The flexure and toricity of best, flat and steep fitting hydrogel lenses on the eye.

Abstract

The flexure and toricity of Bausch and Lomb Soflens fitted to seven eyes in best, flat and steep fitting relationships were measured by photoelectric keratoscopy and keratometry. Irrespective of the fitting relationship lenses were found, generally, to conform to the cornea and to transmit through to their front surfaces the whole of the corneal toricity.
