Clinical Results of Laserscope Laser Treatments to be Presented at ASLMS Annual Meeting

Clinical Representation in Aesthetics, Urology and Otolaryngology

SAN JOSE, Calif., April 5 (HSMN NewsFeed) -- Laserscope (Nasdaq: LSCP ), a pioneer in the development and commercialization of minimally-invasive medical devices, including medical lasers and advanced fiber-optic delivery devices, will feature prominently its two leading laser technology platforms, the Gemini® and GreenLight PV® laser systems in a variety of research studies and presentations at the American Society for Laser Medicine and Surgery (ASLMS) 26th Annual Meeting, April 5 - 9, 2006 in Boston, MA.

"We are pleased to be the only company at the ASLMS Annual Meeting to have clinical experts present data on our applications in three disciplines: aesthetics, urology and otolaryngology. The presentation of these important findings in this forum is an excellent opportunity to further educate the marketplace about Laserscope's superior technology, broad product applications and numerous patient benefits," said Eric Reuter, President and Chief Executive Officer of Laserscope. "In addition to updates on the current urology and aesthetic product line-up and applications, we are also pleased to see physicians from other specialties finding potentially new applications for high power 532 nm wavelength laser energy. We are looking forward to investigating the potential market size, economics, and technological differentiation that new applications may bring to the Company."


Two of the studies presented will report on successful clinical results obtained by urologists using the GreenLight PV laser system to treat benign prostatic hyperplasia, or non-cancerous, enlarged prostate, that affects over 2.5 million men in the United States and several times this number internationally. In addition, another study will examine the underlying technology of the GreenLight PV laser system's treatment effects by observing changes in animal soft tissues exposed to 532 nm laser energy.

The PVP procedure using the GreenLight PV laser system is a minimally- invasive alternative to the Trans-Urethral Resection of the Prostate (TURP) surgical procedure to treat benign prostatic hyperplasia. Over 120,000 PVP procedures have been performed worldwide and long-term clinical data has demonstrated that the PVP procedure offers the same clinical outcomes as TURP without the side effects and at a reduced cost.

Investigators who will report their findings relating to the GreenLight PV laser system include Po N. Lam, MD, and colleagues from the University of Oklahoma ("High Power KTP Laser Photo-Selective Vaporization Prostatectomy for Large Volume Benign Prostactic Hyperplasia" and "High Power KTP Laser Photo-Selective Vaporization Prostatectomy and Refractory Urinary Retention Secondary to benign prostatic hyperplasia").

Urologists with extensive clinical experience using the GreenLight PV laser system will also contribute other presentations at the ASLMS Annual Meeting. Nathaniel M. Fried, MD, of the Johns Hopkins Medical Institutions, Baltimore, MD, will give a Laser Innovation Lecture on "The Future of Lasers in Urology." Alexis E. Te, MD, of the Cornell University Weill Medical College, New York, NY, will present a "State of the Art Lecture on Photo-Selective Vaporization of the Prostate," and will also speak on the GreenLight PV laser system in a Point-Counterpoint Session. Ricardo R. Gonzalez, MD, and colleagues, also from the Weill Medical College, will discuss "High-Power KTP Laser Photo-Selective Vaporization Prostatectomy: The Cornell Experience."


In the aesthetic medicine section of the ASLMS, several studies will be presented examining the Gemini's use of the 532 nm wavelength for treatment of facial telangiectasia and rosacea, an acne-like skin condition affecting about 13 million people in the United States. These studies reflect increasing clinical interest in the Gemini 532 nm wavelength laser technology. The Gemini, 532 nm wavelength, delivers the high-power, green laser energy that clears redness faster and more effectively than traditional pulsed dye lasers. The Gemini system's 10 mm laser spot size is the largest available, enabling physicians to safely and effectively provide rapid treatments of large surface areas. The spot size is also continuously adjustable from 1 mm to 5 mm so that tiny blood vessels can be eliminated more precisely than with less targeted intense pulsed light systems.

Dermatologists at the ASLMS professional program will report new research on the treatment of rosacea-associated erythema using the 532 nm wavelength with the Gemini system. These findings will be presented by Arielle Kauvar, MD, from the New York Laser and Skin Care Center.

The effects of Gemini's 532 nm wavelength versus the 595 nm wavelength generated by the pulsed dye laser in the treatment of facial telangiectasia and redness will also be discussed. This study was conducted by Nathan Uebelhoer, MD, and Jeff Dover, MD, at Skin Care Physicians of Chestnut Hill, NJ.


In otolaryngology, L.M. Akst, MD, from Massachusetts General Hospital, Wellman Laboratories of Photomedicine, Harvard Medical School, Boston, MA will present "Soft-Tissue Effects of Pulsed-KTP Laser on Excised Calf Vocal Folds." This innovative research supports the recent introduction of pulsed KTP laser technology into the realm of vocal cord surgery.


The American Society for Laser Medicine and Surgery (ASLMS) was founded in 1980 and is the world's largest professional organization dedicated to promoting excellence in patient care by advancing laser applications and related technologies. The Society's membership includes physicians and surgeons representing more than 45 medical specialties, nurses and other allied health care professionals, physicists involved with product development, biomedical engineers, biologists and equipment manufacturers. The Society currently has over 3,000 members, including approximately 550 members who are not in the United States.

The ASLMS 26th Annual Meeting will be held in the Sheraton Boston Hotel and Hynes Convention Center. Laserscope will display the Gemini laser system in Technical Exhibit #401.
