FIELD: medicine.
SUBSTANCE: contact irradiation of eye tissues within photodynamic therapy involved in infectious corneal ulcers is ensured by application of a light guide nozzle with a circular border at its bottom. Application and exposition of a photosensitiser is followed with application of a staining agent on the nozzle edge. Then the nozzle is placed on the corneal ulcer region that is followed with contact laser irradiation with fields of diametre 3 mm herewith covering the adjacent fields by 5-10% of the area. The nozzle is sequentially circled within the corneal ulcer region from periphery to the middle.
EFFECT: possibility to limit the area of one laser radiation spot with specified dimensions, thus maintaining the constant distance of the light guide end face to the irradiated surface during procedure, achieved accurate visualisation of the irradiated regions, limited area of laser irradiation by desired region, managed infectious processes, epithelised corneal ulcers with forming the smooth opacity, and prevented inflammatory complications.
