The present invention has a constitution, which is simple, and features outstanding reliability and economic efficiency, and enables handling and operation to be performed easily and with certainty when holding and folding a soft intraocular lens 3. A soft intraocular lens-folding device comprises a movable member 1 and a base member 2. The movable member 1 comprises an elastically bendable pair of legs 12a, 12b, and a common base 11 for connecting this pair of legs 12a, 12b. At the tips of the pair of legs 12a, 12b there is disposed lens-receiving portions 13a, 13b, and wall portions 14a, 14b. In the lens-receiving portions 13a, 13b, a soft intraocular lens 3 is set astride both legs. The wall portions 14a, 14b have the function of clamping a soft intraocular lens 3 set in the lens-receiving portions 13a, 13b. The base member 2 comprises a slide groove portion 21. This slide groove portion 21 is formed so as to allow the tips of the pair of legs 12a, 12b to penetrate and slide through, and, in addition, to narrow the gap of the pair of legs 12a, 12b in accordance with the extent of movement thereof.
L'invention concerne un dispositif simple, économique et fiable permettant d'effectuer simplement et facilement des manipulations de maintien et de pliage d'un cristallin artificiel (3) souple. Le dispositif de pliage de cristallin artificiel souple comporte un élément (1) mobile et un élément (2) de blocage. L'élément (1) mobile possède deux pieds (12a, 12b) pliables élastiquement, et une extrémité (11) de base commune reliant les deux pieds (12a, 12b). Les extrémités antérieures des deux pieds (12a, 12b) sont pourvues d'éléments de support (13a, 13b) de cristallin, et de parois (14a, 14b). Les éléments de support (13a, 13b) de cristallin reçoivent le cristallin artificiel (3) souple qui s'étend sur les deux pieds. Les parois (14a, 14b) servent à retenir entre elles le cristallin artificiel (13) souple placé sur les éléments de support (13a, 13b) de cristallin. L'élément de blocage (2) comporte une glissière (21). La glissière (21) est formée de sorte qu'on peut insérer par glissement les extrémités antérieures des deux pieds (12a, 12b) à l'intérieur de celle-ci, et que l'espacement entre les deux pieds (12a, 12b) diminue en fonction de l'étendue de ce déplacement.
