Abstract

PURPOSE: We have evaluated the results of laser in situ keratomileuresis (LASIK) for high myopia above -15D over the follow-up periods of three years.
METHODS
Twenty-two eyes from 15 LASIK patients were analyzed (10 eyes from 6 males and 12 eyes from 9 females). The average age was 30+/-6.7 years (20~42 years). The follow-up evaluations were performed at 6 months, 1 year and 3 years.
RESULTS
The preoperative spherical equivalent ranged from -15.00D to -37.00D (average: -20.38+/-5.06D) and the mean postoperative spherical equivalents -2.07+/-3.43D at 6 months, -3.01+/-2.88D at 1 year, -3.05+/-2.86D at 3 years. Myopic regression continued during three-year follow-up, but, was not statistically significant (p>0.05). The incidence of increased BCVA 2 lines or more was 64% at 3 years and the case of decreased BCVA 2 lines or more was not found. The mean preoperative astigmatism was -2.93+/-2.11D and the mean postoperative astigmatisms were -0.81+/-0.81D at 6 months, -1.06+/-1.07D at 1 year and -1.16+/-1.44D at 3 years. It was significantly decreased (p<0.05). The intraoperative complications were not found. The postoperative complications after 3 years were myopic regression in 8 eyes, night glare in 8 eyes, decentration in 7 eyes and the foreign bodies in the border of the flap in 1 eye and there was no corneal haze.
CONCLUSIONS
LASIK for high myopia above -15D is relatively safe. Howerver it needs further longterm evaluation.
