old age is manifested by symptoms such as an inability to see the middle, irregular and interrupted vision, and a break in vision. There are two types of yellow spot disease: dry and age type. 80-90 percent of the dry type forms. In dry-type yellow spot disease, damage to nerve cells occurs gradually. This condition can return to age type in the process of time. For this reason, tracking the disease is of great importance. In age-type yellow spot disease, central vision is severely and abruptly reduced as a result of fluid and blood leakage between the retinal layers.
