Abstract
Official abstract text for this publication.
Described herein are soft contact lens sets and methods of designing soft contact lens sets based on incorporating different levels of spherical aberration into the lens design depending on the target spherical power. The different levels of spherical aberration are equal to or less than zero D/mm 2 , and account for clinically measured population-average ocular spherical aberration, manufacturing variations and generalized accommodative ability.
First claim
Opening claim text (preview).
What is claimed is: 1 . A set of non-toric contact lenses, comprising: each contact lens in said set having a first surface adapted to be placed against a user's eye and a second opposing surface, wherein the first and second surfaces meet at a lens edge defining a periphery of said lens, an optical power profile and a spherical aberration (SPHA) profile; wherein for positive optical lens powers, the SPHA profile is less than or equal to zero (0) D/mm2 and greater than or equal to −0.055 D/mm2; wherein for negative optical lens powers between about −3D and OD, the SPHA profile is less than or equal to 0.0167*SP D/mm2 and greater than or equal to −0.055 D/mm2; wherein for negative optical lens powers between −3.5D and about −3D, the SPHA profile is less than or equal to 0.0167*SP D/mm2 and greater than or equal to 0.0356*SP+0.0467 D/mm2; and wherein for negative optical lens powers between −8D and −3.5D, the SPHA profile is less than or equal to 0.0082*SP−0.0301 D/mm2 and greater than or equal to 0.0356*SP+0.0467 D/mm2. 2 . The set of non-toric contact lenses according to claim 1 , wherein for negative optical powers between −8D and −3.5D the SPHA profile is less than or equal to 0.0082*SP−0.0301 D/mm2 and greater than 0.0167*SP D/mm2. 3 . The set of non-toric contact lenses according to claim 1 , wherein for negative optical powers between −8D and about −3D the SPHA profile is less than 0.0167*SP D/mm2 and greater than or equal to 0.0356*SP+0.0467 D/mm2. 4 . The set of non-toric contact lenses according to claim 1 , wherein the first and second surfaces are selected from the group consisting of aspheric, spherical, and mixtures thereof. 5 . The set of non-toric contact lenses according to claim 1 , wherein the set comprises multifocal lenses. 6 . The set of non-toric contact lenses according to claim 1 , wherein the set comprises improved visual acuity as compared to a spherical comparator set of non-toric contact lenses.
