US Patent:

46659145, May 19, 1987

Filed:

Dec 27, 1985

Appl. No.:

6/814223

Inventors:

Emanuel Tanne - Vancouver WA

International Classification:

A61F 1732

US Classification:

128305

Abstract:

An instrument for automating corneal surgical procedures, such as radial keratotomy and other corneal operations, which includes one or more probe sensors with extendible tips which, by measuring electrical resistivity, are responsive to contact occurring with the corneal surface. Positioning of the probe sensor(s) over various points of the corneal surface provides data signals which enable the surface topography of the cornea to be mapped by a micro-processor. A surgical knife having automatic depth control is provided whose operation is regulated in response to changes in the electrical resistivity between the knife and the human body as penetration is made into the layers of the cornea. The probe sensor(s) and knife are used with a ring-like fixture attachable by vacuum to the eye and comprised of a fixed outer ring and a movable inner ring, the fixture providing mounting and/or support for these elements while permitting their movement to different meridial locations by rotation of the inner ring. One arch element bridging a diameter of the ring fixture supports the probe sensor(s) and a second arch element has guideways thereon for controlling the movement and positioning of the knife.

Abstract:

An eye transport apparatus adapted for placement within a carrying chamber is provided. The apparatus is preferably made of plastic, and includes a base having a concave upper surface sized to receive an eye globe. The center of the concave surface also includes an opening for the optic nerve. Positioned in the sides of the base are a plurality of holes and channels. The holes are designed to receive pins used to secure the optic nerve in position. The channels are designed to allow antimicrobial materials in the chamber to pass freely along the sides of the base. Finally, the apparatus includes at least one elongate stabilizing arm extending outwardly from the base. All of these features combine to provide an eye transport device which is both effective and easy to use.
