| abstract |
An intraocular lens (10, 110) for implanting in the posterior chamber of an eye after extracapsular cataract extraction includes a flexible filament ring (24, 124) spaced from a lens body (12, 112) to engage the posterior capsule (134) and adhere thereto due to fibrosis attachment forming a barrier enclosing an optical zone behind the lens body (12, 112) to prevent migration of crystalline, epithelial cells from the perimeter of the posterior capsule (134) to the optical zone thereby preventing opacification. |
