Abstract
A surgical knife blade for forming an incision of predetermined length in bodily tissue includes indicia disposed adjacent opposing portions of a cutting edge such that alignment of the opposing indicia with the tissue during insertion of the knife blade in the tissue produces an incision of the predetermined length. A method of performing cataract surgery utilizes the surgical knife blade to precisely form a smaller incision for lens removal and a larger incision for implant of the intraocular lens.
