Abstract: The invention contemplates an improved lens implant for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed via the pupil at the iris as the operative step following removal of cataract material. The invention features flexible haptic structure assembled to and retaining an optically finished lens element. The haptic structure integrally includes two asymmetrically defined generally diametrically opposed stabilizing feet which extend radially outward of the region of lens retention and which are each characterized by an arcuate peripheral band adapted for positioning engagement with structural features within one of the chambers of a human eye. Loop formations local to a single peripheral band and to the region of lens retention define localized openings adapted for reception of suture, pincer or other manipulative instrumentalities.

Abstract: The invention contemplates an intraocular lens or the like which so combines an optically finished lens element with supporting mount or haptic structure that a given astigmatic correction incorporated in the finish of the lens is automatically implantable with correct optical orientation of the correction axis. The mount is characterized with an angularly unique recognizable haptic formation from which a unique ultimately implanted orientation can be recognized by the ophthalmological surgeon, and the prescription orientation of the astigmatic correction is, upon lens-to-haptic assembly, set in such predetermined angular relation to the angularly unique haptic formation that correct optical orientation of the implant is assured.

Abstract: The invention contemplates improved intraocular-lens structures for use as implants in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed in the pupil at the iris as the operative step following removal of the cataracted lens. The lens features adapter structure assembled to an optically finished lens element and including one or more stabilizing feet which are formed integrally with the body of the adapter and which are axially offset from the adapter body to permit the stabilizing feet and the adapter body to engage opposite sides of the iris.

Abstract: The invention contemplates an autoclavable mounting and package for an intraocular lens of the variety which is an assembly of a lens element and one or more lens-retaining haptic elements. The mounting in a preferred form comprises a single stiffly compliant sheet which is folded at one end, so that an upper panel can be detachably secured in register with a lower panel, there being coacting formations of the registering panels whereby the lens can be supported by and between the panels and via the haptic structure of the lens assembly.

Abstract: The invention contemplates improved intraocular-lens structures for use as implants in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed through the pupil at the iris as the operative step following removal of the cataracted lens. The lens features adapter structure assembled to an optically finished lens element and including plural angularly spaced stabilizing feet which are formed integrally with the body of the adapter and which are axially offset from the adapter body to permit the stabilizing feet and the adapter body to engage features of the eye within the posterior chamber.

Abstract: The invention contemplates improved structure for use in making lens implants in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed in the pupil at the iris as the operative step following removal of the cataracted lens. The invention features adapter-element structure assembled or adapted for assembly to an intra-ocular lens element and having plural radially outward iris-stabilizable feet. The adapter-element structure is severably united to further material which aids in handling and storage, in readiness for later surgical use.

Abstract: The invention contemplates improved techniques for making lens implants for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed in the pupil at the iris as the operative step following removal of the cataracted lens. The lens produced by the inventive method features adapter structure assembled to an intra-ocular lens element and having first and second pluralities of radially outward stabilizing feet, the feet of one plurality being in angularly spaced and interlaced relation with the feet of the other plurality; and the respective pluralities of stabilizing feet are on opposite sides of the iris, enabling the iris to retain and position the implanted lens. At least two diametrically opposed feet are resiliently compliant and have openings for removable engagement with a manipulative tool.

Abstract: An improved lens implant for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed in the pupil at the iris as the operative step following removal of the cataracted lens. The invention features unitary adapter structure assembled to an intra-ocular lens element and having integrally formed first and second pluralities of radially outward stabilizing feet, in angularly spaced and interlaced relation, with the feet of the other plurality; and the respective pluralities of stabilizing feet are installed on opposite sides of the iris, thus enabling the iris to retain and position the implanted lens.
