BACKGROUND AND OBJECTIVE: To determine posterior capsule opacification (PCO) rate and identify contributory factors in a series of patients undergoing combined 23-gauge transconjunctival phacovitrectomy. PATIENTS AND METHODS: Retrospective data on 221 consecutive patients operated on by a single senior surgeon using a standard technique were collected and subjected to univariate analysis with chi-square tests and multivariate analysis with logistic regression. RESULTS: PCO developed in 46 of 221 cases (20.8%). Major risk factors were: rhegmatogenous retinal detachment (relative risk = 3.3, P = .002), axial length greater than 24.5 mm (relative risk = 2.0, P = .093), intraoperative/postoperative complications (relative risk = 3.3, P = .04), C2F6 tamponade (versus SF6/air) (relative risk = 2.8, P = .01), and postoperative posturing (relative risk = 4.1, P < .001). Multiple logistic regression analysis showed the latter two to be most important. CONCLUSION: PCO rate following 23-gauge phacovitrectomy is lower than most rates reported for 20-gauge phacovitrectomy. Using shorter-acting gas tamponade and avoiding postoperative posturing may help lower PCO rates. Copyright 2011, SLACK Incorporated.
