Holmium Laser Canaliculoplasty
Ophthalmic Plastic & Reconstructive Surgery, 1996Thirty canaliculi of 18 patients with complete or nearly complete canalicular obstruction were subjected to laser canaliculoplasty as a substitute for the standard Jones-type bypass conduct. Etiologies for the obstruction included congenital lacrimal system atresia, eyelid trauma, scarring following previous lacrimal surgery, and chronic inflammatory ...

Holmium laser prostatectomy: current techniques
Urology, 2002During the past 7 years, holmium laser prostatectomy has evolved into an enucleation procedure, incorporating the use of established surgical planes. Holmium laser enucleation of the prostate (HoLEP) uses the excellent incisional and hemostatic properties of the holmium laser wavelength.

Current Opinion in Urology, 1998
This review documents the evolution of the current techniques of Holmium:yttrium-aluminium-garnet (Ho:YAG) laser prostatectomy. An increasing number of centres are accumulating experience with this wavelength in the surgical treatment of Benign Prostatic Hyperplasia.

Transmyocardial Revascularization with Holmium Laser
Cardiology, 1998Sixteen patients with angina refractory to medical therapy who were not considered suitable for standard revascularization underwent transmyocardial revascularization with holmium laser. The average age of the patients was 63.2 ± 10.5 years. All of them had angina class 3 or 4, and 9 (56%) had previously undergone an aortocoronary bypass grafting. Four

Journal of Clinical Laser Medicine & Surgery, 1998
To review the physics related to the holmium laser, its laser-tissue interactions, and its application to the treatment of urological diseases.The holmium: YAG laser is a solid-state, pulsed laser that emits light at 2100 nm. It combines the qualities of the carbon dioxide and neodymium:YAG lasers providing both tissue cutting and coagulation in a ...

Intrarenal use of the holmium laser
Lasers in Surgery and Medicine, 1997We investigated the safety, effectiveness, and techniques of the holmium (Ho:YAG) laser intrarenally. Data are presented on 52 patients who were treated with the Ho:YAG laser intrarenally for urinary calculi or neoplasms.The Ho:YAG laser has a wavelength of 2,100 nm, which is delivered in pulsed fashion via a small flexible quartz fiber (365 microns ...

AIP Conference Proceedings, 2007
The addition of a variable pulse duration to lasers used for stone removal adds another factor which can modify the effect of the holmium laser on stone fragmentation. More complex combinations of variables with the other adjustable features of the laser may provide more effective stone fragmentation clinically.

ILSC '92: Proceedings of the International Laser Safety Conference, 1992
The Holmium laser produces an invisible 2100nm infrared that is transmitted via a 400 micron fiber and rigid handpiece. This technology has been used on over 400 orthopedic surgeries in the last two years at St. Peter Hospital. Safety policies and procedures based on ANSI Z136.3, OSHA, and AORN guidelines have been developed for use of the Holmium ...

Holmium: Yag Laser Angioplasty
Acta Radiologica, 1992This experimental study was designed to define the potential value of a mid-infrared holmium laser in the free running mode for angioplasty. Immediately after removal, fresh normal and diseased human cadaveric arteries were irradiated under saline with a Ho:YAG laser (wavelength 2.13 μm). The laser was pulsed at 3 Hz, 250 μs pulse width and fluences of

Holmium laser?induced coronary thrombolysis
Journal of Thrombosis and Thrombolysis, 1996Plaque disruption and thrombosis are determinants for the onset of acute ischemic syndromes. The presence of intracoronary thrombus is associated with an increased risk of complications during revascularization with balloon angioplasty. Thrombi avidly absorb light in the mid-infrared optical spectrum due to their high water content.
