20210128293 · 2021-05-06 ·

A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.

Two-part accommodating intraocular lens device

A two-part accommodating intraocular lens (IOL) device for implantation in a capsular bag of a patient's eye. The IOL device includes a primary lens assembly and a power changing lens. The primary lens assembly includes a fixed lens and a peripherally disposed centration member. The centration member has a circumferential distal edge and a first coupling surface adjacent the circumferential distal edge. The power changing lens has an enclosed, fluid- or gel-filled lens cavity and haptic system disposed peripherally of the lens cavity. The haptic system has a peripheral engaging edge configured to contact the capsular bag and a second coupling surface. The first and second coupling surfaces are in sliding contact with one another to permit movement of the power changing lens relative to the primary lens assembly and also to maintain a spaced relationship between the fixed lens and the lens cavity during radial compression of the power changing lens.

MEMORY MATERIAL FIXATION DEVICE
20210161652 · 2021-06-03 ·

A memory material fixation device is provided that is suitable for tissue fixation, including intraocular fixation, and has a main body that can be compressed elongated or shortened within a delivery system and a collapsible catch-shaped end that can pass through a material in a collapsed state to catch on an opposite surface of the material when in an expanded state to achieve fixation. A delivery system can hold the memory material fixation device in a constrained fashion, compressing the collapsible catch-shaped end in the collapsed state. Once a target structure has been traversed by the delivery system and a hole made in a material of the structure, the collapsible catch-shaped end of the fixation device is deployed from the delivery system, whereupon the collapsible catch-shaped end of the fixation device expands to take its neutral-stress shape of the expanded state to achieve fixation.

10973624 · 2021-04-13 · ·

A device for supporting an intraocular lens in an eye. The device has a lens support structure having an inner perimeter surface defining, at least in part, a central opening. When implanted, light may pass through the central opening towards the retina. The device has at least three fixation arms, each having an origin portion coupled to the lens support structure and a terminal portion comprising an anchor for trans-scleral fixation of the device. Prior to implantation, at least one fixation arm is biased towards a folded configuration and has a bend between the origin portion and the terminal portion. The origin portion extends away from the lens support structure and the anchor of the terminal portion is positioned over or under at least one of a portion of the lens support structure and a portion of the central opening. Related tools, systems, and methods are provided.
