PROBLEM TO BE SOLVED: To provide a highly transparent collagengel molding having a desired shape for ophthalmology and a high deformation temperature, especially a collagengel molding for ophthalmology, such as contact lens, a shield for bandage use, a controlled release carrier for ophthalmology medicine. SOLUTION: This collagengel molding for ophthalmology is prepared by mixing chemical crosslinking agents in a soluble collagen solution and directly casting and holding the solution in a die having a desired shape. The collagen molding for ophthalmology has good transparency, and a deforming temperature thereof is at least highly by 5 deg.C than that of raw material collagen. This soluble collagen is the one selected from acid soluble collagen, aterocollagen, chemically modified aterocollagen, alkaline soluble collagen and chemically alkaline soluble collagen. The chemical agent is an aldehyde or epoxy compound. |
