Abstract
A hand-held surgical instrument for performing ophthalmological incisions in the form of radial slits about the cornea, which are particularly suited for surgery to correct the effects of myopia or astigmatism. The instrument includes a fixation assembly having a pair of elongated arms for placement on the globe of the eye. A prong is carried at one end of each arm for insertion into the globe of the eye so that the surgeon may hold the eye in a fixed position. A linkage assembly is connected at one end to the fixation assembly and a knife assembly is connected to the other end of the linkage assembly for indexing movement about a pivot point. The knife assembly includes a knife blade holder and a knife blade carried in the holder. The blade holder is mounted for sliding movement toward and away from the pivot point so that the cutting edge of the blade will penetrate the eye to form radial slits upon the application of sufficient hand pressure.
