A surgical tool includes a housing having a driver and a surgical blade configured to be bi-directionally rotated by the driver. The surgical tool also includes a footplate configured to receive the surgical blade. The footplate includes a bottom portion configured to rest on ocular tissue of a patient's eye. The bottom portion includes a slot configured to allow passage of a portion of the surgical blade through the bottom portion of the footplate and into the ocular tissue of the patient's eye. The footplate also includes multiple walls having multiple openings. The openings are configured to receive additional portions of the surgical blade such that the surgical blade is rotatable relative to the footplate. The footplate further includes an additional opening or open side configured to allow viewing of the surgical blade and the slot during use.
