TITLE: CLINICAL PROFILE, MANAGEMENT AND VISUAL OUTCOME IN PATIENTS HAVING SMALL PUPIL WITH CATARACT.

Purpose: To study causes, management options and visual outcome in patients with small pupil undergoing cataract surgery.

Setting: Institutional study, done in a tertiary care eye Institute

Methods: Patients with small pupil, maximally dilated diameter of <5mm, and Cataract, after grading as per LOCS III system were allocated into two groups. One group will undergo Phacoemulsification and the other undergoes MSICS. Patients will undergo baseline data collection preoperatively such as visual acuity (VA; best-corrected visual acuity [BCVA] using LOGMAR chart), ultrasonic biometry (by IOL master), corneal topography (by non-contact specular microscopy). The method of surgery will be decided by the operating surgeon. Pupil size will be recorded at the end of the surgery. Intra operative and post-operative complications will be studied. Patients will be reviewed on the seventh and thirtieth postoperative days. Postoperatively, we will record patients' pupillary diameter size in mm, BCVA.

Results: Pseudo exfoliation syndrome was the most common etiology for small pupil among patients in Phacoemulsification (33.3%) and SICS (34.78%) group. experience. Even though Phacoemulsification had far fewer difficulties in the trial, the two methods produced visually identical results.

Conclusion: Manual SICS and phacoemulsification do not differ significantly in complication rates and BCVA at 1 month postoperatively. No significant correlation was seen between grades of cataract and complication among patients in Phacoemulsification and SICS group.
