title: Change in postoperative refractive error when vitrectomy is added to intraocular lens implantation.
abstract: OBJECTIVE
  To compare the actual and expected refractive errors after intraocular lens (IOL) implantation alone with those after IOL implantation with simultaneous vitrectomy.
  
  
  METHODS
  Shinjo Eye Clinic, Miyazaki, Japan.
  
  
  METHODS
  One hundred thirty-six eyes had cataract extraction and implantation of a single-piece IOL using a frown incision, continuous annular anterior capsule tear, phacoemulsification, and intracapsular lens fixation. Thirty-six eyes also had vitrectomy.
  
  
  RESULTS
  Mean postoperative refractive error was 0.55 diopter (D) +/- 1.34 (SD) in eyes having no vitrectomy and 0.04 +/- 1.24 D in those having vitrectomy. The difference between groups was statistically significant (P = .047; t-test).
  
  
  CONCLUSIONS
  The refraction after simultaneous IOL implantation and vitrectomy shifted toward myopia by a mean of 0.50 D compared with that after IOL implantation alone.
