Abstract
A hook portion 4 is provided which is formed so as to extend from base portions 21a of the ciliary processes 21 along the outer surfaces of the ciliary processes 21 via anterior end portions 21b of the ciliary processes 21 to base portions 21c at the opposite side. A leg portion 3 extending from the hook portion 4 toward the visual axis C is connected to the hook portion 4, and a lens 2 to be mounted in the eye of the patient is supported by the leg portion 3. The lens 2 is held in the eye of the patient in a state where the hook portion 4 is hooked or fitted to the ciliary processes 21.
Claims7
An intraocularly-mounted object configured to be placed inside an eye on an outer surface of a base portion of a ciliary process which projects toward a visual axis of the eye, comprising:
- an intraocular lens having an axial line;
- a predetermined number of leg portions radially extending from the intraocular lens, each of the leg portions having a distal end and a proximal end connected to the lens;
- a predetermined number of hook portions each connected to the distal end of a corresponding one of the leg portions, the hook portions each having a substantially C claw-like shape defining a ciliary process contacting-surface formed by an upper portion, a lower portion and an intermediate portion between the upper portion and the lower portion, the upper portion and the lower portion projecting away from the axial line while the intermediate portion projecting toward the axial line so as to form a space for accepting the base portion of the ciliary process as the axial line is being aligned with the visual axis when the intraocularly-mounted object is placed in the eye,
- wherein each of the hook portions further comprises:
- a plurality of unit hook portions disposed adjacently in an arc at a predetermined intervals about the axial line;
- and
- at least one connection portion that connects the plurality of unit hook portions together.
