AIMS Phototherapeutic keratectomy with an excimer laser is commonly used to treat recurrent corneal erosion syndrome. The aim of this study was to determine the success of a repeat phototherapeutic keratectomy for patients with persistent macroerosions following initial treatment with phototherapeutic keratectomy. METHODS Eight patients who failed primary phototherapeutic keratectomy for recu...

The objective is to evaluate the effects of phototherapeutic keratectomy (PTK) in bullous keratopathy patients. Phototherapeutic keratectomy was performed in a pseudophakic patient with corneal decompensation after lens extraction, with the excimer laser Nidek EC 5000 after manual corneal epithelial debridement. There was no pain after fifteen days the laser application and during the eight mon...

BACKGROUND To compare the corneal healing response between conventional and phototherapeutic keratectomy through a masking agent, in rabbit corneas. METHODS 24 adult rabbits underwent phototherapeutic keratectomy. Animals were divided in two groups: 12 received photoablation through a masking agent (PALM gel) and the remaining 12 received conventional phototherapeutic keratectomy of equal dep...

BACKGROUND To present a method, alternative to penetrating keratoplasty, for the restoration of impaired corneal clarity with anterior stromal scarring following long-standing corneal graft failure. CASE PRESENTATION A 48-year old female who had previously underwent Descemet stripping automated endothelial keratoplasty (DSAEK) for the treatment of pseudophakic bullous keratopathy, presented w...
