Abstract: According to embodiments, a membrane with a flat or curved surface is provided for protection of intraocular tissues. The membrane can be used to cover the cornea for protecting corneal endothelial cells, to cover the anterior and posterior surface of the iris, or to cover the surface of the posterior capsule for separating the intraocular tissues. The membrane has a layered structure, which is composed of a collagen and a hydrophilic biopolymer or an organic polymer material. In particular, the membrane has high transparency and high water retention in a wet state.

Abstract: An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.
