Abstract

L'invention constitue une amélioration de la lentille intraoculaire monobloc souple (420) dans la mesure où sa région de transition (422) présente une forme arrondie entre la partie corps (424) de la lentille et les parties constituant l'ailette de fixation (426) de la lentille intraoculaire (420). La région de transition (422) à forme arrondie est réalisée par un cordon à section concave (428). Cette partie en cordon à section concave (428) sert à consolider l'angle d'insertion au niveau de l'intersection entre la partie corps (424) de la lentille et la partie haptique en forme d'ailette (426). La partie en cordon à section concave (428) est ajoutée à la zone de jointure de la lentille pour diminuer la contrainte qui s'exerçait sur la lentille intraoculaire (420) dans l'état antérieur de la technique où la jointure était en forme d'arête rentrante vive. Le rayon préconisé pour la concavité de la section du cordon de la région de transition (422) est compris entre 0,01 et 0,25 mm. La lentille intraoculaire monobloc (420) dont la région de transition (422) est constituée d'un cordon à section concave (428) entre l'élément optique (424) et l'haptique en forme d'ailette (426) est réalisée de préférence par moulage monobloc (440) pour mieux garantir le respect du rayon de concavité de la région de transition (422).
