To report the short-term outcomes and complications of implantation of scleral-fixated capsular tension rings (CTR) and/or capsular tension segments (CTS) with intraocular lenses (IOL) in pediatric patients with ectopia lentis.
Retrospective, observational case series. Thirteen consecutive pediatric patients (20 eyes) underwent placement of in-the-bag IOL with either a Cionni modified CTR (M-CTR) or combined capsular tension ring and segment (CTR+CTS) between January 1, 2009 and March 30, 2013 by three anterior segment surgeons at a single academic center. The scleral fixation suture was 9-0 polypropylene in 17 eyes and CV-8 Gore-Tex (expanded polytetrafluoroethylene) in 3 eyes. Outcome measures included change in best-corrected visual acuity (BCVA) and complications.
The mean age was 10.5 years ± 4.8 (SD) and the median follow-up, 16.1 months. M-CTR was implanted in 5 eyes and CTR+CTS in 14 eyes. In one eye, CTS only was placed due to a noncontinuous capsulorrhexis. The mean BCVA at the final follow-up (0.09 ± 0.11 logMAR, 19 eyes) was significantly better than preoperatively (0.55 ± 0.27 logMAR, 16 eyes) (P < 0.001). The BCVA at the final follow-up was 20/40 or better in 19 eyes (95%). All IOLs were well-centered. Posterior capsular opacification developed in 10 eyes (50%); 8 eyes (40%) required Nd:YAG capsulotomy and 3 eyes (15%) required pars plana vitrectomy and posterior capsulotomy. Other complications included broken suture (5%) (9-0 polypropylene at CTR eyelet; repaired with CV-8 Gore-Tex), conjunctival dehiscence (5%), suture exposure (5%) (transcleral 9-0 polypropylene), and vitreous strand at inferior paracentesis (5%). There were no cases of post-operative IOL subluxation.
Implantation of in-the-bag IOL with either the M-CTR or CTR+CTS is a safe and effective technique for visual rehabilitation in pediatric ectopia lentis.
