Abstract
To report the efficacy of phototherapeutic keratectomy (PTK) and deep lamellar keratoplasty (DLKP) in the treatment of Acanthamoeba keratitis. Two patients with delayed diagnosis of Acanthamoeba keratitis failed to respond to multiple systemic and topic antiamoebic agents supplemented by twice-weekly corneal scraping. Three weeks into such therapy, one developed a ring-shaped subepithelial infiltration and PTK was performed. The other was treated with DLKP for progressive keratitis that had invaded the midstromal layer after 50 days of medical therapy. Improvements were observed immediately after the operations and medical therapy was gradually discontinued. Best-corrected visual acuity improved to 20/20 for both patients. PTK and DLKP were found to be effective surgical procedures, especially for advanced Acanthamoeba keratitis that fails to respond to medical therapy and corneal debridement.
