Abstract
An instrument for positioning an intracorneal optical lens within an intracorneal pocket is disclosed. The instrument generally includes a handle and a cannula associated with and having a distal portion extending from the handle. The cannula is for fluidly coupling to a vacuum source in a first mode of operation and to a reservoir of surgical fluid in a second mode of operation. The distal portion of the cannula is for receiving the lens in a folded position around the distal portion. The distal portion has an aperture for providing vacuum to hold the lens in the folded position in the first mode of operation and for ejecting surgical fluid in an outward direction from the distal portion to help unfold the lens in the second mode of operation. Methods of using the instrument for positioning of an intracorneal optical lens are also disclosed.
