Abstract: The invention contemplates a combined contact lens and haptic wherein the outer edge of the haptic has peripherally continuous integrity and wherein the haptic is so axially compliant that it is self-adapting to the curvature of the cornea to which it is applied. The construction is such as to be self-cleansing in conjunction with natural moisture on the surface of the cornea, and to be inherently non-promoting of enzyme development on the cornea.

Abstract: The invention contemplates effectively integral lens-and-haptic structure and a technique of making the same, using composite laminated sheet material as the only ingredient of the ultimate product, which may be an intraocular implant or for extraocular (i.e., cornea-contact) application. The composite sheet material is of substantially the combined ultimate thickness of the lens and haptic, one of the laminations being of a material destined to be substantially only the lens component, and another of the laminations being of a material destined to be substantially only the haptic component. The lens-component lamination may be of optical-quality glass or of a transparent plastic which is inert to body fluids. Suitably coordinated masking and etching steps determine the contour of the ultimate central circular lens as well as the thickness and fenestration detail of the ultimate thin flexible haptic formations which are integral with and extend radially outward of the lens blank.

Abstract: The invention contemplates haptic construction for support of a finished intraocular lens element, wherein the haptic has plural radially outward stabilizing-leg formations, which incorporate a feature of radial adaptability in terms of the anterior-chamber wall size to which the lens may be fitted. Various embodiments are described to illustrate application to a single-piece and to multiple-piece haptics, and to illustrate radially compliant yieldability as well as ratchet-retention of a selected radial span of the stabilizing leg formations.

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. The lens of the invention is particularly adapted for posterior-chamber implantation, with position stability derived from the inner wall of the natural-lens sac (from which cataracted material has been removed). A manipulative tool in combination with the lens assembly (1) provides safe stabilizing support during storage and transit prior to the surgeon's access for operative use, and (2) is configurated to facilitate operative placement of compliant retaining feet within the sac, permitting posterior-chamber positioning of the lens prior to tool removal.

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.
