Abstract

We evaluated the distance and near vision of 33 presbyopic patients who wore the Anterior Constant Focus (ACF) rigid gas permeable (RGP) bifocal lens. Twenty-seven patients (82%) wore the lenses for one year; the six patients who quit the study complained of unacceptable vision (four patients) and discomfort (two patients). Twenty-five patients (76%) obtained 20/25 or better distance vision, and 28 patients (85%) obtained J2 or better near vision. Contrast sensitivity was within normal limits in 24 of 33 (73%) patients. We feel the ACF lens provides good bifocal vision in a non- translating RGP design.
