6394605, May 28, 2002

Filed:

May 23, 2001

Appl. No.:

09/863561

Inventors:

John A. Campin - Orlando FL
Gary P. Gray - Orlando FL
George H. Pettit - Maitland FL

Assignee:

Alcon Universal Ltd. - Hunenberg

International Classification:

A61B 300

US Classification:

351246

Abstract:

An automated focusing method for a wavefront sensor that iteratively determines the best optics setting for the wavefront sensor by making objective measurements of the patients focus without the need for subjective information from the patient.

International Classification:

A61B 9018

US Classification:

606 10, 606 5

Abstract:

A surface treatment laser beam delivery and tracking system is provided. The laser generates laser light along a original beam path at an energy level suitable for treating (e. g. , eroding) a surface. An optical translator shifts the original beam path onto a resulting beam path. An optical angle adjuster changes the angle of the resulting beam path relative to the original beam path such that the laser light is incident on, and spatially distributed, the surface to be treated. A motion sensor transmits light energy to the surface and receives reflected light energy from the surface via the optical angle adjuster. The light energy transmitted by the motion sensor travels on a path that is parallel to the shifted beam as they travel through the optical angle adjuster. The reflected light energy is used by the motion sensor to detect movement of the surface relative to the original beam path and generate error control signals indicative of the movement. The optical angle adjuster is responsive to the error control signals to change the angle of the resulting beam path and the angle of the motion sensors light energy in correspondence with one another.

International Classification:

A61B 1018

US Classification:

606 12, 606 5, 606 10, 606 13, 351209

Abstract:

An ophthalmic laser system includes a laser beam delivery system and an eye tracker responsive to movement of the eye operable with a laser beam delivery system for ablating corneal material of the eye through placement of laser beam shot on a selected area of the cornea of the eye. The shots are fired in a sequence and pattern such that no laser shots are fired at consecutive locations and no consecutive shots overlap. The pattern is moved in response to the movement of the eye.

Assignee:

Alcon Universal Ltd. - Hunenberg

International Classification:

A61N 501

US Classification:

606 5, 606 10, 607 89

Abstract:

A system for protecting a sector of tissue from exposure to surgically directed radiation includes a processor and an input device, a camera, and an output screen in electronic communication with the processor. A software resident on the processor receives camera data containing an image of a region of tissue, which includes at least a portion of a predetermined area desired to receive therapeutic radiation. The software also routes the image for display superimposes thereon first indicia indicative of the predetermined area. Data are received on a location of a sector of the tissue desired to be protected from the radiation and for superimposing on the displayed image second indicia indicative of the sector. In a specific embodiment the tissue is an eye and the predetermined area is at least a portion of the cornea.
