title: Cataract surgery as a risk factor for retinal detachment in very highly myopic eyes.
abstract: OBJECTIVE
  To evaluate the incidence of retinal detachment (RD) after cataract surgery performed by phacoemulsification in very highly myopic eyes.
  
  
  METHODS
  Retrospective, paired-eye, case-control trial.
  
  
  METHODS
  We assessed the development of RD in 930 eyes from 930 subjects (mean age = 62.5 +/- 8.5 years) affected by very high myopia (between -15 and -30 diopters) undergoing cataract surgery after uncomplicated phacoemulsification (cataract-subjected [CS] eyes). Fellow eyes served as controls. Follow-up was 36 months.
  
  
  METHODS
  Detachment of the retina.
  
  
  RESULTS
  Retinal detachment was observed in 8.0% of CS eyes compared with 1.2% of control eyes (P<0.01, chi-square test). In CS eyes, posterior RD was most common (52.7% of eyes with RD). In control eyes, peripheral detachments with or without macular involvement were most common (47.3% of eyes with RD).
  
  
  CONCLUSIONS
  Cataract surgery, despite the use of a safe technique such as phacoemulsification, increases the risk of RD development in very highly myopic eyes.
