A modified technique of scleral fixated intraocular lenses for aphakic correction

Purpose To examine the safety and efficacy of a modified scleral fixated intraocular lens (SFIOL) technique combining a scleral tunnel for intraocular lens (IOL) insertion, horizontal passage of sutures, and performing anterior vitrectomy through self-sealing pars plana sclerostomies. Methods Retrospective review of all patients who underwent SFIOL for aphakic correction at the Department of Ophthalmology and Visual Sciences, The Chinese University of Hong Kong, Prince of Wales Hospital, Hong Kong ( a tertiary referral centre) between October 2000 and December 2001 with either the modified or conventional techniques. Results A total of 20 eyes were identified. Eight modified ( Group 1) and 12 conventional ( Group 2) with a mean follow-up of 18.3 months. Postoperatively, all the eyes improved on unaided preoperative acuity and they all had a stable and well-positioned IOL. In all, 85% (7/8) of eyes in Group 1 maintained or improved best-corrected visual acuity. Conclusions The modified SFIOL technique was found to be as safe and effective as conventional techniques. The main advantages of this technique include easy intraoperative suture management and superior globe maintenance.
