Zusammenfassung: | A blade assembly for a microkeratome for performing a LASIK operation has a cutting blade (4) with a cutting edge (5) and a sled (3) with an arm. The blade (4) is mounted on the arm (46). The sled (3) is configured for displaceable mounting in an opening of a slide of the microkeratome such that the cutting edge (5) is parallel to a longitudinal direction of the opening and such that the blade (4) is mounted in the slide for oscillating movement in a direction parallel to the cutting edge (5). The arm is configured to elastically preload the blade (4), in a state of the sled (3) being mounted in said opening, against two guide surfaces of the slide, which form an angle with each other and are parallel to the cutting edge (5). By elastically preloading the blade (4) against the two guide surfaces, it is possible to keep the spacing between the cutting edge (5) and a plane contact surface (4) for contacting the cornea of an eye (13) accurate within a few micrometers. |
