Visual thresholds in aphakia and pseudophakia.
Following extracapsular senile cataract extraction, visual thresholds were measured in 15 aphakic eyes corrected with glasses and compared with an appropriately matched group of 23 eyes with poly (methyl methacrylate) posterior chamber lenses. All subjects were six months to three years postoperative and had 20/30 or better visual acuity. The paramacular dark adapted threshold, the foveal luminance threshold, and the glare effect on both thresholds were not significantly different in the two groups despite the optical differences between aphakic and pseudophakic correction.
