Abstract
PURPOSE: To report the long-term outcomes and complications of iris-sutured posterior chamber intraocular lenses (PCIOLs) in the pediatric population. DESIGN: Retrospective interventional case study. METHODS: This study involved 12 consecutive pediatric patients (17 eyes) who underwent placement of foldable iris-sutured PCIOLs between September 2004 and September 2007. Outcome measures included change in visual acuity and complications. RESULTS: Of the 17 eyes were reviewed, 6 (35%) had hereditary or idiopathic ectopia lentis, 5 (29%) had Marfan syndrome, 2 (12%) were aphakic after pars plana vitrectomy and 4 (24%) were aphakic after surgical intervention for trauma. Average follow-up was 4.69 ± 3.21 years and mean age of surgery was 7.21 ± 3.78 years. Seven eyes suffered dislocation of the PCIOL an average of 12.11 ± 11.97 months after surgery, with 2 patients undergoing dislocation a second time. There was a higher rate of dislocation in patients with a history of ectopia lentis due to Marfan syndrome, idiopathic causes, or hereditary causes than in patients being treated for aphakia resulting from other causes (71% vs 29%). Mean visual acuity improved in 12 of 17 patients (71%), from 0.80 ± 0.6 logMAR preoperatively to 0.35 ± 0.5 logMAR at most recent visit, P = .009. One eye of a Marfan patient sustained a retinal detachment 8 months after dislocation of the PCIOL, and 1 patient experienced iris capture of the PCIOL after surgery. CONCLUSIONS: Iris-sutured intraocular lenses have been used as an alternative to transsclerally sutured intraocular lenses to correct aphakia in pediatric patients. Dislocation of the intraocular lenses can occur frequently, however. The procedure should be considered with caution in pediatric patients.
