Abstract

A keratome for performing corneal resectioning which functions without a need for a surface against which to press the subject cornea during surgery, facilitating access for the surgeon and reducing or eliminating mechanical part rubbing near the surgical site. The keratome has a positioning ring to position an eye with the cornea protruding through and restrained by the ring. A blade is preferably suspended from its ends by a blade support which is driven by a drive mechanism, and a guide is disposed substantially parallel to the blade. The blade describes a forward path above and at a controlled distance from the positioning ring while also oscillating laterally. 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.
