    摘要: The invention relates to a method of making an intraocular implant having a flexible lens. The method includes in using a mold having two parts (12) and (16) which are disposed on either side of a plate (20), e.g. made of PMMA, which plate includes a central orifice. The material (32) that is to constitute the lens portion is disposed in the central cavity of the mold. This material may be an acrylic, for example. After unmolding, the plate (20) is machined to make the haptic, and optionally the part (32) is machined to make the lens.
