INTRAOCULAR LENS AND METHOD FOR PREVENTING SECONDARY OPACIFICATION

摘要

An intraocular lens for receiving the lens bag of an eye in which the natural lens has been removed and matching circular openings in the anterior and posterior capsule of said lens bag have been created, said intraocular lens comprising: a central optical part (14) for projecting an image on the retina of said eye; a peripheral haptic part surrounding said central optical part, said peripheral haptic part having an inner diameter that is slightly larger than said matching circular openings in the anterior and posterior capsule of the lens bag over the entire 360 degree circumference, said peripheral haptic part having an outer diameter that is sufficiently large enough to provide a stable fixation of said intraocular lens in said eye, and the maximum axial thickness of said peripheral haptic part is less than or equal to the minimum axial thickness of said central optical part; wherein, said peripheral haptic part further comprising an anterior lip (18) and a posterior lip (20), said anterior and posterior lip delineating a circumferential groove (16) of such width and depth to accommodate said matching circular openings in the anterior and posterior capsule of the lens bag; and whereby, the implantation of said intraocular lens minimizes the risk of secondary opacification of said lens bag and the risk of luxation inside said eye. 1930 ט" ז באב התשס" ב - July 25, 2002
