title: [Photorefractive keratectomy in hypermetropia].
abstract: OBJECTIVE
  To evaluate the results in patients with hypermetropia having undergone photoreactive keratectomy (PRK).
  
  
  METHODS
  The authors present a retrospective analysis of the results in 40 eyes operated on PRK in the period of September 1997 to November 2002 at the Eye Clinic of the Faculty Hospital in Hradec Králové. The mean preoperation spherical refraction was 2.90 +/- 0.98 dioptry (D), the mean astigmatism being -0.82 +/- 0.78 D, visual uncorrected visual acuity (NZO) 0.37 +/- 0.37, the mean corrected visual acuity (KZO) 1.28 +/- 0.27).
  
  
  RESULTS
  One year after the operation on 31 eyes, the resulting mean spherical refraction was 0.76 +/- 1.10 D, the mean astigmatism being -1.01 +/- 0.80 D, NZO 0.77 +/- 0.18, KZO 0.99 +/- 0.21, NZO 6/12 and better was detected in 94% of surgically treated eyes.
  
  
  CONCLUSIONS
  The PRK method has been found sufficiently effective for the correction of low and medium hypermetropia.
