An intraocular lens having a light-transmitting optic () comprised of a synthetic light-refractive material () operably coupled with a flexible optic positioning member () to refract light onto the retina in order to correct refractive errors in the eye (). The refractive material has an index of refraction of from about 1.36 to 1.5 or higher. The optic positioning member () is constructed of a flexible synthetic resin material such as polymethylmethacrylate and permits focusing upon objects located near to and far from the viewer. The optic () of the present invention possess greater refractive capability than optics conventionally used in IOL construction, and permits retinal receipt of the image being viewed in order to correct refractive errors.

An improved intraocular lens () is provided which more closely mimics the accommodation and focusing of the eye's natural lens. The lens () comprises an optic () and a flexible, resilient optic positioning element () which includes an anterior section (), a posterior section (), a bight (), in cross-section, joining the anterior and posterior sections, and a haptic arm () extending between the optic () and the optic positioning element (). The lens () may optionally include a posterior optic () coupled to the optic positioning element (). The optic positioning element () is formed of unitary construction. The anterior () and posterior () sections are configured for yieldable engagement with the anterior () and posterior () walls of the eye capsule (), respectively.
