Retinal tack

Definition

A sterile, non-bioabsorbable, implantable device designed to permanently fix a detached retina to the underlying retinal pigment epithelium (RPE) during ophthalmic surgery. It typically includes a conical, sharply-pointed forward end portion, an elongated cylindrical retaining portion, including one or more peripheral grooves for receiving displaced sclera tissue, and an enlarged head with a flange portion for engaging the retina in the area of the opening formed in the retina; it is intended to be pierced through the retina, choroid membrane, and sclera. The device is typically made of titanium (Ti), surgical-grade stainless steel, or a synthetic material.
