Patent ID: 8361098

Claim:
A surgical blade, comprising: a cutting blade configured to be moved by a surgical tool through scleral tissue of an eye to make an incision; a conduit within the cutting blade; a scleral eye implant prosthesis slidably disposed within the conduit; a plunger slidably disposed within the conduit, the plunger configured to push the scleral eye implant prosthesis out of the conduit; and a support arm having a first end and a second end, the first end of the support arm coupled to the cutting blade, the second end of the support arm configured to be coupled to a drive shaft of the surgical tool; wherein the cutting blade is curved along its length and connected to the support arm; wherein the support arm is configured to maintain a radial position with respect to a longitudinal axis of the drive shaft as the drive shaft rotates around its longitudinal axis, a longitudinal axis of the support arm substantially perpendicular to the longitudinal axis of the drive shaft; wherein the support arm is configured to rotate the cutting blade along its length circumferentially around the longitudinal axis of the drive shaft based on rotation of the drive shaft; wherein the cutting blade has a substantially flat cross-section across its width in a direction parallel to the longitudinal axis of the drive shaft and a curved cross-section across its length; and wherein the cutting blade is configured such that the rotation of the cutting blade along its length causes a tip of the cutting blade to enter into the scleral tissue of the eye at a first location, travel a curved path under a surface of the scleral tissue, and exit the scleral tissue of the eye at a second location during a single partial revolution of the cutting blade in order to create a tunnel through the scleral tissue from the first location to the second location.
