Photorefractive keratectomy using a 213 nm wavelength solid-state laser in eyes with previous conductive keratoplasty to treat presbyopia: Early results.

Purpose: To evaluate the efficacy and safety of photorefractive keratectomy (PRK) using a 213 nm wavelength solid-state laser to treat regression in eyes that had previous conductive keratoplasty (CK) for presbyopia.

Setting: Outpatient refractive surgery center, Manila, Philippines.
