FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine. A corneal cutter for corneal refractivity correction comprises a ring which can stick to an eye, an applanator for corneal deformation and a blade arranged in front of the applanator and movable in a plane perpendicular to an axis of the ring, and used for pocket cutting in the corneal tissue. The blade is fixed on a blade holder or a fastener so that a top side of the blade holder is buried in relation to a top side of the blade at least within a penetration depth of the blade holder into the cornea. When applying the above cutter for cutting the pocket, the portion of the blade holder penetrates into the cornea.
EFFECT: inventions enables fastening the blade on the holder so that when penetrating into the corneal pocket, the holder complies with a cutting depth and accuracy, and at the same time performing multiple sterilisation.
