Carbon dioxide laser microsurgical vasovasostomy
Urology, 1985Microsurgical carbon dioxide (CO2) laser vasovasostomy was successfully achieved by fusion coagulation of protein under similar laboratory conditions as those seen in the operating room. Speed of performance, patent lumen, and lack of granuloma formation support the CO2 laser's ability to simplify this technique.

Intraocular Carbon Dioxide Laser Photocautery
Ophthalmology, 1980The indications and contraindications for the use of carbon dioxide laser photocautery at the time of vitrectomy have been reviewed. Indications include posterior retinal tears either in flat or elevated sensory retina; elevated fibrovascular fronds on the optic nerve or elsewhere; flat neovascularization elsewhere, bleeding rubeotic iris vessels.

Carbon dioxide laser circumcisions for children
Pediatric Surgery International, 2003The carbon dioxide laser for circumcision was introduced by our department in 1989. This study aims to review our experience with laser circumcision for children and to evaluate its cost effectiveness as compared to conventional methods. A retrospective study of 30 patients who underwent conventional circumcision in 1985 and another 30 patients who ...

Carbon Dioxide Laser Surgery in Hemophilia
American Journal of Ophthalmology, 1983We used a carbon dioxide laser to remove a subcutaneous lipoma from the brow of a patient with classical hemophilia A. This technique made the cosmetic procedure safe and effective in a patient for whom surgery would otherwise have held a greater risk.

Tubal microsurgery with the carbon dioxide laser
American Journal of Obstetrics and Gynecology, 1983Thirty New Zealand White female rabbits underwent tubal resection and reanastomosis for comparison of conventional microsurgery and laser microsurgical techniques. The rabbits were divided into three groups. The first group of 10 rabbits had 3 cm of tissue resected by knife from each uterine horn; the cut ends were then reanastomosed in one layer with ...

Stapedectomy Training With the Carbon Dioxide Laser
The Laryngoscope, 1997AbstractAll primary carbon dioxide (CO2) laser stapedectomies supervised by the senior author since 1986 were retrospectively reviewed and reported according to 1995 American Academy of Otolaryngology‐Head and Neck Surgery Committee on Hearing guidelines. Sixty‐three cases had more than 6 weeks of follow‐up with an average residual gap of 6.49 dB (SD =

Carbon Dioxide Laser Hazards to the Eye
Nature, 1967LASER radiation in the infra-red, for example from a carbon dioxide laser, is heavily absorbed in the surface layer of any biological tissue. The laser beam interacts strongly with tissue to produce heat, and thermal lesions can easily occur in the bare skin on the hands and the face.

1998
The efficient use of high power lasers for material processing depends on several properties of the laser beam. First of all the intensity must reach at least a million Watts per cm2 to achieve secure melting and evaporation of the workpiece, which are both necessary for nearly all production processes with lasers such as cutting, ablation, welding and

Intraocular carbon dioxide laser photosurgery
Lasers in Surgery and Medicine, 1980AbstractIntraocular carbon dioxide laser has been used for photocautery and photo‐incision as an adjunct to vitrectomy. This utilizes a new fluid‐tissue interface application for the 10.6 micrometer wavelength infrared radiation. The use of an intraocular probe with an infrared transmitting window through a pars plana incision allows the placement of ...

Carbon Dioxide Laser Laparoscopy for Endometriosis
Obstetrics and Gynecology Clinics of North America, 1991In conclusion, the CO2 laser has been useful for the vaporization and excision of endometriosis through the laparoscope. Removal through the laparoscope, however, requires recognition of the lesion. Microscopic lesions may not be seen through the laparoscope, and deep invasive lesions may be more palpable than visual.
