Presbyopia usually begins after the age of 40. At this age, the ability to focus on the eye is diminishing. Thus, if the person does not experience the problem of seeing before, the close objects become blurred.

This is why most people have to use glasses. Presbyopia treatment can be done with Allotex surgery which is newly developed and made in the world by Prof.Dr.Omer Faruk Yilmaz for the first time in the world. Thus, patients can see near even in older ages without using glasses. In this method, the part of the cornea taken from the donor is placed in the eye of the patient. The method is also used in the treatment of hypermetropia.
