Abstract

Devices and methods for handling and depositing corneal implants onto corneal tissue. Devices and methods for packaging and storing corneal implants.

Claims

1. A corneal implant applicator apparatus, comprising

a corneal implant applicator comprising a corneal implant applicator surface with at least one opening therethrough;

a corneal implant support disposed relative to the corneal implant applicator, the corneal implant support having a corneal implant support upper surface and a corneal implant support lower surface, wherein the upper and lower surfaces have a therethrough;

a corneal implant disposed between the corneal implant applicator and the corneal implant support,

wherein the corneal implant applicator surface and the corneal implant support surface are adapted such that the corneal implant preferentially adheres to the corneal implant applicator surface rather than the corneal implant support surface when the corneal implant support is moved relative to the corneal implant applicator due to the corneal implant'"'"'s preference for adhering to the corneal implant applicator surface rather than the corneal implant support surface, and such that the corneal implant preferentially adheres to corneal tissue rather than the corneal implant applicator surface when the corneal implant applicator is moved relative to the corneal tissue due to the corneal implant'"'"'s preference for adhering to the corneal tissue rather than the corneal implant applicator surface.

2. The apparatus of claim 1 wherein the corneal implant support is adapted to be moved relative to the applicator to provide access to the corneal implant and cause the corneal implant to preferentially adhere to the corneal implant applicator.

3. The apparatus of claim 1 wherein the corneal implant comprises a hydrophilic material.

4. The apparatus of claim 1 wherein the corneal implant support is disposed relative to the corneal implant applicator to form a corneal implant chamber.
