An intraocular optic assembly can include a first lens, a first plurality of stanchions, a second lens, and a second plurality of stanchions. A central optic axis can extend through centers of the first and second lenses. The first plurality of stanchions can each extend a first distance between a first base end and a first distal end. The first lens can be connected with the first distal ends. The second plurality of stanchions can each extend a second distance between a second base end and a second distal end. The second lens can be connected with the second distal ends. Compression at the peripheries of the stanchions induces movement of the lenses apart from one other.

The purpose of the present invention is to provide an intraocular lens injector with which the tip side of a plunger can be finely formed while ensuring rigidity, and with which the occurrence of shaft deviation during contact with an intraocular lens can be effectively inhibited. A plunger (3) of this intraocular lens injector (1) is provided with: a tip-side shaft part (35) provided with an L-shaped section (36); a central shaft part (33) which is formed flat, and which is wider than the tip-side shaft part (35); and a part (40) to be restricted which is formed from the tip-side shaft part (35) to the central shaft part (33), and which protrudes from the flat surface at the central shaft part (33). Furthermore, an opening (70) in a main body (2) is provided with: a central opening (71) which is open in accordance with the shape of the central shaft part (33); and a restriction part (72) formed so as to protrude from the end surface of the central opening (71), in the thickness direction of the central shaft part (33), in accordance with the shape of the part (40) to be restricted. The part (40) to be restricted has a length in the axial direction which is set such that the part (40) to be restricted is restricted by the restriction part (72) in an interval from an initial position before the L-shaped section (36) begins to be in contact with a second lens support part (93) of an intraocular lens (90), to a position in which the L-shaped section (36) is in contact with the second lens support part (93).

Method of preventing capsular opacification and fibrosis utilizing an accommodative intraocular lens implant
09744029 · 2017-08-29 ·

A method of preventing capsular opacification and fibrosis utilizing an accommodative intraocular lens implant, which includes the steps of removing a cortex and nucleus of a natural lens containing a cataract from a lens capsule of an eye of a patient; applying a photosensitizer inside the lens capsule so that the photosensitizer permeates a portion of the lens capsule, the photosensitizer facilitating cross-linking of the tissue in the portion of the lens capsule; irradiating the portion of the lens capsule so as to activate cross-linkers in the tissue in the portion of the lens capsule, thereby damaging the remaining lens epithelial cells in the lens capsule with the irradiated light so as to prevent capsular opacification and fibrosis; and injecting a transparent polymer into the lens capsule of the eye in order to form an accommodative intraocular lens for replacing the cortex and nucleus of the natural lens.
