Abstract
An implantable artificial capsule and a method of implantation are provided. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending substantially orthogonal from the outer surface of the ring. Each arm has transcleral anchors for sutureless scleral fixation. Upon implantation of the implantable artificial capsule the arms are externalized trans-sclerally and atraumatically. The arms sit subconjunctivally. The implantable artificial capsule does not have any sutures for fixation and is suturelessly implanted in an eye, which is a major advantage as it significantly reduces complications during surgery and recovery.
Claims16
An implantable artificial capsule, comprising:
- a structure comprising an outer, closed perimeter, a central opening, and a continuous groove for accommodating at least a portion of an intraocular lens;
- and
- at least three haptic arms, wherein prior to implantation, at least one haptic arm of said at least three haptic arms is straight and extends at a substantially orthogonal angle from the outer, closed perimeter of the structure,
- wherein each haptic arm of said at least three haptic arms comprises only a single trans-scleral anchor for sutureless trans-scleral fixation upon implantation of the implantable artificial capsule in an eye, wherein each of said single trans-scleral anchors is located at a distal end of each of said at least three haptic arms to form a “T” shape.
