CorNeat EverPatch 

Non-degradable tissue-integrating ophthalmic surgical matrix

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 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 synthetic and non-degradable tissue substitute for use in ophthalmic surgeries. It is poised to displace the use of donor and processed tissue, which eventually degrades and carries the risk of disease transmission.

 

The CorNeat EverPatch is composed of a non-woven, polymer matrix, which integrates with surrounding tissue and is intended to reinforce the sclera and aid the physical reconstruction of the ocular surface.

“The ideal graft material should be long-lasting, sterile, immunologically inactive, cosmetically acceptable, and readily available,” states Seminars in Ophthalmology*. The CorNeat EverPatch was designed with these goals in mind.

Sales/Commercial Implantations

The CorNeat EverPatch received FDA 510(k) clearance in June 2023. As of Q1 2023, successful implantations of the device in conjunction with glaucoma tube shunt implantations or tube revision procedures took place at leading ophthalmic centers in the US. Surgeons provided excellent feedback, noting its ease of handling and manipulation during surgery, along with the simplicity and efficiency of fixation over the tube due to preplaced holes in the CorNeat EverPatch.
