DETAILED DESCRIPTION AND BEST MODE OF IMPLEMENTATION

(16) The Tarsus Eyelid Patch heals defects on an eye's surface, as a painless option to Tarsorrhaphy, a standard surgical procedure of sewing the eyelids closed, illustrated in FIG. 1 (prior art), by painlessly and comfortably holding the upper eyelid or superior tarsus down, and holding the eye closed.

(17) In the anatomy of the eye, the flat of the eyelid is called the tarsus. The eyelids protect and help lubricate the eyes. The eyelid skin itself is very thin, containing no subcutaneous fat, and is supported by a tarsal plate. This tarsal plate is a fibrous layer that gives the lids shape, strength, and a place for muscles to attach.

(18) The tarsi or tarsal plates are two comparatively thick, elongated plates of dense connective tissue, about 2.5 cm (1.0 in) in length, one is found in each eyelid and contributes to its form and support. They directly abut the lid margins. The tarsus has a lower and upper part making up the palpebrae. The superior tarsus, tarsus superior or superior tarsal plate, the larger, is of a semilunar form, about 10 mm (0.4 in) in breadth at the center, and gradually narrowing toward its extremities. It is adjoined by the superior tarsal muscle to the anterior surface of this plate the aponeurosis of the levator palpebrae superioris is attached.

(19) The inferior tarsus, tarsus inferior or inferior tarsal plate, is smaller than the superior tarsus. It is thin, and elliptical in form, and has a vertical diameter of about 5 mm (0.2 in). The free or ciliary margins of these plates are thick and straight.

(20) The angle formed by the meeting of the upper and lower eyelids or superior tarsus and inferior tarsus, at either side of the eye is defined as the canthus. The medial canthus is the corner formed near the nose bridge. The lateral canthus is the corner formed distal the nose bridge.

(21) The present invention comprises improved procedures and articles for medically treating an eye after various surgeries or injuries, and for maintaining the health of the eye in the case of many other eye issues, including but not limited to nocturnal use to hold the eye in a closed position in matters of dry eye, lazy eye, and strokes. It will be appreciated by those in the art that anesthesiologist will use the tarsus eyelid patch during non-eye related surgeries and medical procedures where anesthesia renders a patient unconscious and a need arises to keep the anesthetized patient's eyes closed.

(22) As illustrated in the accompanying photographs and drawings, the perforated mesh device of the present invention, designated by reference numeral 2-18, is designed for comfortably holding an eye in a closed position. The eye and other eye features are designated by reference numerals 20-38. Photographs and drawings consisting of FIGS. 3-15 display a preferred embodiment of the present invention. The mesh device 2 includes a first edge 4 for insertion into an eye socket 22 medial canthus 24 of a user's face. A lateral edge 6 or distal edge, of the mesh device 2 of the present invention is opposite the medial edge 4. The mesh device further includes an adhesive surface 12 (referenced to but not shown), a non-adhesive surface 14, a superior edge 8, and an inferior edge 10.

(23) As illustrated in FIGS. 7-15, the superior edge 8 of the mesh device 2 is inserted onto the eye socket 22 below the eyebrow 34 and the mesh device bottom edge/inferior edge 10 is inserted onto the user's upper eyelid 30 above the inferior tarsus 32. The mesh device adhesive surface 12 adheres the mesh device 2 to the eye socket 22, and more specifically to the superior tarsus 30. The mesh device non-adhesive surface 14 does not contact the eye socket 22 nor the superior tarsus 30.

(24) In the accompanying photographs and drawings the mesh device 2 is positioned on the user's left eye with medial edge 4/nose corner edge 4 being placed on the left side of the user's face. However, it should be appreciated that the device is interchangeable for use on both the left and right sides of the user's face. When using the mesh device on the right eye, the reference numerals 4 and 6 may be interchanged to depict that the medial edge/nose corner edge 4 of the present device is inserted onto the user's right facial area.

(25) As shown in the photograph labeled FIG. 15, the mesh device becomes concave when conforming to the eye socket. This in turn curves the lower portion of the mesh material forcing the eyelid down and making the device act like the corrugation in steal, adding strength to the device, while achieving its function to hold the eyelid in a closed position. The mesh device 2 upper material, superior edge, rolls convexly around the under brow and on the superior tarsus. The mesh device 2 lower material, inferior edge, assumes the contour shape of the eyeball giving the device curvature 36, holding the superior tarsus 30 in the closed position. See FIGS. 8, 9, 13, and 15.

