What is Cataract?
It is the loss of transparency of the eye lens, which is located behind the pupil and allows the incoming image to focus on the nerve layer. Thus, it becomes difficult for a clear image to fall on the nerve layer behind.
What are the Causes of Cataract?
The biggest reason is old age. The lens of the eye starts to blur over the age of 50. Diabetes, cortisone group drugs, smoking, exposure to excessive sunlight, nutritional disorders can cause cataracts to be seen at an earlier and more frequent age. A blow to the eye can cause cataracts at any age. Congenital cataract can also be seen in babies. Fevery diseases, metabolic problems and birth trauma in the mother's womb can cause congenital cataracts. Having cataract in the family increases the risk of its occurrence in children.
What Are the Symptoms of Cataract?
Cataract can cause far or near vision, glare, not recognizing human faces or road signs, and watering. In core cataract, distance vision is blurred, but there is a serious relief in near vision, albeit temporarily. In posterior membrane cataract, distance vision is relatively good, but near vision is very impaired, there is also severe glare in bright light. When the cataract progresses, far and near vision deteriorates. In mature cataracts, vision is completely lost. Only the sensation of light is perceived.
How Is Cataract Treated?
It is not possible to treat cataract with medication or glasses. An effective method has not been found to stop its progression. The only treatment is surgery. The surgery is based on the system of removing the eye lens that has lost its transparency and replacing it with a new eye lens. The most up-to-date surgical system for cataract treatment is Phaco surgery. Phaco device melts the cataract in the eye with the help of sound waves vibrating 40 000 times per second. Thus, after cleaning the cataract, the foldable lens made of acrylic material is placed in the eye.
Thanks to the phaco device, the operation is completed by entering into the eye from a very small area. It can be applied to all kinds of cataracts. The procedure time is shortened and the safety of the operation is increased. There is no need to suture while completing the procedure. Postoperative recovery is very fast and the daily activities of the patient are not affected.
How is Phaco Surgery Applied?
Before the operation, a detailed eye examination of the patient is made. The number of the eye lens is measured with ultrasound. The patient undergoes surgery before hospitalization. Phaco surgery is performed with narcosis in children. For patients who are overly nervous and unable to stop, anesthesia is provided by injecting around the eye. However, most of the patients can only be operated with the help of drops. After cleaning the cataract with phaco, the lens of the eye is doubled and placed in the area where the phaco device enters the eye. After the operation, he is not hospitalized in the hospital and is discharged on the same day. It can return very quickly.
What are the Features of the Eyepiece Placed in Cataract Surgery?
It is completely transparent and made of a special material called acrylic. It is quite durable and does not lose its transparency over time. Its size also varies according to the eye structure of the patient. The ultrasound measurement, called biometry, determined before the surgery. The quality of the acrylic eyepiece is very important. America or Europe It is necessary to prefer lenses that are of origin and that have FDA (American Food and Drug Organization) or CE approval. Our own eye lens has the ability to adapt to far and near, especially at a young age. Although multifocal intraocular lenses (multifocal) can provide this to some extent, they have not fully achieved the desired goal.
What is the recovery course after phaco surgery?
Immediately after the operation, the vision becomes blurred, but the next day a significant clarification occurs. Healing is completed within 1-2 weeks. In this period, it is necessary to use drugs against infection and allergy problems and to keep the eye away from water contact. glasses will be required.
Can Cataract Occur After Cataract Surgery?
During the phaco surgery, the posterior membrane of the lens is completely cleaned, except for the posterior membrane of the eye. Therefore, the recurrence of cataract is not in question. However, the posterior membrane, which is left in place during the surgery and where the artificial lens sits, may thicken over time. This thickening is related to the body structure and the quality of the intraocular lens used. This problem can be easily solved with the YAG laser device.
