Abstract
The invention concerns an intraocular lens implant for placement into an intracapsular space of a lens capsule of an eye and a composition, kit and methods related to the lens implant. The lens implant is designed for a placement into a posterior portion of the intracapsular space after removal of a native lens body and has a convex posterior surface. The lens implant is formed of one part and is manufactured from a suitable transparent non-structural cellular material. This keeps an anterior portion of the intracapsular space free of the implant which is dimensioned to comprise at most 40% of a volume of the native lens body.
Claims17
A kit consisting of a lens implant for a placement into a posterior portion of an intracapsular space after removal of a native lens body from a lens capsule of an eye and a capsule filling composition for use in intraocular surgery for filling the intracapsular space after introduction of the lens implant
- wherein the lens implant is formed of one part and manufactured from a suitable transparent non-cellular structural material, wherein the non-cellular structural material is selected from the group consisting of:
- a silicone, a hydrophobic acrylic material, a hydrophilic acrylic material, a hydrogel, and a collagen polymer,
- wherein the lens implant is dimensioned to keep an anterior portion of the intracapsular space free of non-cellular structural material and subunits thereof,
- wherein the lens implant is devoid of any further part formed by the non-cellular structural material or subunits thereof,
- wherein the lens implant comprises at most 40% of a volume of the native lens body, which was removed or of the volume of a native lens body with an average size, and
- wherein the lens implant has a convex posterior surface with a curvature which is shaped to fit a posterior inner surface of the capsule,
- wherein the volume of the filling composition and the volume of the lens implant are such as provide for reconstitution of a volume essentially corresponding to the volume of the native lens body which was removed or of the volume of a native lens body with an average size and
- wherein the capsular filling composition is of an aqueous composition and is devoid of said non-cellular structural material or subunits thereof.
