[Photorefractive keratectomy in hypermetropia].

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.
