Can you tell me how do they do cataract surgery?

Cataract surgery: The make a small incision in the eye where the colored meets the white. Then go inside the eye and remove the cloudy lens ("cataract"). Then a new lens implant is placed in the eye to replace the cloudy lens that was removed.

Cataract Surgery:how: The lens: usually clear, behind iris & like a "pillow in a pillowcase". When cloudy/white & affecting vision, surgery needed. Goal: remove top part of pillow case (anterior capsule), remove pillow (cataract), keep back pillow case intact (posterior capsule), place a new lens; Goal: keep capsular bag intact; ultrasound tip can puncture/disrupt bag; More info: eyedoc2020.blogspot.com

Highly successful: Cataract removal is almost always by ultrasonic fragmentation of the lens removing the opaque portions. It is done under local anesthesia (except in children), with substitution of an artificial lens to provide corrective focus. The procedure is rapid (25 minutes or so) with quick recovery to the full visual potential. It is a triumph of modern technology.
