The Color vision defect in phakic vs pseudophakic eye group

Abstract

This study was aimed to determine the color vision defect in pseudophakic and phakic groups.This was a cross-sectional study with non-probability convenience sampling. The patients’ age ranged between 45 and 60 years, and they had a follow-up after one month of surgery. The visual acuity recorded ranged from 6/6 to 6/18 after refraction. All types of refractive errors after phacoemulsification surgery (acrylic IOL) were included. Posterior subcapsular opacity and other types of cataract surgery were excluded. The Panel D-15 test was used to assess color vision defects. Ethical approval was obtained from the institutional Research Ethical Committee (REC). Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 20.0.A total of 160 eyes were enrolled in this study. Among these, 70 (44%) and 90 (56%) eyes belonged to males and females, respectively. The eyes were categorized into two groups: 80 (50%) were phakic and 80 (50%) were pseudophakic. Among the 80 pseudophakic eyes, 32 eyes had tritanopia (40%), 10 eyes had deuteranopia (13%), 8 eyes had protanopia (10%), 6 eyes had combined tritanopia and protanopia (8%), 4 eyes had combined deuteranopia and tritanopia (5%), 2 eyes had protanopia and deuteranopia (3%), and 18 (23%) had no defect. Among the 80 phakic eyes, 72 (90%) had no defect, while deuteranopia was found in 1 (1.25%) eye and tritanopia in 7 (9%) eyes. Tritanopia was most commonly observed in the pseudophakic group, while the majority of the phakic group did not show any color vision defect.
