Appl. No.:

10/232557

Inventors:

Phillip J. Erickson - Medina WA

Peter G. Harrington - Seattle WA
Raymond D. Graham - Renton WA

Assignee:

Ocular Instruments, Inc. - Bellevue WA

International Classification:

A61B 300

US Classification:

351219

Abstract:

An ophthalmoscopic prism, for example a gonioscope, has an optically transparent body, the distal end carries a viewing surface preferably oriented perpendicularly to the optical axis of the body, the proximal end of the prism carries a concave surface having a curvature similar to the curvature of the cornea of a patient. The proximal end has at least one planar surface extending outwardly and distally from a location adjacent the periphery of the concave surface. The body has an index of refraction that provides total internal reflection to a viewer looking through the viewing surface even when the planar surface is at least partially wetted with a fluid.

International Classification:

A61B 3/00
A61B 3/10

US Classification:

351219, 351221

Abstract:

A gonio lens is provided including a contact lens element and a geometric reference member. The contact lens element has an optical axis, a concave posterior contact surface to be placed in optical contact with the cornea of a patient's eye, and an anterior surface. The geometric reference member, such as a scale, is provided near the concave posterior contact surface of the contact lens element. The configuration and location of the geometric reference member are chosen to provide an image of the geometric reference member adjacent to an image of the periphery of the anterior chamber of the eye of a patient within a field of view of the contact lens element when the contact lens element is placed on the eye of a patient. The two images are formed relative to each other such that they are simultaneously in focus to permit visual comparison between the two.

Appl. No.:

10/281430

Inventors:

Giovanni Staurenghi - Milan, IT
Raymond Graham - Renton WA, US
Peter Harrington - Seattle WA, US

Assignee:

Ocular Instruments, Inc.

International Classification:

A61B003/00

US Classification:

351/219000

Abstract:

A lens system for use with a scanning laser ophthalmoscope to produce a wide field of view includes a first lens set and a second lens set. The first lens set provides an aerial image of the fundus of an eye along an aerial image plane anterior to the first lens set. A second lens focuses laser light from a scanning laser ophthalmoscope on the aerial image, which is then refocused by the first lens set on the fundus. The second lens set also receives and provides reflected light focused at the aerial image and redirects it to the entrance pupil of the ophthalmoscope in a substantially collimated form.

International Classification:

A61B003/00
A61B003/14

US Classification:

351219000

Abstract:

A stereoscopic imaging lens includes a first lens set and a second lens set. The lens receives collimated laser light from the scanning laser ophthalmoscope and, focuses on the fundus of the eye. By use of a prism set, two offset images are provided to the scanning laser ophthalmoscope. The system provides virtually simulatneous side-by-side but offset images that can be viewed with a stereoscopic viewing device, which provides apparent depth perception.

OCULAR INSTRUMENTS, INC. - Bellevue WA

International Classification:

A61B 3/10
B29C 65/42
B29C 65/54

US Classification:

351219, 156293

Abstract:

An ophthalmologic lens assembly includes a glass prism bonded to a meniscus lens at a posterior end of the glass prism. The glass prism is surrounded by a housing that is bonded to the meniscus lens. In one embodiment, the housing and a meniscus lens blank are processed by grinding and polishing the housing and meniscus lens blank together to form a posterior lens surface of a meniscus contact lens. In other embodiment, only the meniscus lens blank is processed by grinding and polishing to form a posterior lens surface of a meniscus contact lens.

Appl. No.:

5/841035

Inventors:

Raymond Graham - Mountain View CA

Assignee:

Dytek Corporation - Mountain View CA

International Classification:

A61B 1736
A61N 306

US Classification:

12830314

Abstract:

Electro-surgical pencils are used with a variety of commercially available machines which produce two different types of electrical impulses--one for cutting, the other for cauterizing. In the system of this invention there is a pencil having an electrode received therein (preferably the electrode being reversible to expose two different working ends) and having a finger-actuated, toggle-type switch in the pencil to selectively connect either of the types of electrical impulses to the electrode. A cord having at least three conductors extends from the switch to an adapter which is a multi-contact plug fitting into a matching socket in the machine or permanently attached to the machine. The end of the cord remote from the pencil is received in the adapter and electrical contact with the conductors is expeditiously established. Preferably, the pencil is used with a cup attached to a surgical drape for convenient deposit between uses.
