ACCOMMODATING INTRAOCULAR LENS WITH MULTIPLE VIEWING ELEMENTS AND ENHANCED DEPTH OF FOCUS

摘要

An intraocular lens (100A) can comprise first and second viewing elements ( 106. 1 18). At least one of the viewing elements can comprise an optic having an anterior surface and a posterior surface. The anterior surface can comprise an aspheric region (164) having increased longitudinal aberration as compared to a spherical lens (100) to increase depth of focus. Alternatively, the aspheric region (164) can be located on the posterior surface of the optic, or both the anterior surface and the posterior surface can comprise aspheric regions.
