Abstract: A preloaded intraocular lens injection device includes a retainer for releasably holding an IOL in an unstressed state. The retainer and IOL are removably attached to an injector body and are sealed in the same package for delivery to a surgeon. In an alternate embodiment, the retainer and IOL are coupled together and sealed in one package and the injector body is sealed in a separate package with the surgeon attaching the retainer to the injector body at the time of surgery. To deliver the IOL through the injector body, the retainer is removed from the injector body causing the IOL to release from the retainer and become located in an unstressed state in the injector body. A compressor is moved to the closed position to compress the IOL, the injector tip is inserted through a small incision in an eye and a plunger is advanced to push the IOL through and out the injector body tip and into an eye.

Abstract: A method of folding a multiple element IOL comprising folding the first lens element and second lens element such that the second lens element at least partially surrounds the first lens element and such that, after folding, both the first lens element and the second lens element are substantially aligned along the optical axis. A hinged apparatus such as a cartridge may be used to cause the second lens element to be folded. A method of loading a multielement IOL comprising folding the haptics such that a portion of the haptics contacts an exterior side of one of the first lens element and the second lens element.

Abstract: A device for injecting an intraocular lens (IOL) into an eye, the device having an injector body including a lumen and an open tip wherethrough the IOL is expressed from the device. An IOL loading bay is located in the passageway wherein the IOL is positioned and compressed. The injector tip is dimensioned to allow the surgeon to choose an insertion depth between first, second and third transition points defined on the tip, the first and second transition points having a larger diameter than the third transition point which is located closer to the open tend of the tip. If the surgeon wishes to insert through a very small incision size (e.g., about 2.4 mm), the surgeon will insert the tip only up to the third transition point. The injector is stable during delivery of the IOL therethrough due to a spreading of the tip within the eye which effectively anchors the tip during IOL delivery.

Abstract: A mold assembly for the manufacture of at least one ophthalmic device used in or on the eye is disclosed. The mold assembly includes a mateable pair of mold parts wherein at least one of the mold parts comprises at least an oxygen-absorbing mold material and an oxygen scavenger composition containing (i) an oxygen scavenging polymer comprising a polymer backbone and one or more substituted or unsubstituted cyclic olefinic groups covalently linked to the polymer backbone; and (ii) an oxygen scavenging catalytic amount of a transition metal catalyst.

Abstract: A device for injecting an intraocular lens (IOL) into an eye, the device having an injector body including a lumen and an open tip wherethrough the IOL is expressed from the device. An IOL loading bay is located in the passageway wherein the IOL is positioned and compressed. In a first aspect of the invention, the passageway diameter increases from a point adjacent the loading bay to the open tip to reduce compressive force on the IOL as it travels through the lumen. In another aspect of the invention, the plunger tip has a shape and diameter which has a close, sliding fit with the shape and diameter of the passageway to reduce the chance of the IOL becoming wedged between the plunger tip and the passageway wall as the plunger tip engages and advances the IOL through the passageway.
