Beschreibung
Zusammenfassung:	The invention relates to medical instruments and can be used for an operatio n of refractory-correlating eximer-laser intrastromal keratectomy (REIK). The inventive cannula comprises a hollow body, a curved working part, side channels and a cavity connected to the hollow body. The side channels are us ed for instillating and/or irrigating the cornea flap while performing the refractory-correlating eximer-laser intrastromal keratectomy (REIK). Longitudinal axes of the side channels are placed across a plane of the working part bending and oriented angle-wise or angles-wise with respect to the longitudinal axis of the working part. The working part has a tapered en d for facilitating its introduction and/or a separation of tissues. The body and/or the working part are embodied with equal cross-sections and/or with cross-sections whose shapes differ from each other.
