ABSTRACT
A cataract is a cloudy area in the lens of the eye that can lead to a reduction in vision and visual functions. This study was a clinical study aimed at determining the effect of cataract extraction with intraocular lens (IOL) implant on contrast sensitivity, color vision and photostress recovery time. A total of 70 patients who visited Ajeromi General Hospital, Lagos, Nigeria were used for the study. Contrast sensitivity was assessed using the Pelli-Robson contrast sensitivity chart. The colour vision of the subjects was assessed using Ishihara Pseudochromatic colour vision chart and the photostress recovery time was assessed using a bright ophthalmoscope light. Results showed that the mean contrast sensitivity of the subjects before cataract extraction with IOL implant was 1.04±0.08. After cataract extraction, the mean was 2.19±0.07. The mean colour vision test value before cataract extraction with IOL implant was 14.41±0.53. After cataract extraction, the mean was 16.00±0.00. The mean Photostress Recovery Time before cataract extraction with IOL implant was 55.77±1.81 seconds. After cataract extraction, the mean was 29.11±0.83 seconds. SPSS data analysis with the Paired sample T-Test at 0.05 level of significance showed a significant improvement (P<0.05) in contrast sensitivity, color vision and photostress recovery time before and after cataract extraction with IOL implant. It was recommended that all patients with monocular and bilateral cataract be referred for cataract extraction with intraocular lens (IOL) implant.
