Abstract: A length or strand of resilient material is formed into a continuous ring having multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed with elongated straight sides joined by corner portions which are enlarged in directions transverse to the length dimension of each adjacent side. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting section that forms a gap for receiving the tissue. Each side of the ring extends from a bottom section of one corner to a top section of an adjacent corner. When the ring is deployed, the tissue is captured in the gaps at the corners of the ring and also is engaged along each side as that side transitions from a position situated below the tissue to a position situated above the issue.

Abstract: A strand of resilient material has multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed as a continuous ring with straight sides joined by corner portions. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting arc of the strand to form a gap receiving for receiving the tissue.

Abstract: A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a first end and a second end that each have an indent. The ring includes an adhesive that extends into the indents and attaches the first end to the second end.

Abstract: Disclosed are an intraocular lens (IOL) push rod, an IOL cartridge, multiple embodiments of an IOL cartridge housing, and a method for folding an IOL for insertion into an eye during ocular surgery. The distal end of the push rod is contoured to apply force to a substantial portion of the perimeter of an IOL to advance the IOL through a bore of the cartridge. Two hinges couple flanges on the IOL cartridge to a central portion that supports an IOL when protected by a cover for an extended storage time. The IOL cartridge has a locking element that engages a cartridge housing or IOL inserter. Each cartridge housing accepts the IOL cartridge with the IOL in an unfolded state. The cartridge bore is unobstructed and is tapered to fold one side of the IOL over the other as the IOL is advanced through the bore and into an eye.

Abstract: An intraocular lens (IOL) inserter and method of use ensure that an artificial intraocular lens is controllably ejected from a cartridge and into a patient's eye by using successive, predefined detent positions. One embodiment has a distal pivotal portion that can be pivoted to a desired angle as a mover advances the IOL into the eye. A detent controls the motion of the mover. In one embodiment, the detent includes a longitudinally extending component with a plurality of stair steps, so that a face of each stair step engages the housing at each different predefined detent position. Other embodiments include at least one orifice in the housing, so that when the orifice is aligned with a pin or protrusion, it engages the orifice to define a detent step. Another embodiment includes a spring-loaded collar that biases a pin into a predefined detent step.

Abstract: An apparatus for controllably delivering an IOL into the eye of a patient is disclosed. The device is configured for convenient and reliable positioning of a plunger rod assembly at different stages of the IOL injection procedure, such that various aspects of the insertion procedure can be performed precisely and reliably by a user of the device. The present invention may include a latch pin and a latch finger configured for engagement with the latch pin to prevent proximal lateral movement of the plunger rod assembly so that the intra-ocular lens may be accurately positioned within the eye. The device assists the user during the procedure by accurately and consistently positioning the plunger rod assembly prior to ejection of the folded or rolled IOL from the insertion device.

Abstract: Two elongated side plates are pivotally connected together for rotation about an axis extending lengthwise of and between the side plates. Thin, elongated necks extend distally from the side plates to a pair of jaws configured to grasp and release a foldable intraocular lens. The necks connecting the jaws to the side plates are shaped such that adjacent points are substantially intersected by the axis, with such intersection point located to be positioned at approximately the corneal incision during a lens implantation procedure. Thus, with the jaws positioned interiorly of the lens capsule, the jaws can be swung between open and closed positions without unnecessary stretching of the corneal incision.

Abstract: Elongated generally horizontal blades are spaced apart vertically and have proximate handle end portions and distal grasping end portions. By manipulation of the handle end portions, the grasping end portions can be brought together into clamping engagement. The lower grasping end portion is return bent and includes a marginal portion offset laterally from the remainder of the lower blade. The upper grasping end portion is movable downward alongside the lower blade so as to engage against such laterally offset marginal portion of the lower grasping end portion. The composite forceps-type instrument is useful for implanting intraocular lenses during cataract surgery, particularly for positioning the superior haptic of an intraocular lens in a lens capsule.

Abstract: The tool and method for preparing for insertion into an eye an intraocular lens formed of a compressible material includes an elongated hollow chamber with an inlet end and an outlet end. An intraocular lens formed of a compressible material is extruded to a smaller size that fits in the elongated chamber by a compresser which includes an outlet adapted to be aligned with the inlet end of the elongated chamber. The extruded intraocular lens is pushed through the elongated chamber from the inlet end through to the outlet end.

Abstract: An intraocular lens having one or more flexible haptic support loops connected to an optic. Each haptic support loop includes a first segment connected to the optic and extending therefrom at an acute angle relative to the optic periphery, a second segment extending from the first segment in an arc having at least one radius of curvature smaller than the radius of the optic and at least one radius of curvature on the side of the haptic opposite the acute angle formed by the first segment, and a third segment extending from the second segment in an arc having one or more radii of curvature greater than the radius of the optic which terminates in a free end spaced outwardly from the optic periphery.
