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.
