The properties of lenses used for the correction of aphakia

There is a wide variety of aphakic lenses available but remarkably little quantitative data to assist the optometrist in his choice of product. This paper presents the results of a survey of nearly all the available lens types. Quantitative data is given for the products of those manufacturers who cooperated. Data covers off axis acuity, magnification, distortion, thickness, weight and ultraviolet protection.
