Stepped microkeratome blade holder

摘要

A blade holder 16 includes a bottom surface 18 for attachment to a blade 30. A top surface 20 interfaces with a drive-pin 32 of a microkeratome 38. A drive slot 22 is formed in the top surface 20 for engagement with the drive-pin 32 for allowing oscillation of the blade holder 16. A plurality of steps 24 are formed in the top surface 20, and rise from the drive slot 22 toward at least one side 26 of the blade holder 16.
