Abstract: A surgical instrument in the form of a template comprises at least one slit formed therethrough to guide either pivotal or dragging cutting movement of a surgical blade of a scalpel therein. The instrument is preferably fixedly held, by suction, over a body area to be incised. In one embodiment, the scalpel is pivotally mounted adjacent to the slit for arcuate movement about a fixed pivot to ensure accurate and reproducible incisions. In a second embodiment, grooves are formed alongside the slit to guide dragging movement of the blade. The instrument is particularly adapted for radial keratotomy wherein a plurality of radially extending and circumferentially spaced slits are formed through the instrument. The surgical blade can be adapted for adjustment, on an angularly offset handle secured thereto, to selectively vary the depth of the incision. - 1 -
