title: Effect of bilateral age-related cataract on stereoacuity.
abstract: OBJECTIVE
  The objective of this study is to determine the effect of bilateral age-related cataract on stereoacuity. The outcome of cataract surgery is usually measured against the gold standard of visual acuity but stereoacuity necessary for fine motor tasks is often ignored.
  
  
  METHODS
  Stereoacuity threshold was measured in 142 participants with bilateral age-related cataracts using Frisby stereo test prior to any cataract surgery and 6 weeks after cataract surgery in the second eye with bilateral monofocal PMMA PC-IOL implantation.
  
  
  RESULTS
  Significant improvement in postoperative stereoacuity was found after extraction of bilateral age-related cataracts and PMMA PC-IOL implantation (p < 0.0001). Reduced stereoacuity was associated with increased age. There was no significant correlation of postoperative stereoacuity with duration of symptoms (p = 0.883).
