title: Posterior capsule opacification in pediatric eyes with and without traumatic cataract.
abstract: OBJECTIVE
  To compare the rate of visually significant posterior capsule opacification (PCO) in pediatric eyes with and without traumatic cataract.
  
  
  METHODS
  Storm Eye Institute, Charleston, South Carolina, USA.
  
  
  METHODS
  Retrospective case control study.
  
  
  METHODS
  Eyes operated on for traumatic cataract and having in-the-bag single-piece hydrophobic intraocular lens (IOL) implantation were identified. The control group of eyes operated on for nontraumatic cataract was matched with reference to age, management of the posterior capsule, type of IOL, and follow-up duration.
  
  
  RESULTS
  Data from 58 eyes were studied. Age at surgery was comparable between the study group and the control group (7.3 versus 7.8 years) (P = .7). The rate of PCO was statistically significantly different between the 2 groups (12/29 eyes versus 2/29 eyes) (P = .002). This difference was more marked for those with intact posterior capsules (9/12 eyes [75%] and 1/12 eyes [8%] (P = .001) compared with eyes with primary posterior capsulectomy and vitrectomy (3/17 [18%] and 1/17 [6%] (P = .6). For eyes with intact posterior capsules, the duration between cataract surgery and intervention for PCO was 4 to 15 months in the traumatic cataract group; 1 eye in the nontraumatic cataract group required intervention 20 months after surgery.
  
  
  CONCLUSIONS
  Eyes with traumatic cataract were more likely to develop PCO than eyes without traumatic cataract. The results also suggest that PCO develops faster in eyes with traumatic cataract. Primary posterior capsulectomy and vitrectomy should be considered for children having traumatic cataract surgery, irrespective of age at the time of surgery.
