KERATOME
Document Type and Number:
WIPO Patent Application WO2000009055
Kind Code:
A8
Abstract:
A keratome for performing corneal resectioning. The keratome has a positioning ring to position an eyeball with the cornea protruding through the ring to be restrained by an applanation shoe surface, which may be pivoted away. A blade is suspended from its ends by a blade support which is driven by a drive mechanism, so that the blade describes a forward path between the positioning ring and the applanation shoe at a controlled distance from the applanation shoc reference surface while also oscillating laterally, and preferably without the blade or the blade support touching either the positioning ring or the applanation shoe. A guide may be disposed parallel to the blade edge to control resectioning thickness. Drive control and vacuum for the positioning ring are provided under user command by a control unit having user inputs.
