Clinical Investigation of Soft Contact Lenses with Compensated Spherical Aberration for Correcting High Ametropia

Abstract

In conventional contact lenses, the spherical shape of both anterior and posterior optical surfaces induce spherical aberration. With lenses of higher back vertex power (BVP), previous calculations1,2,3,4 and in-vitro measurements5 suggested that the level of aberration could significantly degrade the retinal image.
