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 .
