Introduction
Subjective or objective tests designed to determine whether patients with obviously impaired vision have the potential to see well following cataract surgery. These tests attempt to ascertain whether the limiting factor to visual impairment is cataract rather than other pathology. Subjective tests include the superthreshold pinhole device, Maddox rod test, laser interferometer, & Guyton-Minkowski potential acuity meter. Electrophysiologic tests are objective tests in which the response to visual stimuli is measured electronically.
