An ophthalmic device includes an optic including an optic axis and a closed-loop haptic structure coupled to the optic via a frame surrounding the optic, the closed-loop haptic structure including a closed loop extending from first and second attachment points to the frame. The closed loop includes a first hinge and a second hinge. The first hinge has a first section having a first component extending in a first angular direction, a second section having a second component extending in a second angular direction opposite to the first angular direction, and a first connecting section between the first section and the second section. The second hinge has a third section having a third component extending in the second angular direction, a fourth section having a fourth component extending in the first angular direction, the fourth section being connected to the second section to form the closed loop.

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.

An open, seal-less intraocular lens is disclosed herein. An example intraocular lens may include an annular substrate including an oil electrode disposed in or on an inner sidewall of the annular substrate to electrostatically manipulate a volume of electrowetting oil, an optical window coupled to the substrate, where a side of the optical window adjacent to the inner sidewall and the inner sidewall of the annular substrate define a region for constraining the volume of electrowetting oil, and a saline electrode coupled to the annular substrate, the saline electrode positionable within an aqueous humor of an eye upon implantation

A suspension system for suspending an intra-ocular lens in the lens capsule of an eye has one or more collapsible cavities formed in the suspension system, each having at least one opening communicating the interior of the cavity with fluid from the interior of the eye, wherein the walls of the cavity exhibit sufficient structural elasticity that they return to their habitual shapes after being compressed by external force.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye, including: a housing; a nozzle operatively coupled to the housing; a plunger at least partially and moveably disposed within the housing for driving the lens component; and a spring that applies a biasing force to the plunger.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye may include a housing. The apparatus may further include a plunger at least partially disposed in the housing, wherein the housing comprises an elongated portion and a viscoelastic soft tip at a distal end of the elongated portion, wherein the viscoelastic soft tip has a storage modulus of about 1 megapascal (MPa) to about 300 MPa and a loss module of about 1 MPa to about 300 MPa. The apparatus may further include a drive mechanism operatively coupled to plunger and configured to cause the plunger to translate in the housing. The apparatus may further include a nozzle operatively coupled to the housing through which the plunger delivers the lens component into the eye.

An ophthalmosurgical injector system includes an injector, which has a handpiece, a plunger, and a dispensing device; an intraocular lens, which has an optic body and two C-shaped haptic arms protruding therefrom; and a cartridge, in which the intraocular lens is received. The dispensing device has an inlet opening at the proximal end and an outlet opening at the distal end. When the plunger is moved forward, the intraocular lens is conveyed from the cartridge through the inlet opening to the outlet opening of the dispensing device. When the intraocular lens is held in the cartridge in a compressed and preloaded state, a subregion of each of the haptic arms bears on and covers the optic body. In a plan view, the optic body of the preloaded intraocular lens has a circular surface area with a diameter of at least 4.0 mm that is not covered by the haptic arms.

An intraocular lens (TOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.

An intraocular lens for insertion into a capsular bag of an eye comprises: an optic; and at least one plate haptic coupled to the optic by one or more flexible connecting members. The plate haptic with projections which are designed to engage the periphery of the capsular bag to center and fixate the intraocular lens within. The haptic includes a longitudinally rigid frame to resist deformation of the haptic.

A deformable intraocular lens (IOL) comprises a deformable optic, having an annular edge around its periphery, and at least two haptics, each having a proximal portion and a distal portion relative to the optic. Each haptic extends from a different position on the annular edge of the optic and can be compressed. The IOL further comprises at least one tab extending from the annular edge of the optic at a position different from the proximal portion of each of the haptics. The or each tab can adjust the folding characteristics of the IOL, which in turn can control the speed and orientation of the IOL on injection into a patient's eye and ensure greater reliability of desired injection.
