Abstract

In the connection zone, the portion of the haptic part connected to the optic part is situated on the edge of the optic part. The optic part consists of a flexible lens which can be folded or rolled upon insertion of the implant into the anterior chamber. The haptic part has a general form of the number 2 and has an upper free end, a bend, and a lower free end. In the connection zone, the connection between the optic part and the haptic part is rigid.

Claims

1. Anterior chamber intraocular implant for treating ametropias of a phakic eye, comprising an optic part, consisting of a flexible lens which can be rolled or folded upon insertion of the implant into an anterior chamber of the eye, and a flexible haptic part for maintaining the optic part in the anterior chamber, wherein the haptic part has bearing points configured to lodge in the iridocorneal angle,

wherein the haptic part comprises a bend, a lower free end, and an upper free end and has the general shape of the number 2;

and has three bearing points, one at the bend and one at each of the free ends;

wherein the haptic part is connected to an edge of the optic part at a zone of connection;

wherein in the connection zone, the connection between the optic part and the haptic part is rigid, whereby the optic part is maintained stable in a plane perpendicular to the optic axis of the eye;

wherein the haptic part is curved between the bend and a free end, said curve has a concave side and a convex side;

wherein the connection zone is on the concave side of the curve and is a zone of tangency between the optic part and the haptic part.

2. Implant according to claim 1, wherein the haptic part comprises a rigid portion at the connection zone to ensure rigid connection to the optic part.

3. Implant according to claim 1, wherein the connection zone is between the bend of the haptic part and the upper free end.

4. Implant according to claim 1, wherein the lens is made from a material selected from the group consisting of acrylic material, silicone and HEMA.

5. Implant according to claim 1, wherein the haptic part is made from PMMA.

6. Anterior chamber intraocular implant for treating ametropias of a phakic eye, comprising an optic part, consisting of a flexible lens which can be rolled or folded upon insertion of the implant into an anterior chamber of the eye, and a flexible haptic part for maintaining the optic part in the anterior chamber, wherein the haptic part has bearing points configured to lodge in the iridocorneal angle,

wherein the haptic part comprises a bend, a lower free end, and an upper free end and has the general shape of the number 2;

and has three bearing points, one at the bend and one at each of the free ends;

wherein the haptic part is connected to an edge of the optic part at a zone of connection and has a cradle whose edge is substantially circular so as to be in contact with the lens over the connection zone;

wherein in the connection zone, the connection between the optic part and the haptic part is rigid, whereby the optic part is maintained stable in a plane perpendicular to the optic axis of the eye; and

wherein the haptic part is curved between the bend and a free end, said curve has a concave side and a convex side;

wherein the connection zone is on the concave side of the curve.

7. Implant according to claim 6, wherein the haptic part comprises a rigid portion at the connection zone to ensure rigid connection to the optic part.

8. Implant according to claim 6, wherein the connection zone is between the bend of the haptic part and the upper free end.

9. Implant according to claim 6, wherein the lens is made from a material selected from the group consisting of acrylic material, silicone and HEMA.

10. Implant according to claim 6, wherein the haptic part is made from PMMA.
