FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be applied for treatment of keratoconus. For this purpose ablation of epithelial layer is performed. Funnel with internal diameter, which exceeds diameter of cornea, is placed on eyeball surface. After that, funnel is filled with 0.1% solution of riboflavin on 20% solution of dextran until the volume totally covering cornea surface. When solution volume decreases, it is periodically added into funnel, supporting constant volume of solution in funnel until cornea is saturated with riboflavin solution. After that, ultraviolet irradiation of cornea with wave length 365 nm is carried out for 30 minutes. Irradiation is accompanied with additional instillations of 0.1% solution of riboflavin on 20% solution of dextran on cornea each 2-3 minutes to support its concentration.EFFECT: method ensures acceleration of cornea saturation with riboflavin, increasing treatment efficiency, makes subjective endurance of procedure tolerance easier, is simple in implementation.1 ex |
