OBJECTIVE: To assess the long-term outcome of scleral-fixated sutured posterior chamber intraocular lens (SPCIOL) implantation in non pars plana vitrectomised eyes (1) to evaluate the long-term visual outcome, (2) to identify preoperative risk factors for poor visual outcomes, and (3) to identify the incidence of vitreoretinal complications. METHOD: A retrospective review of 65 eyes, which had not undergone pars plana vitrectomy prior to scleral-fixated SPCIOL implantation. RESULTS: In all, 65 eyes of 61 patients were analysed. The median follow-up period was 16 months (range 1-68 months). At final follow-up, 43 (66%) eyes had unchanged or improved BCVA at final follow-up. A total of 20 (31%) eyes had at least a two line improvement and eight (12%) eyes had at least a two line deterioration in final BCVA. No significant preoperative risk factors for a poor visual outcome were identified. In all, 24 eyes (37%) had per- and postoperative adverse events. These eyes were significantly more likely to have a poor visual outcome. Three eyes (4.6%) had a retinal detachment in the postoperative period, all of which had no perception of light at final follow-up. CONCLUSIONS: This study confirmed that while scleral-fixated SPCIOL intraocular lens implantation might be beneficial, there is a significant risk of per- and postoperative complications leading to loss of best-corrected vision in some eyes.
