PurposeThe management of the posterior capsule in pediatric cataract surgery remains challenging. The purpose of our study was to evaluate the role and clinical outcomes of primary pars plana capsulotomy and pars plana anterior vitrectomy during pediatric cataract surgery with intraocular lens (IOL) implantation.MethodsConsecutive cases of pars plana capsulotomy and anterior vitrectomy during pediatric cataract surgery were retrospectively reviewed. The surgical technique was the same in all patients and involved pars plana capsulotomy with anterior vitrectomy after the IOL was implanted in the capsular bag.ResultsSeventy-six pediatric cataract cases in 61 patients performed from 1994 through 1999 used the pars plana posterior capsulotomy technique and were included in this analysis. A posterior chamber IOL was implanted in all cases. There were no intraoperative complications associated with the surgery. Median age at the time of surgery was 21 months. All patients had at least 1 year of follow-up and mean follow-up was 29.4 months. Among patients old enough to read Snellen's letters (53 eyes), final best-corrected visual acuity was 20/40 or better in 32 eyes (60%) and 20/50 to 20/200 in 21 eyes (40%). Poor final visual acuity was associated with deprivation amblyopia or optic nerve dysplasia or hypoplasia. There were no postoperative retinal complications or cases of IOL dislocation during the follow-up period. Seven eyes (9.2%) of five patients with a median age of 2.5 months developed reopacification of the visual axis at a mean of 4.1 months postoperatively. This event occurred in 6 of 28 eyes with an age of 6 months or less (21.4%), versus only 1 of 48 eyes with an age greater than 6 months (2.0%) (P =.006, Fisher exact test). The visual axis was restored by pars plana membranectomy in 6 eyes and 1 eye of one patient underwent neodymium:YAG laser membrane discission.ConclusionsPars plana capsulotomy with pars plana anterior vitrectomy is a safe, effective method of managing the posterior capsule in pediatric cataract surgery with IOL implantation. Visual axis reopacification is associated with a very young age at the time of surgery. Continued follow-up of these patients is important to assess the long-term outcomes of this surgical approach.
