A method for making an intraocular implant with a soft lens by means of a mould having two portions (14 16) arranged on either side of a plate (20), made for example from PMMA, comprising a central aperture. The material (32) for forming the lens portion, e g. an acrylic, is placed in the central mould cavity. After opening the mould, the plate (20) and optionally the lens portion (32) are machined to provide the haptic and the lens respectively.
L'invention concerne un procédé de réalisation d'un implant intraoculaire à optique souple. Le procédé consiste à partir d'un moule dont les deux parties (14 et 16) sont disposées de part et d'autre d'une plaque (20), par exemple en PMMA, qui comporte un orifice central. On dispose dans la cavité centrale du moule le matériau (32) destiné à constituer la partie optique. Il s'agit par exemple d'un acrylique.
