title: Myopic photorefractive keratectomy in eyes with atypical inferior corneal steepening.
abstract: OBJECTIVE
  To evaluate the visual and refractive results of photorefractive keratectomy (PRK) in eyes with atypical inferior corneal steepening (AICS).
  
  
  METHODS
  Department of Ophthalmology, Hôpital Morvan, University of Breast, France.
  
  
  METHODS
  Using videokeratopography, we screened 310 eyes that had PRK from November 1992 through November 1993 and found that 35 eyes exhibited topographic patterns consistent with AICS with no clinical findings. The results at 6 months and 1 year were compared with those of 185 eyes with normal topography treated concurrently.
  
  
  RESULTS
  There were no statistically significant differences between the two groups in mean spherical equivalent, mean uncorrected visual acuity, and mean best spectacle-corrected visual acuity 6 months and 1 year after PRK.
  
  
  CONCLUSIONS
  After 1 year, PRK in eyes with AICS appeared to give results similar to those in eyes with normal topography. Further follow-up is needed.
