摘要：
The invention relates to the field of ophthalmic surgery and can be used for simultaneous marking capsulorhexis and the astigmatic axis of the toric intraocular lens with its implantation.The technical problem of the invention - improved accuracy markup capsulorhexis and the astigmatic axis of the toric intraocular lens with the pupil of the broad and narrow, reducing the operation time.The technical problem is solved by a toric scriber comprising a handle and a working part of a ring, the working part is designed as a cylindrical ring provided with diametrically spaced tapered projections, and two first projections are arranged on the inner side of the cylindrical ring and face tapering part to the center of symmetry and two second side located on the outer cylindrical ring portion and facing oppositely tapering platers symmetry center longitudinal axis Simm Rhee all four projections coincide wherein each projection is bounded by a plane inclined relative to the vertical axis of the device at an acute angle, wherein each wedge-shaped projection facing the base to the upper surface of the outer ring, and an acute angle at the apex to the bottom surface of the ring wherein the bottom surface of the wedge-shaped projections, interacting with the surface of the cornea, made concave with respect to the plane of the rings with an average radius equal to the mean radius of curvature of the eye cornea and a lower surface sharpened ring wherein the diameter of the ring is in the range from 4.0 mm to 5.5 mm, the vystoyanie each outer wedge ring relative to the projection center is in the range from 4.5 mm to 6.0 mm.Полезная модель относится к области офтальмохирургии и может быть использована для одновременной разметки капсулорексиса и астигматической оси торической интраокулярной линзы, при ее имплантации.Техническая задача изобретения - повышение точности разметки капсулорексиса и астигматической оси торической интраокулярной линзы при широком и узком зрачке, сокращение вр
