[LASIK for high and moderate hyperopia].
OBJECTIVE
To evaluate safety and efficacy of excimer laser in situ keratomileusis (LASIK) for high and moderate hyperopia.


METHODS
LASIK was performed on 17 eyes of 9 patients using the SCHWIND KERATOM-F excimer laser. The range of preoperative spherical equivalent was + 5.50 to + 9.00 D, and its mean value, (+ 7.18 +/- 1.00) D. All the cases were followed up for 12 months or longer.


RESULTS
There was no serious complication during the operation. No eye lost more than 1 line of the best corrected visual acuity after surgery. At 12 months, the mean postoperative spherical equivalent was (+ 1.77 +/- 1.56) D. 52.9% of eyes reached 0 to + 1.00 diopter. 88.2% of eyes achieved an uncorrected far vision of >or= 0.5. 100.0% and 76.5% eyes got uncorrected near visual acuities of >or= 0.5 and >or= 1.0 respectively.


CONCLUSIONS
It is demonstrated the LASIK is a safe and effective technique for the treatment of high and moderate hyperopia. Further algorithm calibration must be made to avoid undercorrection.
