title: Outcome of posterior capsulotomy in late capsular block syndrome with posterior capsular opacification.
abstract: BACKGROUND
  To examine the results of neodymium:yttrium-aluminium-garnet (Nd:YAG) laser posterior capsulotomy in eyes with late or previously unrecognized capsular block syndrome (CBS) presenting with deterioration of vision owing to posterior capsular opacification (PCO).
  
  
  METHODS
  Patients, who underwent uneventful phacoemulsification with intraocular implantation and were referred for Nd:YAG laser capsulotomy owing to PCO, were prospectively examined for the presence of CBS. When indicated, Nd:YAG laser posterior capsulotomy was carried out. Prospective follow-up examinations were performed for the next 6 months. The outcome measures were post-laser change in best corrected visual acuity, refraction, change in intraocular pressure, inflammation and complication rate.
  
  
  RESULTS
  Of 655 patients referred for capsulotomy, eight had an associated CBS in that eye. These eight eyes comprised the study cases. The presence of CBS had not been recognized before the development of PCO. Best corrected visual acuity improved in all cases. In seven out of eight (87.5%) eyes refraction was unchanged throughout the follow up. Ocular hypertension, inflammation or other complications did not develop.
  
  
  CONCLUSIONS
  Nd:YAG laser capsulotomy in eyes with PCO and late or previously unrecognized CBS is a safe procedure, resulting in improved visual acuity without refractive change.
