Title (EN) POSTERIOR CHAMBER INTRAOCULAR LENS
(FR) LENTILLE INTRAOCULAIRE SITUEE DANS LA CHAMBRE POSTERIEURE
Abstract:
(EN) An intraocular lens (10, 110) for implanting in the posterior chamber of an eye after extracapsular cataract extraction includes a flexible filament ring (24, 124) spaced from a lens body (12, 112) to engage the posterior capsule (134) and adhere thereto due to fibrosis attachment forming a barrier enclosing an optical zone behind the lens body (12, 112) to prevent migration of crystalline, epithelial cells from the perimeter of the posterior capsule (134) to the optical zone thereby preventing opacification.
(FR) Une lentille intraoculaire (10, 110), destinée à être implantée dans la chambre postérieure d'un oeil après l'extraction d'une cataracte extracapsulaire, comprend un anneau de filament flexible (24, 124) espacé d'un corps de lentille (12, 112) de manière à s'engager dans la capsule postérieure (134) et y adhérer grâce à une fixation pour fibrose formant une barrière qui entoure une zone optique derrière le corps de lentille (12, 112) pour empêcher la migration de cellules épithéliales cristallines depuis le périmètre de la capsule postérieure (134) jusqu'à la zone optique, afin de prévenir l'opacification.
