Computerized analysis reveals superior optical performance of contact lenses for aphakia in the human eye.
Spot diagrams are computer generated by skew ray tracing for a model of the human eye which is corrected by means of a contact lens and spectacle lens. An examination of the images of a point source of light at 0° and 20° off the optical axis of the eye‐lens system are shown. For the correction of aphakia, the performance of the contact lens is shown to be superior in off‐axis optical performance.
