Abstract

Changes in the topography of the cornea and the contact lens during and after adaptation to Bausch and Lomb Soflenses were measured in 7 eyes by means of keratometry and photoelectric keratoscopy. Generally, little change was found in the central or peripheral surface topography for either the cornea or the contact lens. Where small changes did occur, they were found to be independent of the original corneal curvature, the fit of the lens, or the duration of wear. Significant correlations were found, however, between the additional spectacle lens power (required over the contact lens to restore maximum visual acuity) and the change in curvature of the anterior surface of the Soflens, and between the toricity of the front surface of the contact lens and that of the cornea.
