title: Wavefront-guided photorefractive keratectomy to correct ametropia following aspheric ReSTOR implantation.
abstract: OBJECTIVE
  To describe the clinical course of three eyes of two patients who underwent wavefront-guided photorefractive keratectomy to correct ametropia following cataract extraction and aspheric ReSTOR lens (SN6AD3; +4.00-diopter model) implantation.
  
  
  METHODS
  Pre-and postoperative uncorrected visual acuity (UCVA) and best spectacle-corrected visual acuity (BSCVA), manifest refraction, and WaveScans based on the Hartmann-Shack analyzer were evaluated. The VISX STAR S4 excimer with eye tracking and iris registration was used in all cases.
  
  
  RESULTS
  Good quality WaveScans were obtained; UCVA improved in all cases and BSCVA improved or remained unchanged.
  
  
  CONCLUSIONS
  These cases demonstrate that it is possible to obtain good quality wavefront data in patients with the ReSTOR lens and to use such data to design wavefront-guided treatment to maximize uncorrected distance and near visual acuities after ReSTOR implantation.
