RU94030876A - Device for marking-out of eye cornea at application incisions on it - Google Patents

Abstract

FIELD: medical equipment, in particular, ophthalmologic instruments used in surgical operations at making incisions on the eye corner. SUBSTANCE: the device for marking-out of the eye cornea at making incisions on it provides for safety of the eye central optical zone by limiting the process of knife incision ensured by the offered design. The device has supporting member 1 with concave working surface 3, with curvature corresponding to the cornea curvature, and holder 2. Supporting member 1 has groove 4, made to the boundary determining the eye central optical zone, receiving limiter 5 installed on the boundary determining. The eye central optical zone. When the device is used, a measured incision on the cornea is made due to the knife stop against limiter 5 in the process of incision. EFFECT: enhanced safety of the eye central optical zone.

Claims (1)

A device for marking the cornea of the eye when applying cuts on it allows you to ensure the safety of the Central optical zone of the eye, by limiting the cutting process of the knife provided by the proposed device. The device comprises a support element 1 with a concave working surface 3 with the curvature corresponding to the curvature of the cornea, and a holder 2. The support element 1 is provided with a groove 4 made up to a border defining the central optical zone of the eye, in which a stop 5 is mounted, located on the border defining the central optical eye area. When using the device, a metered cut is performed on the cornea due to the knife stop in the limiter 5 during the cutting process.
