Efficacy of pupil expansion device in small pupil cataract surgery: a one year prospective interventional study in a tertiary care centre

Abstract

Introduction: Cataract is identified as the leading cause of moderate or severe vision impairment globally. The small, poorly dilated pupil is one of the most common difficulties faced by cataract surgeons. Literature states that small pupil cataracts accounted for about 11 percent of all cataract operations. Small pupil makes the surgery more difficult to perform and causes more postoperative damage response. The incidence of complications such as capsular rupture and vitreous loss increases remarkably. Numerous pharmacologic and mechanical strategies have been developed to increase pupil size and optimize surgical visualization. Newer Pupil expansion device provide increased points of pupillary margin fixation to provide uniform pupil dilation, resulting in a better intraoperative visualization as well as less postoperative pupil distortion Objective Of the Study: To determine the efficacy and safety of Pupil expansion device in small pupil cataract surgery undergoing phacoemulsification.
