ABSTRACT:
A method of smoothing irregular corneal surfaces and removing protuberances from corneal surfaces by photoablative eximer laser keratectomy is provided. Collagen compositions for use in making collagen modulators useful in photoablative procedures are described. These compositions are applied to irregular corneal surfaces in sufficient amounts to at least fill in depressions or other irregularities on a corneal surface and are converted into a modulator, as a gel or polymerized film, prior to photoablation. The collagen modulators facilitate the photoablative smoothing of irregular corneal surfaces and protect adjacent corneal tissue from undesired photoablation.
