Abstract

INTRODUCTION:

Acrylic intraolcular lenses (IOLs) may result in lower rates of posterior capsular opacification (PCO) than poly(methyl methacrylate) lenses in children. Nonetheless, PCO frequently occurs eventually, especially in younger children. Here, we evaluated the success of neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy for the management of PCO after acrylic IOL implantation without primary capsulectomy.

METHODS:

We reviewed 73 eyes in 57 children (age 23 months to 12 years; median, 6.4 years) who underwent Nd:YAG laser capsulotomy after AcrySof IOL implantation and who had at least 3 months follow-up (range, 3-92 months; median, 25 months). The effectiveness of laser treatment was evaluated in terms of the need for repeat laser procedures or intraocular surgery to clear the visual axis.

RESULTS:

Fifty-one eyes (70%) maintained a clear visual axis after a single Nd:YAG procedure, 10 eyes (84% cumulative) after 2 Nd:YAG procedures, and another 3 eyes (88% cumulative) after 3 Nd:YAG procedures. Six eyes (8%) required pars plana membrane removal to clear the visual axis, whereas 3 eyes (4%) continue to need treatment. Life table analysis showed that the probability of continuing success after 24 months with a single Nd:YAG procedure is 68% (95% confidence interval 53-83%). In younger children (age<4 years), this rate probability was lower than in older children (35% vs. 74%; P=0.022). Two eyes developed mild transient elevated intraocular pressure. In 1 eye, the IOL was dislocated and replaced.

DISCUSSION:

Nd:YAG laser capsulotomy is an acceptable option for the management of PCO after AcrySof IOL implantation in children and produces complications infrequently.
