OBJECTIVE: To assess visual outcome and post-operative complications after silicone oil removal in pseudophakic vitrectomized patients. METHODS:  This interventional case series study was conducted at Department of Ophthalmology, Medical Teaching Institution Lady Reading Hospital, Peshawar, Pakistan from February 2019 to January 2020. A total of 32 eyes of 32 patients were enrolled in the study after fulfilling inclusion and exclusion criteria using non-random consecutive sampling technique. All patients had pars plana vitrectomy with silicone oil done 6 months ago and were pseudophakic. Silicone oil removal was carried out in all patients and visual outcome and surgical complications assessed on 1st and 14th post-operative day. Final examination was done after six months. Statistical analysis was done by using Statistical Package for Social Sciences (version 21) by applying paired sample t-test. RESULTS:    Amongst 32 patients, 20 (62.5%) were male and 12 (37.5%) were female. Age of the patients ranged from 16 to 60 years with a mean age of 35±13.97 years. Pre operatively mean best corrected visual acuity (BCVA) was 1.45±0.52 Log Mar. On the last post-operative follow up after six months mean BCVA was 1.21±0.55 Log Mar. Visual acuity improved in 24 (75%), remained stable in 3 (9.4%) and worsening in visual acuity was seen in five (15.6%) cases. Visual improvement was statistically significant (p-value 0.001) using paired t-test. Most common complications were retinal detachment (n=4: 12.5%), secondary glaucoma (n=4: 12.5%) and epi-retinal membrane (n=2; 6.3%). CONCLUSION: Vision improves in majority of pseudophakic patients after silicone oil removal.
