Purpose: To asses and evaluate the safety and efficacy of phacoemulsification in various types of post uveitic cataract.

Methods: A total of 56 eyes of 48 patients with post uveitic cataract were operated with temporal clear corneal phacoemulsification in a period of two years between 1st January 2007 to 1st April 2009.The study included various types of post uveitic cataract namely occlusio pupillae,non dilating miotic pupil,festooned pupil,post trabeculectomy uveitic cataract and mature hard white uveitic cataracts. Standard preoperative regimen of topical as well as systemic steroids were instituted a week before surgical intervention. All cases were performed by a single surgeon under peribulbar anaesthesia using the OS3 Oertli phaco machine.

Results: Intraoperative complications were negligible with few incidents of AC instability (3.57%) , descemets stripping (1.78%),floppy iris (21.43%) ,uncontrolled rhexis formation (3.57%) and linear mark imprints at the pupillary margin due to iris retractors(44.64%).
Post operative complications included day 1 postoperative corneal oedema (41.07%), fibrinous reaction(10.71%) 6 cases, increased IOP (8.93%) ,cystoid macular oedema (12.5%), pupllary capture (1.78%) 1 case, PCO (19.64%)11 cases.More complications were observed in hard uveitic cataract. A high percentage of (78 .57 %) recorded a BCVA of 6/12 or better.

Conclusions: Adequate exposure of pupillary area using iris retractors makes phacoemulsification safe and effective in these cases and helps overcome unavoidable complications.
