title: Effect of anterior capsulorhexis optic capture of a sulcus-fixated intraocular lens on refractive outcomes.
abstract: OBJECTIVE
  To assess the effect of optic capture on the achieved refractive outcome after complicated cataract surgery with a sulcus-fixated intraocular lens (IOL).
  
  
  METHODS
  Sunderland Eye Infirmary, Sunderland, United Kingdom.
  
  
  METHODS
  Single-unit, single-surgeon retrospective case-note review.
  
  
  METHODS
  The case notes were reviewed of patients who had vitrectomy for retained lens matter after phacoemulsification or phacoemulsification with posterior capsule rupture and sulcus fixation of a posterior chamber IOL by the same surgeon. Capsulorhexis capture was attempted in all patients.
  
  
  RESULTS
  Fifty-eight eyes of 58 patients were included. The mean age was 74 years (range 47 to 99 years). Twenty-four patients (41%) had optic capture, and 34 patients (59%) had an IOL placed in the sulcus without optic capture. There was no statistically significant difference in age, axial length, or IOL power used between the groups. The mean refractive difference was +0.34 diopter (D) with optic capture and -0.40 D without optic capture (P=.0002).
  
  
  CONCLUSIONS
  The mean refractive difference for a sulcus IOL with and without optic capture was 0.74 D, equating to an IOL power change of approximately 1.00 D. The refractive results were very similar to the surgeon's personal refractive outcomes using the same IOLs in the bag (mean error +0.28), suggesting that anterior capsulorhexis optic capture gives similar results to placing an IOL in the bag.
