The invention discloses an implantable myopia lens, comprising a lens body and a plurality of sheet-shaped support arms, cut and formed along the edge of the lens body. The angle between the plane of the support arms and the plane of the lens body is between 10 and 20 degrees, making the whole of the lens a spheroid. A transparent light guide zone is arranged on the lens body. The lens body and the support arms are all made of a same hydrophilic polyacrylate material. The invention also discloses a preparation method of the implantable myopia lens. The support arms of this invention are bendable, and the bending angle thereof is automatically adjusted according to the contour of a human eye when the lens is implanted therein. The lens of the same model can be implanted into human eyes of different sizes. The lens is better fit to human eyes and more comfortable because the connections between the support arms and the lens body are thin and short, the support arms bend more easily, and the lens adjusts automatically in size. The lens material has a high refractive index and a small thickness, and the hydrophilic polyacrylate material is highly elastic, making the lens easy to be implanted into the human eye.
