Title: (DE) INTRAOKULARE REFRAKTIONSLINSE
(EN) INTRAOCULAR REFRACTIVE LENS
(FR) LENTILLE REFRINGENTE INTRAOCULAIRE
Abstract: front page image
(EN) An intraocular lens surgically positioned in the anterior chamber and to be used in addition to the natural lens to correct the refraction. The lens is fixated by iris stromal support, comprising an optical portion of inner concave and outer convex shape and a side support portion which has one or more pairs of pincerlike extensions for holding a portion of iris tissue. The design provides safe clearance away from the vital structures both anteriorly and posteriorly. This technique of stromal iris support permits full pupil motility. Lack of any postoperative decentration allows the system to be used for myopia, hyperopia, presbyopia or astigmatism. A non-transparent, light-impermeable ring may be incorporated to prevent glare or edge effects. The lens provides high predictability of the precalculated optical power.
(FR) Lentille intraoculaire positionnée par chirurgie dans la chambre antérieure devant être utilisée en complément de la lentille naturelle de façon à modifier la réfraction. La lentille est fixée en utilisant comme support le stroma irien, comprenant une partie optique de forme intérieure concave et de forme extérieure concave et une partie du support latéral possédant une ou plusieurs paires de prolongations en forme de pinces permettant de maintenir une partie de tissu irien. La configuration permet d'assurer un espacement sans risque par rapport aux structures vitales antérieure et postérieure. Cette technique faisant appel à un support utilisant le stroma irien permet une mobilité totale de la pupille. L'absence de toute décentration post-opératoire permet d'utiliser le système pour la myopie, l'hypermétropie, la presbytie ou l'astigmatisme. Un anneau non transparent imperméable à la lumière peut être incorporé de façon à éviter l'éblouissement ou les effets de bord. La lentille assure une prévisibilité élevée du pouvoir optique précalculé.
