First patented disposable calibration system for PRK.ORLANDO, Fla.--(BUSINESS WIRE)--Nov. 9, 1995--LaserSight Incorporated (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :LASE) announced today that on October 24, 1995 U.S. Patent No. 5,460,623 was issued. This patent covers the use of the first patented, disposable, calibration system (Ex-Calibur(TM)) for excimer laser A gas laser in which a very short electrical pulse excites a mixture containing a halogen such as fluorine and a rare gas such as argon or krypton. It produces a brief, intense pulse of ultraviolet light. photorefractive keratectomy Photorefractive keratectomy (PRK) A procedure that uses an excimer laser to make modifications to the cornea and permanently correct myopia. Mentioned in: Myopia, Radial Keratotomy photorefractive keratectomy (PRK PRK photorefractive keratectomy. Photorefractive keratectomy (PRK) A procedure that uses an excimer laser to make modifications to the cornea and permanently correct myopia. ). This system provides a quantitative simulation of the proposed laser treatment pattern before each eye is treated. It is the only system that gives the surgeon detailed information on the proposed ablation size, shape, homogeneity, depth, and centration. Thus, it tests the laser hardware and software performance as an integrated system. "The VISX laser has used a lensmeter to infer the amount of correction and the Summit laser has used nothing but a power meter," according to Craig Beyer, D.O., Medical Director of LaserSight. "Because there is no way to monitor the ablation accuracy during the PRK treatment on an eye, quantitative pre-treatment calibration is essential." LaserSight is in advanced negotiations to market worldwide its calibration system with its disposable target substrate in conjunction with a leading manufacturer of corneal topography. It proposes to charge $25-$50 per test. "We are very excited about the economic potential of our calibration system for the Company, because it represents the opportunity to develop a recurring revenue stream from the use of any excimer laser," said Mike Farris, President and Chief Executive Officer of LaserSight. "If the unprecedented per-surgical procedure royalty fee of the Pillar Point Partnership is successfully challenged by the FTC FTC See Federal Trade Commission (FTC). , then our patented, single-use calibration system represents about the only avenue to participation in laser utilization regardless of laser ownership." The Ex-Calibur(TM) patent is a compliment to the Company's existing portfolio which includes patents for the treatment of Glaucoma and Macular Degeneration macular degeneration, eye disorder causing loss of central vision. The affected area, the macula, lies at the back of the retina and is the part that produces the sharpest vision. , as well as the patent for LaserSight's solid state LaserHarmonic, the world's first totally solid state laser for PRK.
