Abstract
A tensioning device for attaching to the anterior capsule of an eye, and accommodative intraocular lens systems employing the device. The tensioning device includes a biocompatible, elastically reconfigurable ring for restoring at least a portion of the anterior capsule centripetal forces lost by capsulorhexis. The tensioning device also includes a plurality of penetrators configured for attaching the ring to the anterior capsule. The plurality of penetrators is biocompatible with the eye and partially embedded in a part of the ring configured for facing the anterior capsule.
Claims14
A tensioning device for external attachment to an anterior capsule of an eye and placement proximal to and radially outward with respect to an anterior capsulorhexis site thereof, the device comprising:
- a substantially axisymmetric, biocompatible, elastically reconfigurable tensioning ring for restoring at least a portion of anterior capsule centripetal forces lost, or to be lost, by the capsulorhexis;
- and
- a plurality of biocompatible penetrators used to attach the tensioning ring to the anterior capsule, wherein the plurality of penetrators is partially embedded in a part of the tensioning ring for facing the anterior capsule,
- wherein the penetrators are oriented to penetrate the anterior capsule when the tensioning ring is attached to the anterior capsule by insertion of the penetrators into the anterior capsule from a direction outside of the eye and towards an interior of the eye, and wherein the tensioning ring is configured to be placed closer to an opening created by the capsulorhexis than to an equator of the anterior capsule.
