[The function of the posterior corneal epithelium after exposure to ultraviolet laser radiation]

The method of contact mirror microscopy was used for assessment of the state of posterior epithelium of rabbit corneas before and after the action of laser ultraviolet radiation, lambda = 0.337 mmc. It was found that the usage of energy density of 5-20 mwt/cm2 and time exposures [correction of expositions] of 1, 5, 10, 15 min. in the terms of follow-up from 1 hour to 3 months is harmless for cells of posterior epithelium of the cornea in experiment. The method of mirror microscopy widens criteria of in vivo objective assessment of coherent radiation action on the cornea, that is important for deciding the questions about security and optimization of energetic parameters of laser therapeutic actions.
