Abstract

PURPOSE: The purpose of this study is to compare the contrast sensitivity function (CSF) between eyes of age-matched individuals with aspheric intraocular lens (IOL) and emmetropia. METHODS: A prospective hospital-based case-control study in South India was conducted to study the CSF in the eyes of patients between the ages of 50-60 years. The CSF was compared between those with emmetropia and those implanted with an indigenous aspheric IOL. Twenty-five consecutive patients were recruited in both groups. The independent sample t-test was used for analysis. RESULTS: The mean age was 53.08 ± 1.96 years and 57.68 ± 2.85 years in normal emmetropes and emmetropic pseudophakic with aspheric IOL, respectively. The mean CSF showed a statistically significant difference (P < 0.000) between the normal emmetropic eyes and pseudophakic eyes with the values being 1.91 and 1.572, respectively. CONCLUSION: The CSF was significantly better in the eyes of age-matched normal emmetropes when compared to those with an aspheric IOL implanted.
