Abstract
To report a case of corneal haze after attempts to eliminate post–laser in situ keratomileusis (LASIK) lamellar striae. Case report. A 24-year-old woman with visually significant flap striae 2 months after LASIK underwent manual epithelial debridement and flap hydration, refloating, and stretching to eliminate the striae. Three weeks after this intervention, she developed visually significant haze that was confined to the stroma of the flap. The haze slowly improved with use of a topical steroid. Stromal haze can develop after treatment of flap striae with epithelial debridement and hypo-osmolar irrigation. We speculate that these maneuvers may have induced cell death of anterior keratocytes and led to haze formation, as can occur after simple epithelial debridement and epithelial scrape-photorefractive keratectomy.
