Abstract

Abstract: : Purpose: To evaluate binocular visual performance after LASIK. Methods: We measured contrast–sensivity function (CSF, photopic and mesopic conditions) and disturbance index (for quantifying halos) under binocular and monocular conditions before and after surgery. Total aberrations were also measured. Data for 25 observers were analyzed. Results: Under mesopic conditions monocular and binocular CSF deteriorate significantly (p<0.01) after LASIK, this deterioration being higher for the binocular case. Disturbance index is also higher under binocular conditions. The deterioration increases significantly (r=0.92) with interocular–differences in eye aberrations. Conclusions: Post–surgical deterioration of contrast sensitivity and the increasing of night–vision disturbances is more accentuated under binocular conditions. New approaches in refractive surgery should include binocular analysis for optimizing visual function after sugery.
