[Activity of lacrimal plasmin-like enzymes in the evaluation of the corneal state after photorefraction surgery].

Forty-three patients (58 eyes) were observed, who used contact lenses for a long time before photorefraction operations (photorefraction keratectomy and laser specialized keratomileusis--PRK and LASIK). Measurements of lacrimal plasmin-like enzymes (PLE) were carried out before and after operations on a Uniscan II microreader. Corneal and conjunctival intactness was evaluated by Bengal rose staining.

[New method of astigmatism correction: bitoric single-meridian kerato-ablation in photorefraction surgery].

The technique and results of an original method for correction of common myopic astigmatism and mixed small-sphere astigmatism by means of bitoric photokeratoablation are described. Forty-six operations were performed on patients with 2-7 diopter astigmatism. Residual 0.
