Abstract
To report the short-term outcomes and complications of implantation of scleral-fixated capsular tension rings and/or capsular tension segments with intraocular lenses (IOL) in pediatric patients with ectopia lentis. Retrospective, observational case series. Thirteen consecutive pediatric patients (19 eyes) underwent placement of in-the-bag IOL with either a Cionni modified capsular tension ring or a capsular tension segment in conjunction with a conventional capsular tension ring between January 1, 2009 and March 30, 2013 by 3 anterior segment surgeons at a single academic center. The scleral fixation suture was 9-0 polypropylene in 16 eyes and CV-8 Gore-Tex (expanded polytetrafluoroethylene) in 3 eyes. Outcome measures included change in corrected distance visual acuity (CDVA) and complications. The mean age was 10.2 years ± 4.8 (SD) and the median follow-up, 23.4 months. A Cionni modified capsular tension ring was implanted in 5 eyes and a capsular tension segment with an unsutured capsular tension ring was implanted in 12 eyes. In 2 eyes, capsular tension segment alone was placed. The mean CDVA at the final follow-up (0.10 ± 0.11 logMAR, 18 eyes) was significantly better than preoperatively (0.58 ± 0.26 logMAR, 15 eyes) (P < .001). The CDVA at the final follow-up was 20/40 or better in 18 eyes (94.7%). All IOLs were well centered. Posterior capsule opacification developed in 11 eyes (57.9%), 9 eyes (47.4%) required neodymium-yttrium-aluminum-garnet capsulotomy, and 3 eyes (15.8%) required pars plana vitrectomy and posterior capsulotomy. Other complications included broken suture (5.3%) (9-0 polypropylene at CTR eyelet, repaired with CV-8 Gore-Tex), conjunctival dehiscence (5.3%), suture exposure (5.3%) (trans-scleral 9-0 polypropylene), and vitreous strand at inferior paracentesis (5.3%). Implantation of in-the-bag IOL with either a Cionni modified capsular tension ring or a capsular tension segment in conjunction with a conventional capsular tension ring appears to be a safe and effective technique for visual rehabilitation in pediatric ectopia lentis.
