Abstract:
1. A surgical tool comprising: a surgical blade comprising a curved cutting blade that is operable, under control of the surgical tool, to rotate through scleral tissue of an eye to make an incision; a blade stop configured to contact the surgical blade and prevent the surgical blade from revolving completely around the surgical blade's axis of rotation; and a blade guide having first and second openings; wherein the curved cutting blade is configured such that a single partial revolution of the curved cutting blade in one direction around the surgical blade's axis of rotation causes a first end of the curved cutting blade to pass through the first opening of the blade guide, enter into the scleral tissue of the eye at a first location, travel through the scleral tissue of the eye along an arc path under an outer surface of the scleral tissue, exit the scleral tissue of the eye at a second location spaced apart from the first location, and pass through the second opening of the blade guide.
