Simplified system of Purkinje image photography for phakometry.
Phakometry is a technique for measurement of the crystalline lens radii of curvature, usually involving photography of the Purkinje images. We have devised a system of comparison phakometry using commercially available camera equipment. This paper contains a description of the apparatus, technique, and necessary calculations. Reliability of the method is discussed.
