Gel has 0.1-2% by mass of chlorine row photosensitizer selected from a group composed of Photolon, Radachlorine and Photodithazine or 0.1-1% by mass of porphyrin row photosensitizer selected from a group composed of Photogem and Photophrin. After photosensitizing glue, covering cornea wound, being kept away from light within 30-60 min, the cornea wound exposed to laser radiation as a series of applications with 5% overlay on neighboring flash exposure spots arranged done in circle first along outer ulcer contour and finishing in the ulcer center. Irradiation power density is gradually reduced from 60-80 J/cm² when irradiating ulcer periphery to 30-40 J/cm² when irradiating ulcer center.
