Patent ID: 11744698

Abstract:
A method improves depth of focus in a first eye only by adding a higher order aberration (HOA) to the first eye by adding a monofocal optical device to the first eye. The method may also correct a spherical aberration in a second eye by inserting a monofocal aspheric IOL. The HOA added to the first eye may be selected from the group consisting of spherical, trefoil and coma. Additionally, the monofocal optical device inserted into the first eye may comprise a monofocal aspheric IOL that adds spherical aberration to the first eye. The optical device inserted into the first eye may comprise a 20 D monofocal aspheric IOL that adds 0.4 μm of spherical aberration to the first eye at 6 mm entrance pupil and adds 0.1 μm of spherical aberration to the first eye at 4 mm entrance pupil.
