Haze after laser in situ keratomileusis in eyes with previous photorefractive keratectomy

In cases with previous photorefractive keratectomy (PRK), there is a risk o f developing severe haze after laser in situ keratomileusis (LASIK). We rep ort 3 patients (4 eyes) who developed severe haze after LASIK treatment for residual myopia following PRK Both PRK and LASIK procedures were performed using the VISX 20/20 excimer laser. We report the grade of haze, amount of regression, and visual acuity after the patients were treated with topical steroids. In 2 eyes, the uncorrected visual acuity was 1.0 after 1 year wi th grade I haze. In the other 2 eyes, there was a residual refractive error , and the best spectacle-corrected visual acuity was 0.7 with grade II haze . (C) 2001 ASCRS and ESCRS.
