In cataract, the lens of the eye undergoes anatomical deterioration. In the early stages of the disease, various treatment methods are used to eliminate the decrease in vision. In this direction, patients are usually prescribed close glasses of the appropriate size for the decrease in near vision, some lifestyle changes are recommended, and the treatment of possible underlying health problems is emphasized. However, definitive treatment of the disease is possible by removing the anatomical deterioration in the lens. This is achieved by surgical methods. The most commonly used method in cataract surgery is phacoemulsification, or FAKO for short. In this method, the lens is divided into small pieces using special ultrasound waves and the pieces are surgically removed from the body. After the procedure, an artificial lens produced in harmony with the body is placed in the eye. In another method, the cataract lens is surgically removed through a small incision made on the corneal edge and the new artificial lens is placed directly. In some patients, the surgery is completed without lens placement, as artificial lens placement is not appropriate after cataract surgery. In these patients, vision is supported by using special glasses or contact lenses. Surgery is often performed on one eye, and when the other eye is needed, the healing process of the first eye is followed and planning is made for the second operation. Surgery is usually not performed in both eyes at the same time due to cataracts. Since cataract disease is limited to the eye lens, it makes it possible to delay the surgery to a later date. Performing cataract surgery later does not lead to a decrease in the degree of improvement in vision in the postoperative period. However, due to diseases such as diabetes and high blood pressure, cataract symptoms may increase until the surgery is performed due to the progression of the cataract.
