title: Multiple excimer laser retreatments for scarring and myopic regression following photorefractive keratectomy.
abstract: Excimer laser retreatment for scarring with myopic regression following photorefractive keratectomy (PRK) has been reported. We present the 38 month course of a patient who had PRK followed by two retreatments. The patient experienced scarring with myopic regression after an initial PRK with a 5.00 mm ablation zone. These complications recurred 13 months after retreatment with a 5.00 mm ablation zone. Refractive effect, computer-assisted videokeratography measurements, and corneal clarity remained stable 12 months after a second retreatment with a 6.00 mm ablation zone, indicating that retreatment with a larger ablation zone diameter appeared to be an appropriate method for handling this complication.
