Abstract

Hypothesis – Creating a capsulorrhexis which is slightly eccentric on temporal side results in lesser incidence of negative dysphotopsia.
Explanation – slight temporal capsulorhhexis leaves a broader nasal anterior capsular rim which later becomes translucent and block the peripheral rays coming from temporal side to reach nasal optic edge of IOL which causes negative dysphotopsia.
Material and method – 100 female patients with bilateral uncomplicated senile cataract were taken as study subjects. For each patient both eyes operated by same surgeon, similar technique, same IOL except only one change that in one eye CCC was central and in other eye it was slighly eccentric on temporal side. All patients were followed up for 3 months and incidence of negative dysphotopsia was recorded with the help of a subjective questionnaire.
Result – Patienst with temporal eccentric capsulorrhexis had lesser incidence of negative dysphotopsia which supported our hypothesis.
