ABSTRACT:
The present invention includes a cutting blade for performing eye surgery. The cutting blade has a dull distal edge. The sides of the cutting blade have edges, at least a portion of which are sharp. The distal edge extends between the first and second edges in a single plane thereby defining a single line from the first edge to the second edge. The cutting blade may be mounted on a handpiece such that the dull distal edge is disposed substantially perpendicular to a longitudinal axis of the handle. The handpiece may include a micrometer control for controlling the amount of the blade which extends from the handpiece. In one embodiment the handpiece is weighted to assist the surgeon in deepening the incision. In addition, transparent footplates may be mounted on the handpiece. In use, the blade of the present invention may be used alone or in combination with conventional surgical blades. With the use of the dull distal edge and the sharp edges of the blade of the present invention, an incision made in the cornea of an eye may be evened-out at its bottom and deepened across almost its entire length to almost 100% of the cornea thickness without perforating the cornea. In one embodiment, prior to cutting, a marking device of the present invention may be used to mark a pattern of incisions on the cornea of the eye. The marking device of the present invention includes concentric rings attached to each other by radially extending supports and the combination is attached to an end of a handle. The two concentric rings define the maximum length of the radial incisions.
