We performed photorefractive keratectomy (PRK) using new multizone software of the Summit Omnimed excimer laser (Summit Technology, Inc., Waltham, Mass.) on thirteen highly myopic eyes. Average preoperative myopia was -10.94 diopters (D) (range -8.60 D to -13.50 D). Mean postoperative spherical equivalent refraction was -0.15 D (range +1.50 D to -4.00 D), at 3 months postoperatively. Uncorrected visual acuity of all the eyes improved markedly. There was no serious complication except one eye that lost two lines of spectacle corrected visual acuity possibly due to decentration. Though we need longer follow-up data and a larger sample size, the new multizone software seems to be effective for correcting high myopia.
