A surgical tool includes a housing (102) having a driver and a surgical blade (106) configured to be bi-directionally rotated by the driver. The surgical tool also includes a footplate (108) configured to receive the surgical blade. The footplate includes a bottom portion (702) configured to rest on ocular tissue of a patient's eye. The bottom portion includes a slot (704, 706) 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.
