The invention concerns an implant forming an intraocular lens comprising a central optical part, a globally circular outline, at least partly made of a flexible material and a haptic part, at said optical part periphery, made at least partially of a rigid material. Said implant has a single-piece structure. The implant rigid material is a shape modified by at least one process selected among chemical reactions and polymerisation reactions of the starting flexible material, for example based on PMMA-PHMA, cross-linked by adding a multifunctional agent such as diethyleneglycol dimethacrylate.
Implant formant lentille intraoculaire comportant une partie optique centrale, à contour globalement circulaire, au moins partiellement en matériau souple et une partie haptique, en périphérie de ladite partie optique au moins partiellement en matériau rigide. La structur dudit implant est monobloc. Le matériau rigide de l'implant est une forme modifiée par au moins une voie choisie parmi les réactions chimiques et les réactions de polymérisation du matériau souple de départ, par exemple à base de PMMA-PHMA, réticulés par ajout d'un agent multifonctionnel tel le dimédthacrylate de diéthyléneglycol.
