A type of under-eye implant includes two mirror-symmetrical implant units. Each implant unit is arc-shaped, tapering at both ends and thickening in the middle along its length. All edges and surfaces are smoothly transitioned through rounded surfaces. The arc trajectory of the implant unit matches the natural contour of the lower eyelid from the inner corner to the outer corner, with the radius of curvature of the inner segment near the inner corner being larger than that of the outer segment near the outer corner. Each implant unit has a through-hole at each end. The implant is made of expanded polytetrafluoroethylene (ePTFE), whose microporous structure induces tissue cell ingrowth after implantation, preventing implant displacement and light transmission, and demonstrating good biocompatibility.