(26) It is well known that adding curvature to a flexible surface adds strength and rigidity. Notable examples are making stiff cardboard from paper and Pringles potato chips stored in cans. Here, the tarsus eyelid patch achieves curves when affixed to the region of the eye sockets below the eyebrow and to the closed eyelid. When affixed, the tarsus eyelid patch is concave in the horizontal direction in the region between the eyebrow and the upper eyelid, and the eyelid tarsus patch is convex in the vertical direction over the closed superior tarsus.

(27) The union of a convex and a concave curves forms a hyperbolic paraboloid curve.

(28) A hyperbolic paraboloid surface gains strength and rigidity by balancing the compressive forces of the convex region with the tensile forces of the concave region. A hyperbolic paraboloid surface is characterized by having vertical parabolic cross sections and horizontal hyperbolic cross sections.

(29) Referring now to FIGS. 10 and 15, the convex region 31 and the concave region 33 are illustrated when the eyelid tarsus patch is affixed.

(30) The mesh device 2 may be made of two 1-ply material sheets of transpore plastic, hypoallergenic, adhesive, perforated, transparent, latex-free tape. Thou it would be molded as one piece, and could be made out of other perforated adhesive medical material. For example, the preferred embodiment of the present invention may be constructed from a 2-ply medical material of at least one of a mesh fabric material, a hypoallergenic plastic material, or a latex free tape material, all having an adhesive surface.

(31) As shown in photographs FIG. 3, FIG. 3, FIG. 8, FIG. 10, FIG. 13, and FIG. 15, the mesh device 2 is designed with angles so the corners of the eyes are exposed for comfort, and to add medicine when the eyelid is closed, as to be noninvasive to the eye opening. As illustrated in the FIG. 1A, FIG. 1B, FIG. 1D, and FIG. 3D, in an embodiment of the invention, the perforation or mesh of the thin material allows the user's eyelid, exterior skin on the superior tarsus, to breathe.

(32) In a preferred embodiment of the present invention, the mesh device 2 dimensions are 2.25 length1 height0.0135 thickness. Metric measurements may be 5.7 cm length2.5 cm height34 mm thickness. However, it should be appreciated that the measurements and dimensions may vary to adapt to a specific user's facial features. The material is easily cut for adjustments if needed. The adhesive holds strong, yet it allows the device to be easily removed.

(33) In application of the mesh device 2, the user centers it over the closed superior tarsus, as shown in FIG. 13 and FIG. 15. The user then lines up the device inferior edge 10 just above the center of the opening of the eye on the upper eye lid above the lash. The user then gently rub the device 2 onto the eyelid, around the radius of the eyeball and up into the socket 20 and over the under part of the eyebrow 34 adhering the device 2 to the superior tarsus 30. This application holds down the superior tarsus only, keeping the eye closed.

(34) FIGS. 9, 11, 14 illustrate a detailed profile view of the Tarsus Eyelid Patch device applied on the eye, displaying how the device functions to hold the eyelid closed, and how the device conforms to the eye socket and under brow, leaving the corners of the eye exposed, and being noninvasive to the eye opening or to the inferior tarsus.

(35) In the preferred embodiment of the present invention, the mesh device 2 will be packaged individually like a bandage which will make it possible to be used in rural areas and third world countries. The present invention is ideal for use by the military for treating eye injuries during combat. Each device is intended for one time use. It may be worn daily, but also may be worn at night while sleeping as in cases of chronic dry eye, lazy eye, stroke, and for general eye health.

(36) The device is affective to heal scratches and defects on the eyes surface, also to aid in healing after Lasik and or eye surgeries with a doctor's recommendation. The mesh device 2 of the present invention is ideal for the elderly and children, and if necessary is easily applied by a caregiver. The tarsus eyelid patch will be produced in various sizes for youths, adults, and for adaptation to all shapes and forms of eyes, due to varying facial characteristics and ethnicities. This device relieves unnecessary suffering.
