Clinical aspects of the SR-IV Programmed Subjective Refractor.

Five studies were performed on 682 eyes of currently working and retired factory workers and some of their children. The magnitude of the refractive error and the visual acuity obtained were essentially equivalent for the two methods (SR-IV, Phoroptor). SR-IV testing required less time than conventional techniques. Patients reported the SR-IV easy to use and they expressed confidence in the results. In a separate study, the amplitude of accommodation was measured. This measurement may prove useful in estimating the near addition.

A new automated subjective optometer.

A new optometer that utilizes optically simulated distance line and letter targets, focusable by patient or operator, is described. Refractive findings for 376 eyes tested on the new optometer were compared with the findings obtained by conventional clinical methods. Most differences were within the limits of repeatability reported for conventional refraction tests.
