Abstract

A five zone, centrosymmetric, multifocal intraocular lens has been developed using a design analysis approach which assumes that the optical image strength (intensity) achieved by an optical zone is linearly proportional to its aperture. The advantages of including in aspheric zone are discussed, and the optical performance of this IOL is characterized interferometrically. Optical resolution data have been obtained according to the ANSI procedure, using standard Air Force targets. These experimental data are compared with theoretical models of optical performance of diffraction-limited circular, annular, and compound circular-annular lenses.
