Paper Abstract

Elliptical photoablations have the advantage of correcting refractive sphere and cylinder without producing transition zones. This document characterizes the geometries of ellipses used for the simultaneous correction of sphere and cylinder. The implementation of elliptical ablations in ophthalmic excimer lasers with imaged apertures is discussed.
