A lenticular capsule-expanding device is arranged in a lens capsule in a cataract surgery, etc. The device includes a front supporting section to be arranged in contact with an inner surface of an anterior capsule, the front supporting section, a rear supporting section to be arranged in contact with an inner surface of a posterior capsule, the rear supporting section being arranged behind the front supporting section, and a connecting section that connects the front and rear supporting sections in a manner as to have an urging force for separating the front and rear supporting sections in a separating direction. By the urging force of the connecting section, the front supporting section presses against the inner surface of the anterior capsule and the rear supporting section presses against the inner surface of the posterior capsule. |

1. A lenticular capsule-expanding device to be arranged in a lens capsule, comprising:
a front supporting section to be arranged in a manner as to come into contact with an inner surface of an anterior capsule of the lens capsule, the front supporting section allowing light to pass through rearward; a rear supporting section to be arranged in a manner as to come into contact with an inner surface of a posterior capsule of the lens capsule, the rear supporting section being arranged so as to be opposed to the front supporting section and allowing light to pass through rearward; and a connecting section that connects the front supporting section and the rear supporting section in a manner as to have an urging force for separating the front supporting section and the rear supporting section in a separating direction, wherein, by the urging force of the connecting section, the front supporting section presses against the inner surface of the anterior capsule and the rear supporting section presses against the inner surface of the posterior capsule, wherein the connecting section includes a bending portion capable of being bent radially outward of the front supporting section and the rear supporting section, wherein an intraocular lens is arranged between the front supporting section and the rear supporting section, wherein the intraocular lens includes an optical section made of a lens and a plurality of arm sections provided at a peripheral portion of the optical section, wherein one end portion of each of the plurality of arm sections is connected to the peripheral portion of the optical section, and the other end portion of each of the plurality of arm sections is engaged with the connecting section, the other end portion being positioned rearward of the one end portion, and wherein when the other end portions of the arm sections are moved in the approaching or separating direction depending on a degree of radial contraction or expansion of the connecting section, the optical section moves between the front supporting section and the rear supporting section in a front-back direction. |
