Laser corneal biofilm disruption for infectious crystalline keratopathy.

Crystalline keratopathy can be successfully treated by the Nd:YAG laser. We present two cases of crystalline keratopathy managed this way. A 36-year-old female contact lens wearer presented with crystalline keratopathy following recent treatment with topical steroids and antibiotics for a corneal abscess. In this case crystalline keratopathy developed despite the intensive topical antibiotic treatment. A 55-year-old man with a history of acne rosacea, chronic myelomonocytic leukaemia, asthma and Crohn's disease presented with crystalline keratopathy following an episode of infectious keratitis. Treatment with the Nd:YAG laser to the area of involvement was instituted in both cases. Noticeable resolution occurred within days, with subsequent full recovery. No side-effects from the use of the Nd:YAG laser were noted. There have been only two cases previously reported using this treatment modality.
