Abstract: A reinforcement component for a high-myopia posterior sclera, including a support pad and support strips connected to the support pad. The support pad is provided with an avoidance portion at an edge thereof and through-holes for blood vessels to pass through. Each through-hole is in a form of an ellipse with a long axis parallel with an edge of the avoidance portion and a short axis. The avoidance portion and the through-holes are provided such that even if the size of the through-hole is compressed by the avoidance portion, the through-hole is elliptical with its long axis set along the edge of the avoidance portion, the size of the through-hole can be expanded. The ratio of the long axis to the short axis of the through-hole is not less than 8/7, and not more than 20/9, which facilitates the blood vessels to pass through the through-hole.

Abstract: A foldable pressing-type balloon structure (10), comprising a balloon body (100) used for arrangement in the Tenon capsule and a drainage component (200) capable of being closed automatically. The balloon body (100) is formed with a balloon cavity used for supplying normal saline or air; the balloon body (100) has a planar first surface (110) and a curved second surface (120); the height of the balloon body (100) along the first surface (110) is 0.2-2.0 cm; the drainage component (200) is connected to the second surface (120) of the balloon body (100) and communicated with the balloon cavity. The foldable pressing-type balloon structure (10) is implanted under the Tenon capsule, and a break is sealed by pressing by filling the inside of the balloon body (100) with a medium.

Abstract: The present invention relates to a foldable capsular vitreous body (FCVB), and its mold design, method for manufacturing, product appearance, and drug delivery property and so on. A mold for molding a foldable artificial vitreous body comprises an upper mold (1), a lower mold (2) and a core (3). The core (3) is disposed between the upper mold (1) and the lower mold (2) and is connected with a drainage-tube pin connected with an injection channel (4). Heating holes (6) are disposed in the upper mold (1) and/or the lower mold (2). Material is injected to the mold and is heated to vulcanize to mold vitreous body. The FCVB is adapted to be injected with any harmless medium and can be used as a delivery vehicle inside or around the eye ball. The size or shape of the FCVB can be changed depending on the different implant site.

Abstract: A capsular bag for the artificial vitreous body is made up of a material selected from the group consisting of polysiloxane, polyurethane styrene triblock copolymer thermoplastic elastomers, hydroxyethyl methacrylate, polyvinyl alcohol, poly (lactide-co-glycolide, and hyaluronic acid ester. A method for manufacturing the capsular bag for the artificial vitreous body is performed by dip-molding, effectively improving the smoothness of the inner surface of the capsule. An eye die is dipped into a gel solution until the surface adsorbs the gel, and then lifted, repeating 3-6 times. The dipped eye is hardened into shape. A shaped spherical outer capsule is peeled out of the eye die. The capsular bag for the artificial vitreous body has high biocompatibility and excellent flexibility.
