title: Visual results, prognostic indicators, and posterior segment findings following surgery for cataract/lens subluxation-dislocation secondary to ocular contusion injuries.
abstract: OBJECTIVE
  To determine visual outcomes, incidence of posterior segment abnormalities, and prognostic factors in eyes undergoing lens removal for cataract or lens subluxation-dislocation secondary to ocular contusion injuries.
  
  
  METHODS
  Retrospective, noncomparative, interventional case series.
  
  
  METHODS
  Forty eyes in forty consecutive patients undergoing lens extraction for ocular contusion-related cataract or lens subluxation, all with a minimum of 6 months' follow-up.
  
  
  METHODS
  Lens extraction in the traumatized eye.
  
  
  METHODS
  Final best-corrected visual acuity.
  
  
  RESULTS
  Final best-corrected visual acuity was 20/40 or better in 55% of eyes, and ambulatory vision (>5/200) was achieved in 88%. Preoperative factors associated with poorer visual outcome (<20/40) were the presence of an afferent pupillary defect or an iridodialysis (P < 0.05). Seventy percent of eyes were determined to have significant posterior segment injuries. The cause of final visual acuity less than 20/40 included macular scarring (23%), retinal detachment (15%), and optic atrophy (5%).
  
  
  CONCLUSIONS
  Cataract or lens subluxation secondary to ocular contusion injuries is often associated with severe posterior segment sequelae and poor visual outcomes.
