Formatted Abstract/Summary
Purpose
To report the long-term visual outcomes and complications after implantation of scleral-fixated posterior chamber intraocular lenses (PC IOLs).

Setting

Princess Alexandra Hospital, Mater Hospital, and Queensland Eye Institute, Brisbane, Australia.

Design
Case series.

Methods

This study reviewed the records of patients who had anterior vitrectomy and scleral-fixated PC IOL implantation between 1993 and 2008 and had a minimum follow-up of 6 months.

Results

The study comprised 82 eyes of 72 patients (47 men). The mean follow-up was 83.3 months (range 6.7 to 166.5 months) and the mean age at surgery, 62 years (range 15 to 97 years). The mean improvement in corrected distance visual acuity (CDVA) was 1.6 Snellen chart lines of vision, which was statistically significant; 59 eyes (72%) had an improved or unchanged CDVA, and 23 eyes (28%) had a reduced CDVA. The most common postoperative complication was ocular hypertension (25 eyes [30.5%]). Suture breakage occurred in 5 eyes (6%) after a mean of 4.9 years; 4 of these patients were younger than 40 years. Overall, 44 eyes (53.7%) had at least 1 complication, 36.4% within 1 week postoperatively and 63.6% after 1 week. Thirteen eyes (15.8%) required at least 1 further operation.

Conclusions
Scleral-fixated PC IOL insertion provided favorable visual outcomes in many cases. Complications were common, and suture rupture is an important long-term complication, particularly in young patients. These issues affect IOL choice for the surgical treatment of aphakia and should be discussed with patients during the consent process.
