Purpose: To compare the scotopic contrast sensitivity and mesopic contrast sensitivity with glare of pseudophakic eyes with those of age-matched phakic eyes. Methods: Forty-one pseudophakic eyes of 41 patients (group A) with a mean age of 66.1 ±7.6 years and 41 phakic eyes of 41 age-mathced controls (group B) with a mean age of 64.9 ±6.6 were included in the study. Fotopic contrast sensitivity was measured under 85 cd/m2 luminance. Skotopic contrast sensitivity was measured under 0.032 ± 0.003 cd/m2 luminance and mesopic contrast sensitivity with glare was measured under 0.10 ± 0.01 cd/m2 luminance. The data was compared between pseudophakic and phakic eyes before and after division of each group into 3 age subgroups (group I: ² 62 years, group II: 63 - 68 years, Group III: ³ 68 years). Results: There was no statistically significant difference in photopic contrast sensitivity, scotopic contrast sensitivity and mesopic contrast sensitivity with glare between the groups A and B (P>0.05). Scotopic contrast sensitivity and mesopic contrast sensitivity with glare significantly decreased with age in both pseudophakic and phakic eyes. There was no statistically significant difference in scotopic contrast sensitivity and mesopic contrast sensitivity with glare between pseudophakic and phakic eyes within each age subgroup (P>0.05). Conclusions: Scotopic contrast sensitivity and mesopic contrast sensitivity with glare deteriorates with age both in pseudophakic and phakic eyes. There is no significant difference in scotopic contrast sensitivity and mesopic contrast sensitivity with glare between pseudophakic and phakic eyes.
