An accommodating intraocular lens. The lens includes a substantially rigid anterior member having an extrusion aperture. First transparent deformable material is disposed anterior to the posterior side of the anterior member. Second transparent deformable material is disposed adjacent the posterior surface of the first material the second material having a different degree of deformability than the first material and having an index of refraction different from the index of refraction of the first material. This forms a refractive deformable interface between the body of first material and the body of the second material. Force applied to the second material causes that material to be extruded through the aperture so as to form a curved refractive interface with the body of first material. A method for installation of the accommodating intraocular lens is also provided.
