Visual Function Outcomes in Tinted versus Non- Tinted IOLs in Cataract Patients

Abstract

Aims: The study aims to compare the visual function outcomes in tinted versus non-tinted IOL in cataract patients. Study Design: Prospective, randomised, clinical study was conducted on patients. Place and Duration of Study: The study was carried out at Upgraded Department of Ophthalmology, Government Medical College Jammu, India during November 2016 to October 2017. Methodology: This study included two groups of 100 patients each. 100 patients in group 1 were randomly implanted with tinted IOLs, and another 100 patients in group 2 were implanted with non-tinted IOLs. Visual functions such as Best Corrected Visual Acuity (BCVA), Colour Vision (CV) and Contrast Sensitivity (CS) were compared after 1st post-operative day, 2nd week and 3rd month. Results: The mean changes between the uncorrected visual acuity (UCVA) (day 1) and best corrected visual acuity (3rd month) reveals a non significant change between the two groups, however, the mean change in tinted group was more than nontinted groups i.e. 76.17% (p =0.101). Pre- and Post-operative colour vision remained same in both the groups and mean change in contrast sensitivity after day 1 and contrast sensitivity (3rd month) also revealed a non significant change, however mean change in tinted group was more (64.55%) in compared to non-tinted group (33.28%) with p value of 0.283. Conclusion: The mean change in best corrected visual acuity and contrast sensitivity is statistically insignificant for both the groups.
