This invention discloses an implant for lower eyelid enhancement, adapted for implantation below the orbicularis oculi muscle of the lower eyelid. The implant is elongated with a triangular cross-section, the triangle having three corners. In the implanted state, the implant maintains a triangular shape with one corner pointing upwards, used to support and elevate the lower eyelid; the maximum width of the cross-section does not exceed 3mm. The implant of this invention can restore the mountain-like structure of the lower eyelid when viewed from the side, without widening. Its small volume and upward-pointing shape effectively avoid the risk of the upper edge of the implant pressing upwards and causing induced trichiasis.

This invention discloses an implant for lower eyelid enhancement, adapted for implantation below the orbicularis oculi muscle and above the tarsal plate. The implant is elongated, with a cross-section of a triangular structure with three sides concave inward. The triangular structure has three corners; in the implanted state, one corner faces upward to support and elevate the lower eyelid. The implant of this invention can recreate the mountain-like structure of the lower eyelid when viewed from the side. Its small size and effective corner support effectively avoid the risk of the upper edge of the implant pressing upward and causing ingrown eyelashes.

A meibomian gland therapeutic instrument comprises upper and lower meibomian gland heating pieces for heating upper and lower eyelids, respectively, and two sets of slide rails are arranged inside a lower shell to enable the assembly ends of the upper and lower meibomian gland heating pieces to be coupled with the slide rails in a slidable manner, achieving limiting and sliding functions, so as to facilitate flexible adjustment of the positions of the heating pieces according to the shapes of the eyelids of patients and treatment requirements, ensure close contact of the heating pieces with the eyelids, and improve treatment effects. The lower meibomian gland heating piece is preferably a lower meibomian gland heating electrode piece with heating and electrical stimulation functions, and an electrical stimulation area thereof is in contact with the eyelid to uniformly conduct electrical stimulation signals to the orbicularis oculi muscle nerves to cause blinking. The meibum is softened by heating, and pressure is generated by the interaction between the eyeball and the eyelid during blinking to promote the discharge of the meibum and dredge the meibomian gland channel. The therapeutic instrument has the advantages of simple and reliable structure, simple operation, no need for anesthetics, self-use of patients at home, high efficiency, safety and convenience.

The utility model provides a kind of meibomian gland therapeutic instrument, two pairs of upper shell and lower shell assembly form the two main body structures of therapeutic instrument, and directly connect by U-shaped connecting piece, so that overall structure is compact, stable and easily assembled and adjusted, suitable for bilateral synchronous treatment. Upper meibomian gland heating piece and lower meibomian gland heating piece are used to heat upper and lower eyelid respectively, soften the meibum in upper and lower meibomian gland, improve treatment effect. Lower meibomian gland heating piece is preferably lower meibomian gland heating electrode piece with heating and electric stimulation function, its electric stimulation area contacts with eyelid, uniformly conduct electric stimulation signal to orbicularis oculi nerve, and induce winking movement. By heating and softening meibum, and using the interaction between eyeball and eyelid during winking to generate pressure, promote meibum to discharge, dredge meibomian gland channel. The therapeutic instrument is simple and reliable in structure, easy to operate, without anesthetic, and patients can use it at home, with the advantages of high efficiency, safety and convenience.
