METHOD FOR TREATING CORNEAL ECTASIA OF STAGES I AND II IN COMBINATION WITH AN EXTREMELY THIN CORNEA Russian patent published in 2022 - IPC A61F9/00 A61N5/06 A61K31/525 A61P27/02 

FIELD: medicine.

SUBSTANCE: invention relates to the field of medicine, namely ophthalmology. For the treatment of kerato ectasia of stages I and II, in combination with an extremely thin cornea, the cornea is de-epithelized, impregnated with 0.1% riboflavin solution for 30 minutes, and a bandage contact lens is applied to the cornea at the end of the operation. After saturation with a solution of riboflavin of the cornea, a Concor Benz 56 MF customized protective hydrogel soft contact lens (SCL) pre-soaked in 0.1% riboflavin solution is installed on it for 30 minutes, with a diameter of 13-15 mm in 0.5 mm increments. Then ultraviolet crosslinking is carried out in the excimer laser system “SCHWIND AMARIS” with a wavelength of 365 nm, a dose of ultraviolet radiation of 5.4 mJ/cm², a radiation intensity of 9 MW/cm², for 5 minutes. Next, the SCL is removed and a bandage contact lens is installed until the cornea is completely epithelized.

EFFECT: method stabilizes the keratectatic process with a thin cornea without the risk of damaging the endothelial cells due to the full fit of the inner surface of a customized protective contact lens without an ultraviolet filter to the anterior surface of the cornea.
