title: Comparative study of the visual performance of various aphakic corrections.
abstract: The aim for the present study was to test the feasibility of using a front surface aspheric contact lens geometry to correct aphakic patients from a visual standpoint. Two aspheric contact lens designs are tested, using a standard visual acuity test and contrast sensitivity, and their performance is compared to a conventional spherical design. An hyperbolic front surface of eccentricity of 1.2 was chosen, as its performance was similar to the spherical contact lens.
