Cataract is a common eye disease in which the natural lens of the eye behind the iris and pupil becomes blurred. Cataract surgery is one of the most common eye surgeries. Cataract can be considered the most common cause of decreased vision in people over 40 years of age and also the main cause of blindness in the world. This disease occurs when the natural lens of the eye loses its clarity. In this way, its color changes from lightness to white or dark. Due to this change, opacity is obtained, which prevents the creation of a clear image in the eye. Cataract in the early stages blur only a small part of the lens and do not cause much of a problem; But in most cases, more and more of the lens is involved and vision is impaired. Gradually, this opacity increases and the patient loses his sight. Cataract surgery is needed at this time. The rate of cataract progression varies from person to person and can progress over several years. But it should be noted that the rate of progression in young people or those with diabetes is very high.
