  • the guide introduction section 32, the guide narrow section 33, the guide wide section 34, and the sliding stop projection 36 are held by the lens holding section 50 by the movement of the cap 40 with respect to the base 10. It is configured as a guide hole 31 for bending the IOL 1, but the other guide narrow part 33 a, wide guide part 34 a and sliding stop projection 36 a opposite to each other By moving the cap base engaging portion 44 over the sliding stop projection 36a and moving it to the wide portion 34a. Without bending the IOL 1 held by the lens holding portion 50, Cap 40 can be removed from base 10. Therefore, the surgeon himself or his assistant can arbitrarily bend by using a forceps injector or the like separately.
  • thermoplastic resin that can be generally molded into a mold, such as polypropylene, polyethylene, or polystyrene, may be used.
  • the IOL 1 can be arranged without difficulty in the lens holding section 54.
  • the interval S 3 is set to IOL 1 It is only necessary that the diameter is sufficiently smaller than the diameter of the optical part 2 of the optical element.
  • S3 is larger than the diameter of the optical unit 2 of the IOL 1, the IOL 1 cannot be held between the lens holding units 54.
  • the lens is tilted while the optical part 2 of the IOL 1 is tilted.

  • the interval S 1 is used to prevent the risk of the I ⁇ L 1 jumping out or falling off during the placement of the IOL 1, the assembly of the cap 40 to the base 10, during distribution, or during bending, etc. It is preferable that (the diameter of the optical section 2 of IOL 1 ⁇ S 1 + S 2) and that the diameter is substantially the same as or slightly smaller than the diameter of the optical section 2 of IOL 1.
  • the interval S2 is 3 mm or less, preferably 1 mm or less, and more preferably 0.6 mm or less, in consideration of the ease of arrangement of the I 1L 1 and the retention.

Abstract

L'invention concerne un récipient de distribution pour lentille intraoculaire permettant de maintenir facilement et de manière stable ladite lentille intraoculaire sur une partie porte-lentille. Ledit récipient de distribution comprend une base, un bouchon et la partie porte-lentille dotée d'une paire de parties de serrage disposées sur la base, ces parties de serrage étant disposées afin de s'opposer par l'intermédiaire d'une partie de séparation séparant lesdites parties de serrage d'une distante permettant de maintenir la lentille intraoculaire sur celles-ci. Une partie de maintien et de coopération stable fait saillie vers l'intérieur à partir de la surface intérieure du bouchon et l'extrémité de la partie de maintien et de coopération stable est chanfreinée afin de former une partie d'entrée. La lentille intraoculaire est disposée entre les parties de serrage de lentille, et la partie d'entrée est amenée en contact avec la partie porte-lentille lorsque le bouchon est installé sur la base afin réduire la distance de la partie de séparation. En conséquence, le récipient est caractérisé en ce que la lentille intraoculaire disposée entre les parties de porte-lentille peut être maintenue sans être comprimée et sans tomber.
