Abstract

We retrospectively evaluated clinial results of 13 eyes of 8 patients who underwent lensectomy and 11 eyes of 7 patients who underwent LASIK(laser assisted in sity keratomileusis) for correction of high myopia. Clinical outcomes of uncorrected and corrected visual acuity, postoperative refraction, and contrast sensitivity were evaluated. Subjective tests concerning glare, night halos, or decrement of night vision were also performed in each group. Postoperative uncorrected and corrected visual acuities were not significantly different between two groups. Predicatability was significantly higher in lensectomy group than that of LASIK group. Mean contrast sensitivity value of highest frequency(20 cpd) in LASIK group was significantly lower than that in lensectomy group. Subjective glare or night hlaos occurred more in LASIK group. During follow-up, visual loss with 2 lines or more was noted in 2 eyes due to postoperative complications in lensectomy group. No complication occurred in LASIK group. LASIK has been considered reasonably predictable and safe method for correction of high myopia. But our data suggest that lensectomy may give better quality of vision postoperatively compared to LASIK for high myopia. If prophylactic treatments which are aimed to prevention of postoperative complications are carried out prior to lensectomy, lensectomy is a reasonable refractive surgical potion especially for middle-aged patients with high myopia.
