Abstract
BACKGROUND: Laser in situ keratomileusis (LASIK) is the procedure of choice for high myopia. We present a study of 85 eyes undergoing LASIK for myopia between -1.00 and -3.50 diopters (D) and assess the safety and efficacy of the procedure for treatment of low myopia. METHODS: Eighty-five eyes of 47 patients with a mean age of 29 years, (range, 18 to 56 yrs) underwent LASIK using the Chiron microkeratome and the Nidek EC-5000 excimer laser. Mean preoperative myopia was -2.09 D and mean astigmatism was 0.86 D. All other ocular pathology was ruled out before surgery. Mean follow-up was 48 days (range, 1 day to 13 mo). RESULTS: Uncorrected visual acuity of 6/9 or better at 1 week was achieved in 44 eyes (52%); at 1 month in 68 eyes (80%); and at 6 months in 70 eyes (93%). Pain score was minimal with the majority of patients having no postoperative pain. One eye suffered a serious postoperative complication of corneal abscess which resolved with treatment, but left a corneal scar and visual acuity of 6/60. CONCLUSION: LASIK is a safe and effective procedure for low amounts of myopia; it also provides early visual rehabilitation and markedly reduced pain and discomfort to patients undergoing refractive surgery.
