Claims
- 1. A scleral expansion segment comprising an arched rod having two free ends connected by a bridge, the arched rod being designed to be placed on the sclera perpendicular to the ciliary body and being characterized in that the free ends of said rod have a spatula shape wider than a diameter of said bridge, so as to constitute wide support bases.
- 2. The segment according to claim 1, characterized in that the bases have a radius of curvature R1 corresponding to that of the sclera perpendicular to the ciliary body, whereas the bridge has a radius of curvature R2 less than R1.
- 3. The segment according to claim 2, characterized in that it defines a multitude of perforations.
- 4. The segment according to claim 2, characterized in that it is coated with a biocompatible synthetic material with a porous surface.
- 5. The segment according to claim 4, characterized in that it consists of a core of formable material with shape memory, sunk in a layer of soft material.
- 6. The segment according to claim 4, characterized in that it has an internal canal intended for placement of a core, the nature and strength of which can be chosen in order to adjust the effect of the scleral expansion segment.
- 7. The segment according to claim 6, characterized in that the core consists of an injectable product.
- 8. The segment according to claim 7, characterized in that it is made in two parts, a first part and a second part, which interlock with each other.
- 9. The segment according to claim 8, characterized in that the first part includes a base equipped with a female attachment means, while the second part includes the other base combined with the bridge, the free end of which contains a male attachment means.
- 10. The segment according to claim 9, characterized in that the two parts contain means for preventing any rotation relative to each other.
