Abstract: Interacting cutting blades, forming a part of a rotary tissue cutter, has an outer cutting blade 28 including an edge 36 defining a port 34 formed near a distal end 30 of the outer cutting blade 28. An inner cutting blade 12 for rotation relative to the outer cutting blade 28 is held within the outer cutting blade 28. The inner cutting blade 12 includes one or more cutting elements 20 formed near a distal end 18 such that an edge 14 of the inner cutting blade 12 forms resilient frictional contact with the edge 36 and the cutting elements 20 each have a convex shape such that an apex 22 of each of the cutting elements 20 extends within the port 34 and beyond an inner surface 38 of the outer cutting blade 28 as the inner cutting blade 12 is rotated within the outer cutting blade 28.

Abstract: A microkeratome cutting-blade assembly 10 includes a cutting-blade 12 having a cutting edge 22 and apertures 18 within the blade 12. Each aperture 18 includes an inwardly-extending portion 20 on the side of the aperture 18 closest to the cutting edge 22. The assembly 10 includes a blade holder 14 having post members 16 configured to be received within the apertures 18. The cutting-blade 12 is attached to the blade holder 14 by staking the post members 16 received within the apertures 18. The cutting-blade's inwardly extending portions 20 cause the cutting-blade 12 to be maintained in accurate alignment while cold staking the post members 16 to expand and fill the apertures 18.

Abstract: Blade assembly 18 for use in a microkeratome during eye surgery includes a cutting blade 20 and a blade holder 22 attached to the blade 20. Tabs 30 are attached to the blade holder 22 to assist in aligning the blade assembly 18 with a mating slot 12 in a microkeratome to minimize damage to the cutting blade 20. Tab 30 is attached to the blade holder 22, such that the tab 30 may be detached from the blade holder 22 after insertion into the microkeratome.
