Intraocular lens for being implanted in capsular sac during cataract surgery, has tooth with sharp edge intended in posterior capsule of sac to limit migration of epithelial cells from each haptic element towards optical part

摘要

The lens (10) has a haptic part with haptic elements (31) i.e. open lugs, placed at periphery of a central optical part (20) to position the lens in a capsular sac. A posterior face (21) of the optical part has an arris (24) at a peripheral edge (23) of the optical part, and a posterior face of each element has a proximal zone (32) near the peripheral edge. Each zone includes a tooth (35) extending on a width of each element, where each tooth has a sharp edge intended in a posterior capsule of the sac for limiting migration of an epithelial cell from each element towards the optical part.
