Abstract

BACKGROUND: Phototherapeutic keratectomy (PTK) is an effective treatment for many superficial corneal disorders. The efficacy of PTK for the treatment of climatic droplet keratopathy (CDK) has not been reported. METHODS: We report the results of excimer laser (Summit Technology, Inc, Waltham, Mass) PTK on 75 eyes (67 patients) with 'smooth' climatic droplet keratopathy (55 eyes) and 'irregular' climatic droplet keratopathy (20 eyes) in whom more than 6 months of follow up are available. RESULTS: PTK was successful in reducing corneal opacification in both smooth (98%) climatic droplet keratopathy and irregular (80%) climatic droplet keratopathy. Achievement of a clear or mildly hazy cornea following PTK was more likely to occur with smooth (80%) climatic droplet keratopathy than irregular (25%) climatic droplet keratopathy (P=0.01). Eyes with smooth climatic droplet keratopathy were more likely to obtain more than one line of improved uncorrected (56% vs. 25%) or spectacle-corrected visual acuity (61.8% vs. 21.2%) than those with irregular climatic droplet keratopathy (P=0.03 and 0.005, respectively). Delayed re-epithelialization (longer than 14 days) was more common in irregular CDK (21%) than in smooth CDK (9%), as was the incidence of secondary microbial keratitis (10.0% vs. 1.8%). CONCLUSIONS: PTK is effective in reducing superficial corneal opacification in CDK, although serious complications may occur, especially in advanced irregular CDK.
