Abstract:
1. An intraocular lens (IOL) supporter adapted to be inserted into a capsular sac, wherein the intraocular lens supporter is a structural body having a closed ring shape configured so that a force is transferred to the intraocular lens due to movement of a zonule of Zinn, the intraocular lens supporter comprising: an outer circular face configured to come in direct contact with an inner surface of a capsular sac in at least one point when inserted into the capsular sac; and an inner circular face arranged opposite to the first face, the inner face comes in direct contact with a haptic portion of the intraocular lens, wherein the intraocular lens supporter is extended along an equatorial region of the capsular sac when inserted into the capsular sac and in a section where the structural body is cut along a virtual plane in a visual axis direction of an eye lens, the outer face is provided at a length as much as ¾ to 3 times of a length of a region where an zonule of Zinn is coupled to an outer surface of the capsular sac, the outer face has a first extended length from one end portion to another end portion in the section where the structural body of the outer face is cut along the virtual plane in the visual axis direction of the eye lens of 2 mm to 8 mm, the inner face has a second extended length from one end portion to another end portion on the section where the inner face is cut along the virtual plane in the visual axis direction of the eye lens, wherein the second extended length of the inner face is longer by 0.4 to 1 times that of the first extended length of the outer face, and the outer face has an anterior portion and a posterior portion corresponding respectively to an anterior capsule and a posterior capsule when inserted into the capsular sac divided by an equator (E) of the capsular sac, wherein the equator is a vertical direction relative to the visual axis direction of the eye lens.
