Abstract

Present work describes the study of the histomorphological status of the cornea in the central optical, middle peripheral and perilimbal zone using confocal microscopy (ConfoScan – 4) 72 patients (144 eyes) with myopia of a weak (38 people, 76 eyes) and moderate (34 persons, 68 eyes) after the appointment of OKL within 1 to 12 months. Presented the results of the histomorphological indices made it possible to single out a «stressful» period of adaptation lasting 1 month, a transitional period of 1 to 3 months, and a stable adaptation period, the formation of which was noted by 12 months of the application of OKL.Stable densities of keratocytes in various layers of the corneal stroma, endothelial cells during the entire period of observation indicated a fairly good tolerability of OKL.

Keywords
