About Ophthalmic Reconstructive Surgery

Reconstructive surgery of the eye takes place following irreparable damage to the eye’s integrity. Such damage can result following trauma, iatrogenic damage (damage caused unintentionally during a surgical procedure) or as a result of an inflammatory/connective tissue disease process. In these instances, the tissue can incur such damage that direct and immediate closure becomes impossible, making patching the area with preserved and processed tissue the only treatment option.

CorNeat EverPatch

The CorNeat EverPatch (scleral patch) is the first inert, synthetic and nondegradable tissue substitute for use in ophthalmic surgeries. The CorNeat EverPatch replaces the use of human tissue and degradable collagen patches for covering and concealing implants such as glaucoma drainage devices and sealing the eye in cases of missing tissue.   
 
The CorNeat EverPatch is composed of a non-woven, polymer matrix, which imitates the extracellular matrix, stimulating cellular colonization and integration with the surrounding tissue. 

Indications 

Reinforcing the sclera and aiding the physical reconstruction of the ocular surface

Concealing irritating ophthalmic implants such as glaucoma tube shunts and scleral sutures, used in scleral fixations of IOLs, displacing the need for preserved tissue/collagen

Covering tissue gaps/weaknesses, resulting either from traumatic, disease related or iatrogenic damage

Regulatory Path

The CorNeat EverPatch is following a 510K clearance path and is expected to be approved for marketing early in 2023, with the following intended use: implantation to reinforce the sclera and aid the physical reconstruction of the ocular surface. 

The current pivotal study is geared toward obtaining a CE marking early in 2024, for wider indications that include: the concealment of artificial ophthalmic implants, such as glaucoma shunts and scleral sutures used in scleral fixations of IOLs, from the overlying conjunctiva. 

 

The plans above are subject to regulatory approvals and requirements.
