ABSTRACT:
An intraocular lens which can be deformed substantially so as to be inserted through a very small incision in the eye. The intraocular lens has an optical element (10) made from a flexible membrane (18) and is filled with a fluid optical medium. Attached to the optical element is a bladder (12) into which the fluid medium from the optical element (10) can be shunted. When inserting the intraocular lens the fluid medium is first shunted from the optical element (10) into the bladder (12); this reduces the size of the optical element (10). With the optical element (10) in this state of reduced size it is passed through the cornea through a small incision. With the optical element (10) now inside the eye and the bladder (12) outside the eye, the fluid medium is shunted back from the bladder (12) into the optical element (10). This reduces the size of the bladder (12) allowing also it to be passed through the small incision. In this way the whole intraocular lens is passed into the eye through a small incision.
