Cataract extraction is the surgical removal of cataract(s) from the eye.
There are two basic methods of cataract extraction:
- Extracapsular cataract extraction is the more modern procedure and is performed in many cases. This involves removal of the cataract-affected lens only, with the lens capsule left in place to support the remaining lens tissue and the (artificial) intraocular lens inserted during the procedure.
- Intracapsular cataract extraction is an older method during which all of the lens and lens capsule is removed before an artificial lens is inserted as a replacement.
It is useful to be aware of both of these techniques because former cataract patients may have received either treatment.
