PURPOSE
To evaluate 3-year postoperative results of patients who underwent LASIK since 1996. METHODS: Forty parients (57 eyes) received excimer laser in situ keratomileusis with Visx 20/20 and the Chiron Automated Corneal Shaper microkeratome and the uncorrected visual acuity, corrected visual acuity, and refractive error were evaluated after 3, 6, 12, and 36 months. They were devided into two groups according to preoperative myopia: group I ranging from -6.00 to -10D and group II over -10.25D. RESULTS: Mean preoperative refractive error (spherical equivalent) was -10.88+/-3.94 D (-6.25 D~-24.13D) and mean postoperative refractive errors (S.E.) were -0.84+/-1.24D at 3 month, -1.26+/-1.62 D at 6 months, -1.52+/- 1.79 D at 12 months, and -2.28+/-1.78 D at 36 months. Uncorrected visual acuity was 0.5 or better in 74, 79, 69, and 54% after 3, 6, 12, 36 months, respectively and 0.8 or better in 50, 48, 46, 33%, respectively. CONCLUSIONS: These results show that LASIK for high myopia was a safe method, but myopic regression was observed even after 3 years. |
