International Classification:

A61B 1818

US Classification:

606 5, 606 4, 606 10, 351212

Abstract:

An ophthalmic surgery system and method for treating presbyopia by performing ablative photodecomposition of the corneal surface. A laser system ablates tissue to a predetermined ablation shape, and the cornea heals significantly to form a multifocal shape correcting presbyopia. The multifocal shape corrects for near-vision centrally and far-vision peripherally. The system and method enables wide area treatment with a laser having a narrower beam than the treatment area, and can be used in the treatment of many conditions in conjunction with presbyopia such as hyperopia, hyperopic astigmatism and irregular refractive aberrations.

Abstract:

An ophthalmic surgery system and method for treating presbyopia by performing ablative photodecomposition of the corneal surface. The offset image of a variable aperture, such as a variable width slit and variable diameter iris diaphragm, is scanned in a preselected pattern to perform ablative sculpting of predetermined portions of a corneal surface. The scanning is performed to ablate an optical zone sized to match the patient pupil with a peripheral transition zone outside the pupil. The shape of the ablated optical zone is different from the shape of the final optical correction on the anterior surface of the cornea. The optical zone corrects for near-vision centrally and far-vision peripherally. A movable image displacement mechanism enables radial displacement and angular rotation of the profiled beam exiting from the variable aperture. The invention enables wide area treatment with a laser having a narrower beam than the treatment area, and can be used in the treatment of many conditions in conjunction with presbyopia such as hyperopia, hyperopic astigmatism and irregular refractive aberrations.

Inventors:

Kenneth Greenberg - Long Island City NY
Alberto Sid - Upper Saddle River NJ

Assignee:

MAF Technologies Corp. - Upper Saddle River NJ

International Classification:

G05F 100

US Classification:

315291

Abstract:

A multiple discharge tube lighting system has a plurality of gas discharge tubes positioned behind a translucent panel, within a cove or tube or in close proximity to each other and each tube is connected through a power supply to a dimming control circuit. The control circuit is used to change the brightness and on/off state of each tube to create the appearance of different colors when the tubes are viewed in combination using dimming and/or interleaving. The control circuit can match dimming curves, and stores, retrieves and sends power information for each tube to create displays which can be identically produced repeatedly.
