AIM: 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 post-operative 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.
