Cateract extraction

Ophthalmic Procedures
Labelled Diagram of the Eye

Cataract extraction is the surgical removal of cataract(s) from the eye.

A cataract is an opacity in the lens of an eye and causes reduced quality of vision.

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.
