specific Embodiment approach 1
[0011] Embodiment 1: In this embodiment, a hydrophilic shape memory hydrogel as an intraocular lens material is made of polymerized monomers and initiators; wherein the polymerized monomers are hydroxyethyl methacrylate, 2-benzene Oxyethyl acrylate, polyethylene glycol methacrylate and triethylene glycol diacrylate; the initiator is azobisisobutyronitrile; the amount of polyethylene glycol methacrylate accounts for the total mass of polymerized monomers The amount of triethylene glycol diacrylate accounted for 1.0% to 5.0% of the total mass of polymerized monomers; the total amount of 2-phenoxyethyl acrylate and hydroxyethyl methacrylate accounted for 70%~100% of the total mass of monomers, the mass ratio of 2-phenoxyethyl acrylate and hydroxyethyl methacrylate is 1:(3~9); the amount of initiator accounts for the total mass of polymerized monomers 0.1% to 1.0%.
specific Embodiment approach 2
[0012] Embodiment 2: This embodiment differs from Embodiment 1 in that the amount of polyethylene glycol methacrylate accounts for 10% of the total mass of the polymerized monomers. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0013] Embodiment 3: This embodiment is different from Embodiment 1 in that the amount of polyethylene glycol methacrylate accounts for 20% of the total mass of the polymerized monomers. Others are the same as in the first embodiment.
