ABSTRACT:
A method for shrinkage of collagen tissue by application of coherent infrared energy, in which the threshold shrinkage temperature is substantially reduced by application of a reagent such as lysozyme to the tissue prior to heating. The method is especially useful in ophthalmology for shape modification of a cornea, and is enhanced by using a corneal collagen shield as a carrier and delivery agent for the reagent and an admixed anaesthetic.
