Purpose: To compare two techniques of retinal attachment surgery in pseudophakic retinal detachments. Methods: This non-randomized interventional study was conducted at vitreo-retina/eye unit III mayo hospitalLahore from January 2011 to August 2011. Forty eyes of different patients with Rhegmatogenous retinal detachment after pseudophakia who met inclusion criteria were included in study. They were equally divided in two groups. Group 1 was treated with scleral buckling alone while group 2 was treated with standard 20-gauge pars plana vitrectomy. Cases were followed for 6 months. On each visit complete ocular examination was carried out and results were compared at end of study. Results: Dry anatomically attached retina after 6 months was endpoint of study. There was male preponderance in both groups. About 60% cases presented with macula-off. Myopia more than 6 diopters was found in 25% cases. YAG capsulotomy was noted in 35% cases while vitreous loss was noted in 62% cases. Causative breaks were not found in 5% to 22% cases while multiple retinal quadrants were detached in 17% to 47% cases. Group 1 showed 75% attached retina at 6 months and in second group 90% retina was attached. Raised IOP was frequent complication in both groups. Ten percent cases in group one showed raised IOP even after 6 months and were managed surgically. Overall visual results were not good due to multiple factors involved but improvement in BCVA was little bit better in PPV group. Conclusion: Modern technique of pars plana vitrectomy is better than conventional scleral buckling for repair of RRD of pseudophakic eyes.
