The present invention provides a shape memory orbital bone implant and a preparation method thereof. The shape memory orbital bone implant is made of a degradable shape memory polyurethane composite material; the temporary shape of the shape memory orbital bone implant is a flat shape and the initial shape of the shape memory orbital bone implant matches a shape of a defect of an orbital bone; andthe shape memory orbital bone implant is suitable for being irradiated by a light source with a wavelength range of 510-535 nm and automatically expands from a temporary shape to the initial shape. Compared with the prior art, the shape memory orbital bone implant has a shape memory effect. The orbital bone implant can be flattened by shaping before implantation, which can reduce pains caused topatients during implantation and can ensure the smooth progress of the implantation operation. After the orbital bone implant reaches the affected part of the human body, the shape of the shape memoryorbital bone implant can b
