Scleral implants for treating presbyopia and methods for implanting the same

摘要

A scleral implant includes a body with a central portion and a pair of end portions. Each of the portions has a parametrical dimension. The parametrical dimension of the central portion is greater than the parametrical dimensions of each of the end portions. Accordingly, when the implant is positioned within an incision in the sclera of an eye, the inward force of the incision on the central portion of the body frictionally retains the implant within the incision. The scleral implant may include one or more enlarged portions each having a parametrical dimension greater than the parametrical dimension of the central portion. The implant may structure for engaging with sides of the incision such that extrusion of the implant from the incision is mitigated. The structure may include a plurality of dimples or a plurality of nodes formed in the surface of the body. Each of these structures forms a discontinuity or a purchase on the body to which post-operative cellular and fibrous growth may attached.
