Visual outcome and complications of bilateral intraocular lens implantation in children.

PURPOSE

To determine the safety and efficacy of bilateral intraocular lens (IOL) implantation in children.

SETTING

Tertiary referral pediatric ophthalmology department.

METHODS

This retrospective study comprised 13 children (26 eyes) who had bilateral cataract surgery with IOL implantation. Patients were divided into 2 groups: congenital cases, diagnosed during the first year of life, and developmental cases, diagnosed after 1 year of age. All patients had small incision phacoemulsification with primary implantation of a poly(methyl methacrylate) or a foldable acrylic IOL. Primary posterior capsulotomy was performed in 16 eyes (61.5%).

RESULTS

Age at surgery ranged from 1 week to just under 8 years. Seven patients (53.8%) had a systemic diagnosis: Down's syndrome (n = 4); developmental delay or cerebral atrophy (n = 3). Five children with systemic problems could not cooperate with formal vision testing; 2 could fix and follow bilaterally, and 3 had central, steady, and maintained vision bilaterally. In the congenital group, 37.5% of eyes attained a visual acuity of 20/20 and 87.5%, 20/120 or better. In the developmental group, formal vision testing was possible in 4 children. Five eyes (83.3%) attained a visual acuity of 20/40 or better. Thirteen eyes (50.0%) required posterior capsulotomy. Primary posterior capsulotomy reduced the incidence of posterior capsule opacification (PCO), but there was no correlation between PCO and IOL material. One patient developed glaucoma bilaterally.

CONCLUSION

Bilateral IOL implantation was safe and produced good visual results in children of all ages with bilateral cataract.
