title: Postoperative changes in refraction and anterior chamber depth in different multifocal intraocular lenses.
abstract: To investigate the axial shift of multifocal intraocular lenses (IOLs) during the first months after implantation and to determine its potential effect on uncorrected distance visual acuity.
  
  
  
  This study comprised 8 patients (16 eyes) who received the Tecnis multifocal IOL and 8 patients (16 eyes) who received the ReSTOR multifocal IOL. Anterior chamber depth was measured with a Scheimpflug camera, and visual acuity and subjective manifest refraction were determined at 1 day, 1 week, and 1 and 3 months after surgery.
  
  
  
  The spherical equivalent refraction in the ReSTOR and Tecnis eyes, respectively, was +0.125 +/- 0.412 diopters (D) and +0.306 +/- 0.481 D at day 1, -0.375 +/- 0.280 D and -0.188 +/- 0.438 D at 1 week, -0.475 +/- 0.337 D and -0.018 +/- 0.512 D at 1 month, and 0.297 +/- 0.267 D and -0.036 +/- 0.393 D at 3 months. Anterior chamber depth in the ReSTOR and Tecnis eyes, respectively, was 3.18 +/- 0.1 mm and 3.16 +/- 0.17 mm at day 1, 3.18 +/- 0.10 mm and 3.17 +/- 0.20 mm at 1 week, 3.29 +/- 0.22 mm and 3.18 +/- 0.25 mm at 1 month, and 3.14 +/- 0.19 mm and 3.20 +/- 0.14 mm at 3 months. The change in axial position did not correlate with the change in refraction.
  
  
  
  Multifocal IOLs change their axial position slightly during the first postoperative months. The ReSTOR IOL showed a myopic change of approximately -0.50 D during this time period, which did not correlate with the change in axial position.
