Summary:
Aim: To evaluate the results in patients with hypermetropia having undergone
photoreactive keratectomy (PRK).
Group and 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.
Conclusion: The PRK method has been found sufficiently effective for the correction
of low and medium hypermetropia
