Abstract

We analyzed the topographic findings of central islands following excimer photorefractive keratectomies(VISX Twenty/Twenty, Inc, Santa Clara, CA) for myopia to evaluate whether the size of the central island was significantly different betwaen 1 week and 6months postoperatively and whether central island at postoperative 6months affected the decrease of corrected visual acuity from preoperative level. There were statistically significant differences in the indices related to the size of central island(peak, height, area) between 1 week(40 patients, 41 eyes) and 6 months(55 patients, 64 eyes) follow-up groups. In 64 eyes of 6months follow-up group, we could not find any statistically significant effect of the indices related to the size of central island on the decrease of corrected visual acuity, except SAI.
