This 3D medical animation shows the formation of a cataract- the clouding of the eye's lens that leads to decreased vision and its removal by two different processes; phacoemulsification and extracapsular removal. In phacoemulsification a tiny probe is inserted into the eye. The probe emits ultrasound waves that break up the cloudy lens into small fragments, then a suction device removes these fragments. This is the most common form of cataract removal surgery. This procedure usually requires no stitches. In extracapsular removal of the cataract an incision is made in the eye, and the hard center of the lens is removed. At the conclusion of each procedure an artificial lens is insert into the eye.
