An intraocular lens (2) with which the natural lens of the eye (1) is replaced in connection with, for example, a cataract operation. By using a bifocal intraocular lens which has advantageously two different focal distances (8, 9), two images are produced on the retina (3), one of the images being sharp at close distance (7, 7') and the other being sharp at long distance (6, 6'). The brain emphasizes the desired image. |
