ABSTRACT:
An ophthalmic device for making a circular incision in and alter the shape of the cornea of an eye has an inner body rotatably movable axially relative to an outer body to predetermine the depth of incision. A cornea stop is slidably moveable with the inner body to engage the cornea and position the device on the eye. The device is centered on the eye by means of a centering pin which is axially slidably moveable with respect to the cornea stop. A pointer located on the inner body operates in conjunction with a bezel on the outer body to provide a read-out of depth of the incision.
