Provided herein are intracorneal inlays for correcting vision impairments by altering the shape of the anterior corneal surface. The physical design of the inlay to induce the desired change of the anterior corneal surface includes consideration of the biomechanical response of the corneal tissue to the physical shape of the inlay. This biomechanical response can differ depending on the thickness, diameter, and profile of the inlay. In one embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an 'effect' zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the 'effect' zone. In another embodiment, small diameter inlays are provided that induce 'effect' zones on the anterior corneal surface that are much larger in diameter than the inlays.
Provided therein are apparatuses, systems and methods for storing and retrieving a corneal implant and for delivering the corneal implant in or on the cornea. In an embodiment, a insertion system comprises an inserter for delivering a corneal implant to a desired location in or on the cornea. The inserter has a holding space at its distal end for holding a corneal implant therein. A solution may substantially fill the holding space with the corneal implant to keep the implant hydrated and to hold the implant in the holding space by the surface tension of the solution. The corneal implant may be preloaded in the holding space of the inserter and stored in a storage container filled with storage fluid, e.g., saline, until use. To deliver the corneal implant, the inserter is positioned at the desired location, and the corneal implant released from the holding space of the inserter.

Described herein are designs and design methods for intracorneal inlays with intrinsic dioper power (i.e., index of refraction different from the surrounding cornea tissue). The designs and design methods achieve a desired refractive change by a combination of the intrinsic diopter power of the inlay and the physical shape of the inlay, which alters the shape of the anterior cornea surface.
Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an 'effective' zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the 'effect' zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient's vision than the diameter of the inlay.
A corneal implant injector assembly includes a barrel, a plunger, and an injector tip with a channel having a size and orientation adapted to store and deliver a corneal implant. The corneal implant is preferably stored in the channel in a contracted state. The plunger has an implant engagement tip for engaging and moving the implant within the channel and to deploy the implant. In some embodiments, the injector tip is selectively detachable from the remaining portion of the injector assembly.

The implantable lenses described herein provide for modified edge regions. In one example embodiment an implantable lens includes an anterior surface, a posterior surface and an outer edge surface separating the anterior and posterior surfaces. The anterior surface can include a corrective portion and a beveled portion. The beveled portion can be located between the corrective portion and the outer edge surface. The outer edge surface can have a first portion and a second portion, where the first portion abuts the posterior surface and the second portion, and where the second portion further abuts the beveled portion. The modified edge region provides a more gradual transition between the anterior and posterior surfaces.
A corneal implant having an aspheric surface for modifying the cornea curvature and altering the corneal refractive power. The corneal implant has a lens body formed of an optically clear bio-compatible material, preferably with an index of refraction substantially similar to that of human corneal tissue (1.376). The aspheric surface is comprised of a continuous aspheric surface from the apex of the implant to beveled surface. The beveled surface, positioned near the outer diameter of the implant, is used to reduce the thickness of the aspheric surface on the periphery of the lens to the outer diameter edge. The body of the implant has a diameter between about 2.0 mm and 7.0 mm and a thickness less than about 0.150 mm.
