ABSTRACT:
Eye wall anchored fixtures each including at least one elongated anchor member for driven lengthwise insertion into an eye's eye wall in a transverse direction to its thickness for supporting an intraocular device in the eye's vitreous cavity. Fixtures are preferably anchored in circumferential incisions in a human adult eye's pars plana preferably 3.5 mm posterior to its corneal limbus, and perpendicular to a circumferential incision. The fixtures are either generally L-shaped with a single elongated anchor member designed for withdrawal from an eye wall or self-anchoring thereinto, or generally T-shaped with a pair of oppositely directed self-anchoring elongated anchor members for sealing a throughgoing incision. Intraocular devices can be designed for intraocular drug delivery, for acquiring intraocular physiological measurements, and the like.
