  • Patent number: 6220246
    Abstract: The ophthalmic surgical sponge is described which includes a base and a corneal shield assembly. The base allows absorption of corneal fluid during eye surgery. The corneal shield assembly is used as an absorption structure and a structure to protect the corneal cap which is formed during eye surgery, particularly in surgeries that remove tissue from the corneal stroma. The corneal shield assembly protects the corneal cap as well as the hinge of the flap during the actual tissue removal from either a laser or other tissue removing devices. Thus, the corneal cap is protected from scatter rays from the laser or other debris created from tissue removal of the cornea. Wetting the ophthalmic sponge creates a co-hesive seal so that the corneal shield assembly can seal the corneal cap securely. This seal is removable after the surgery is completed to re-expose the corneal cap and replace the cap on the cornea.
