<p>A sight correcting intraocular implant of which at least the base (2) is made of a flexible and biocompatible material such as a hydrogel. The implant includes a haptic base suitable for positioning in the posterior chamber (9) of the eye either in front of the lens or in the phacocyst, as well as a central portion (5) projecting through the pupil (13) and correcting all the optical defects of the eye (far-sightedness, short-sightedness, astigmatism, old-sightedness and macular degeneration). Said implant extends into the anterior chamber (14) at a certain distance from the corneal endothelium and is sized according to the intrinsic resilience of the constituent material so that the implant can be folded in half and inserted through a small aperture in the eye and through the dilated iris. As a result, said implant can easily be positioned and centred on the optic plane simply by recontracting the pupil, whereafter it is allowed to return to its natural shape corresponding to its final shape after implantation.</p> |
