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.

Abstract: Non-aspirating viscoelastics, compositions and methods of use are disclosed. The non-aspirating, transitional viscoelastics possess sufficient viscosity to be useful in ophthalmic viscosurgery, but may be left in the eye with little or no resulting IOP spike.

Abstract: A microsurgical instrument having a handle and a dissecting tip coupled to the handle is disclosed. The handle includes a cannula for transporting surgical fluid. The dissecting tip includes a blade for dissecting tissue and an aperture for delivering the fluid. The instrument may be used to more effectively create an intracorneal pocket for the implantation of an intracorneal optical lens.

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.

Abstract: IOL bodies comprising materials having a Fibronectin/Vitronectin Compatibility Index>1 and a Lens Epithelial Cell Growth Biocompatibility Index≧1 on their posterior surface have a low incidence of posterior capsule opacification.

Abstract: A microsurgical forceps having a first handle and a second handle coupled to the first handle at a hinge point is disclosed. The first handle includes a cannula for transporting surgical fluid and a first jaw with an aperture for delivering the fluid. The second handle includes a second jaw for cooperating with the first jaw. The first handle may include a second cannula for fluidly coupling to a vacuum source. The first jaw may also include a second aperture for delivering vacuum. The forceps may be used to more effectively position an intracorneal optical lens in an intracorneal pocket.

Abstract: A diffractive optical ICL made from two different hydrogel materials that are biologically acceptable for long term implantation in the cornea. The first material has a higher refractive index than the cornea and it is bound to the second material which has a refractive index similar to corneal tissue. The interface between the two materials consists of a microstructured diffractive surface. The adequate permeability of metabolites through both of the hydrogels of the diffractive ICL yields a safe implant for the cornea. Alternatively, the lens may be made of a single material and/or have an edge geometry that minimizes corneal irritation and allows the lens to sit within the corneal tissue smoothly and relatively flat.
