Causes of cataract diagnosis
Like other eye diseases, cataract can be diagnosed by an eye doctor. During the examination, the presence and extent of cataracts, as well as any other problems that cause reduced vision, will be determined. It should be noted that in addition to cataracts, other complications, especially damage to the retina or optic nerve, can cause vision loss, and if these problems are severe, cataract surgery may not improve vision. In such a situation, the ophthalmologist will determine the steps and course of treatment.

Can you do daily activities such as cooking, shopping, housework, etc. without problems? And... based on the results of the examination and your answers, the ophthalmologist will determine the time of surgery.
