title: After-cataract in children having cataract surgery with or without anterior vitrectomy implanted with a single-piece AcrySof IOL.
abstract: OBJECTIVE
  To evaluate whether cataract surgery in children should be performed with anterior vitrectomy and to examine the properties of the AcrySof SA30AL intraocular lens (IOL) in the pediatric eye.
  
  
  METHODS
  Filatov Institute, Odessa, Ukraine.
  
  
  METHODS
  Cataract surgery was performed in 66 children aged 3 to 15 years. They were randomized to surgery with or without anterior vitrectomy. All eyes were implanted with the single-piece AcrySof SA30AL IOL (Alcon). During the study, the patients who needed surgery for after-cataract had a second surgical procedure. Two years after surgery, the surgical method was evaluated using exact logistic regression. Also, the Evaluation of Posterior Capsule Opacification (EPCO) score was compared between the patients who had surgery for after-cataract and the patients who did not need this. The presence of posterior synechias and centration of the IOL were assessed.
  
  
  RESULTS
  Children in the younger age group (</=62 months at surgery) had surgery for after-cataract more often than children in the older age group (P<.01). Patients who did not receive an anterior vitrectomy had surgery for after-cataract more often (P<.01). Age at surgery and whether an anterior vitrectomy was performed did not significantly affect the EPCO score. The patients who had surgery for after-cataract had a significantly higher EPCO score (P<.001). The IOL remained centered in all eyes; no eye developed posterior synechias.
  
  
  CONCLUSIONS
  This prospective study shows that cataract surgery with anterior vitrectomy is advantageous in younger patients concerning after-cataract formation. The AcrySof SA30AL maintains good centration, produces minimal inflammation, and is well tolerated in the pediatric eye.
