Abstract:
We evaluated the effect of retreatment for under- of overcorrection after laser in situ keratomileusis(LASIK). We performed LASIK enhancement after lifting flap(8 eyes) and transepithelial PRK(1 eye) for the 9 eyes of undercorrection and 1 eye of hyperopic correction after primary LASIK procedures were performed from October 1996 through May 1997. The average preoperative refractive error was -12.88D and preretreatment refractive error was -3.53D in spherical equivalent. The average period from primary LASIK to retreatment was 85.7 days and we evaluated the stability, predictability, efficacy, safety, and complications after 6 months. At 6 months postretreatment, the average refractive error was -0.31D and 8 eyes obtained a refraction within +/-1.0D of emmetropia. Uncorrectedvisual acuity(UCVA) was improved from 0.24 to 0.71. There was one eye with grade III corneal haze and decentration after transepithelial PRK on corneal flap. And it had 1 line loss of best corrected visual acuity(BCVA) compared with preretreatment BCVA. The final average refractive error of the 7 eyes which underwent retreatment after 1 month was closer to emmetropia than that of the other 3 eyes which underwent retreatment within 1 month, but there was no statistically significant difference(p>0.05). In conclusion, LASIK tetreatment may be considered for the correction of under- and overcorrection after LASIK.
