Contrast Sensitivity and Reaction Time in Cataract Patients: A Comparative Analysis of Pre and Post Cataract Surgery
The purpose of this study was to measure and compare pre and post-operative Contrast sensitivity (CS) and Reaction Times (RTs) in cataract patients. CS provides valuable information on visual function, independent of visual acuity (VA). It represents the ability of the eye to detect a slight difference in luminance of two regions without distinct contours. This visual function or ability is affected by various disease conditions of the eye including cataract.
