Primary Vers U S Secondary Implantation of Scleral Fixated Posterior Chamber Intraocular Lens

Abstract

To assess and compare the visual outcome of primary and secondary implantation of scleral fixated posterior chamber intraocular lens (SFIOL). METHODS: This is a retrospective study of 45 eyes of 44 patients who had undergone SFIOL procedure from July 2008 to February 2014. SFIOLs were implanted as a primary procedure or as a secondary procedure and the results which included the visual outcome in the two groups were compared and analyzed. RESULTS: There were 18 and 27 eyes in which SFIOL was implanted as primary and secondary procedure, respectively. Follow up ranged from 3-24 months. Mean log MAR postoperative best corrected visual acuity in primary procedure was not significantly different (0.39(SD=0.21)) from that of secondary procedure (0.42(SD=0.25)) (p = 0.64). Post-operative best corrected visual acuity of 6/18 or better was achieved in 66.67% and 70.37% in primary SFIOL and secondary SFIOL group, respectively. In primary group 12 eyes (66.67%) had early complications as compared to 9eyes (33.33%) in the secondary group (p = 0.03). Late complications were observed in 5 eyes (27.78%) of primary SFIOL and 1 eye (3.70%) of secondary SFIOL. CONCLUSION: Secondary implantation of SFIOL seems to have a lower early complication rate than primary implantation although the final visual acuity and late complication rate are not significantly different. Hence, SFIOL offers a novel approach towards visual rehabilitation of aphakic patients who have zonular dehiscence or lack capsular support.
