Analysis of stray-light effects related to intraocular lens edge design.

Purpose: To study the behavior of light rays that impact the frosted, double-square edge of an intraocular lens (IOL).

Setting: Optical Phisiophatological Department, University of Florence, Florence, Italy.

Methods: The interaction of light rays as a function of the edge design of a frosted, sharp-edged IOL was evaluated using an experimental eye model and an advanced ray-tracing program.

Computerized analysis of the effects of intraocular lens edge design on the quality of vision in pseudophakic patients.

Purpose: To study the distribution and intensity of reflected glare images from 3 intraocular lens (IOL) edge designs.

Setting: Eye Institute, University of Florence, Florence, Italy.

Methods: The interaction of light rays as a function of edge design was evaluated using an experimental eye model and an advanced ray-tracing program.
