摘要： Ophthalmic lens assemblies and methods of assembly and use may include a lens assembly including a lens element and a protective cover. The lens element includes a contact lens surface and a faceted optical body including a distal portion and a faceted portion including one or more mirror facets to form a TIR activity pathway. The protective cover includes a contact aperture shaped to receive the contact lens surface, a grip portion, and a facet housing portion including an interior surface. The contact aperture of the protective cover is stretch-fit about a periphery of the contact lens surface to maintain a proximal-side fluid seal. The grip portion of the protective cover is stretch-fit about the distal portion of the lens element to maintain a distal-side fluid seal. One or more TIR-inducing air gaps are defined by the facet housing portion between the interior surface and the mirror facets.

摘要： A lens arrangement for use in vitreous retinal surgery includes a contact lens element (18) including a posterior surface (12) having a shape adapted to fit an average cornea for placement on a patient's eye, and an anterior surface (24). The contact lens element transmits light emanating from the patient's eye for viewing a structure of the patient's eye. A flange (30) surrounds, holds a peripheral region of the contact lens element, and extends radially onto the scleral region of the patient's eye. The flange has a posterior surface with a shape adapted to fit an average scleral curvature so that the flange rests on the sclera for stabilizing a position of the contact lens on the patient's cornea. The flange includes at least one opening (50) allowing access to an incision through which a surgical tool or instrument may be inserted into the eye.

摘要： The invention is directed to an ophthalmoscopic or gonioscopic lens system (10) as well as an adapter lens system for use with such an associated lens apparatus. The indirect ophthalmoscopy lens of the invention for use in examination or laser treatment of a patient's eye (16) comprises a hand-held, pre-set or fixed system having at least two lens elements each having first and second surfaces. At least one of the lens elements includes an aspheric surface of revolution. The at least two lens elements are positioned adjacent one another in a housing, such that the refractive properties of each are combined to converge light from an illumination light source to the entrance pupil (18) of the patient's eye to illuminate the fundus (20) thereof and form a fundus image to be viewed. The adapter lens systems of this invention are designed for use with an associated ophthalmoscopic lens, enabling selective modification of the optical characteristics of the ophthalmoscopic lens system in a predetermined manner. Within the scope of this invention, a plurality of attachments make possible change in the net power, optical imaging characteristics, magnification, laser transmission properties or other characteristics of a particular ophthalmoscopic lens.

摘要： A gonioscopic viewing system is provided for diagnosis or laser treatment of the anterior chamber angle of a patient's eye. A first lens system (10) includes a concave posterior lens surface (2) with a shape substantially corresponding to the shaped of an average cornea (C) so that, when placed on a patient's eye, light rays originating at the anterior chamber angle and passing through the aqueous humor, pass through the cornea and the posterior lens surface of the first lens system and are directed by the first lens system toward an image forming system. An image forming system is optically aligned with the first lens system for capturing the light rays directed by the first lens system and focusses the light rays to form a real image of the anterior chamber angle outside of the patient's eye.

摘要： A lens for use in indirect ophthalmoscopy having two functions; firstly as a condensing lens converging light from an ophthalmoscope light source to the pupil of the eye and thereby illuminating the fundus of the eyes, and secondly and simultaneously as an image forming lens which forms an aerial image of the fundus of the eye, which image is viewed monocularly with a monocular indirect ophthalmosope or binocularly and stereoscopically with a binocular indirect ophthalmoscope. Both the front and back surfaces of the lens are positive aspheric surfaces of revolution of conoid type on a common axis of revolution, the dioptric power at the apex of the front surface of the lens ranging between 1.5 to 2 times the dioptric power at the apex of back surface of the lens, the eccentricities of the two surfaces of the lens being a function of the sum of the dioptric powers of the two surfaces of the lens, the eccentricities and apical dioptric powers of the surfaces of the lens being such that the lens converges the light from the ophthalmoscope light source to a precise image of the source at the entrance pupil of the eye, and simultaneously the lens forms with the light emerging from the eye a substantially flat aerial image of the fundus of the eye in which image the aberrations of the image including curvature, astigmatism and distortion are optimally corrected.

摘要： A head-borne binocular indirect ophthalmoscope for viewing the aerial image of the fundus of the eye (I), having the unique feature that it incorporates within each of its two observing portions a two-lens telescope (u) of low magnifying power which magnifies said aerial image (i) of the fundus (F). The telescope differs from the usual coaxial type in that the optical axis of the high powered objective lens and that of the high powered ocular lens of said telescope are caused to intersect each other at an angle of about 94o at the surface of a laterally positioned oblique front surface mirror (b), said lenses and mirror being in a fixed relationship to each other within a transversely movable mounting as a fixed telescope unit such that the reflected secondary focus of the objective lens falls at the primary focus of the ocular lens.
