Abstract
An intraocular lens of the Fresnel type which is constructed so that the Fresnel surface itself is sealed by the posterior capsule surface to overcome the problems encountered in prior intraocular lenses in which the Fresnel surface is exposed. The Fresnel lens surface is recessed entirely within the posterior surface of the intraocular lens in an open recess to form a space between the posterior face and posterior capsule surface when the intraocular lens is positioned in the eye. The sealed space facilitates the use of a YAG laser for a posterior capsulotomy should posterior capsule opacification occur.
