[Photorefractive keratectomy for myopia: 6 month results]

The argon fluoride excimer laser is able to ablate the superficial cornea and to correct refractive problems. Photorefractive keratectomy (PRK) was performed on 103 myopic eyes ranging from -0.75D to -6.00D. We prospectively evaluated visual and refractive results that were followed for more than 6 months. Uncorrected visual acuity of 1.0 or better was achieved in 88.35%. The difference between attempted and achieved refractive correction was within +/- 1.00D in 94.17%. 10 eyes (9.71%) had trace to mild subepithelial hare and 19 eyes (18.45%) had loss of one line of best spectacle corrected visual acuity. The excimer laser PRK appears to be a predictable and effective method to correct myopia under -6.00D.
