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.
Claims15
Lens implant (12) for a placement into a posterior portion (3b) of an intracapsular space (3) after removal of a native lens body (2) from a lens capsule 13 of an eye,
- wherein the lens implant (12) is formed of one part and manufactured from suitable non-cellular structural transparent material,
- wherein the lens implant (12) is dimensioned to keep an anterior portion (3a) of the intracapsular space (3) free of non-cellular structural material,
- wherein the lens implant (12) is devoid of any further part formed by non-cellular structural material or components thereof,
- wherein the lens implant (12) comprises at most 40% of a volume of the native lens body (2), which was removed or of the volume of a native lens body (2) with an average size, and
- wherein the lens implant (12) has a convex posterior surface with a curvature which is shaped to fit a posterior inner surface (13b) of the capsule (13).
Capsule filling composition (15) for use in intraocular surgery for filling an intracapsular space (3) after removal of a native lens body (2) from a lens capsule 13 of an eye,
- wherein the filling of the intracapsular space (3) accompanies the introduction of a lens implant (12) manufactured from suitable non-cellular structural transparent material into a posterior portion 3 (b) of the intracapsular space (3) replacing a posterior portion (2b) of the lens body (2) and wherein the volume of the lens implant (12) amounts to at most 40% of the volume of the lens body (2),
- wherein the introduced volume of the filling composition (15) together with the volume of the implant (12) provides for reconstitution of a volume essentially corresponding to the volume of the native lens body (2), which was removed or of the volume of a native lens body (2) with an average size and
- wherein the capsular filling composition (15) is of an aqueous composition and is devoid of non-cellular structural material or components thereof for replacement of lens fibers.
