[Photorefractive keratectomy in hypermetropia].

PURPOSE

The purpose of this study was to assess the predictability and efficiency of the photorefractive keratectomy in hyperopia.

MATERIAL AND METHODS

Thinty-eight eyes of 21 patients with the mean age of 34.6 were included. The eyes were divided into 3 groups according to their hyperopia. Group 1: 14 eyes with hyperopia greater than +7.25 D. Group 2: 13 eyes had hyperopia ranging from +4.25 D to +7.00 D and Group 3: 11 eyes with hyperopia less than or equal to +4.00 D. All of the eyes underwent photorefractive keratectomy procedure with 193 nm argon-fluoride excimer laser (Chiron Technolas) with 10 to 30 Hz repetition rate and 120 mJ/cm2 fluence. The mean follow-up time was 12 months.

RESULTS

The mean postoperative refraction was +5.05 +/- 1.25 D. in the group 1, +4.71 +/- 1.23 D. in the groupe 2 and +1.65 +/- 0.93 D in the group 3 at the end of the year.

CONCLUSION

As a result, we suggest photorefractive keratectomy is efficient, predictable and safe for correcting hyperopia inferior to +4.00 D.
