FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to ophthalmology, and aims at treating iatrogenic keratectasia. That is ensured by removing sections of Descemet's membrane in the area of keratectasia, leaving the optic area intact. Donor corneal flap is implanted into the anterior chamber. Graft is shaped into a ring with the help of two trepans. One trepan is used to make a hole in the centre of donor tissues in accordance with the size of the optical zone of the recipient. Second trepan is cut off its edge in accordance with the size of the keratectasia damage on the recipient's cornea.
EFFECT: invention reduces traumatism of surgical operation due to reduced volume of removed tissues in recipient and promotes reduction of risk of rejection of transplanted tissues.
