Cataract, or cataract, is an eye disease in which the lens of the eye, which is a transparent organ, becomes cloudy and one feels that everything is blurred. The most common method of cataract surgery is phacoemulsification. This surgery is performed under local anesthesia of the eye. By making two incisions in the whites of the eyes and near the outer edge of the cornea, the surgeon makes a very small hole to reach the lens of the eye. The prophylaxis device is then inserted into the eye. Ultrasonic waves are used to break blurred lenses into very small pieces. These small parts come out of the eye through the suction of the device. A permanent artificial lens is then inserted into the eye.
