Abstract
A microsurgical instrument that includes a handle and a dissecting tip coupled to the handle is disclosed. The tip includes a blade having a generally elliptical three-dimensional geometry. The blade may include an edge having a first arc and an opposing second arc. When the instrument is used to form an intracorneal pocket for the implantation of an intracorneal optical lens, the curvature of the first arc allows the edge to dissect a first blind spot of the pocket, and the curvature of the second arc allows the edge to dissect a second blind spot of the pocket. The blade may also be formed with a first depression in its top surface and a second depression in its bottom surface. When the instrument is used to form an intracorneal pocket, the depressions reduce the drag on, and corresponding trauma to, stromal tissue.
