Case ReportsKeratitis from corneal anesthetic abuse after photorefractive keratectomy.
After having photorefractive keratectomy (PRK), a 29-year-old man suffered from delayed epithelial healing and corneal stromal ring infiltrates. All laboratory results including smear, culture, and biopsy for bacteria, herpes simplex virus, and Acanthamoeba were negative. ⋯ After all medication was discontinued and the eye pressure patched, the corneal epithelium healed completely. Practitioners should consider the possibility of topical anesthetic abuse in cases of keratitis after PRK.
