What Is Laser Surgery? - Stanford Health Care- laser definition medical ,Laser surgery is a type of surgery that uses special light beams instead of instruments, such as scapels, to perform surgical procedures. There are several different types of lasers, each with characteristics that perform specific functions during surgery. Laser light can be delivered either continuously or intermittently and can be used with ... Laser Definition & Meaning - Merriam-WebsterMedical Definition of laser (Entry 1 of 2) : a device that utilizes the natural oscillations of atoms or molecules between energy levels for generating coherent electromagnetic radiation usually in the ultraviolet, visible, or infrared regions of the spectrum laser transitive verb Medical Definition of laser (Entry 2 of 2)
A YAG laser capsulotomy is an outpatient procedure. The patient may wait in the outpatient surgery area or the doctor' office for 1 to 2 hours after the treatment. This is to have the pressure in the eye (intraocular pressure) checked. Patients should not feel any pain after the surgery. Patients are usually prescribed topical steroids or non ...
Laser surgery is a type of surgery that uses special light beams instead of instruments for surgical procedures. LASER stands for "Light Amplification by the Stimulated Emission of Radiation." Lasers were first developed in 1960. Newer laser modifications continue to have a large impact on medical and surgical practices.
a device that transfers light of various frequencies into an extremely intense, small, and nearly nondivergent beam of monochromatic radiation in the visible or invisible spectrum, with all the waves in phase; capable of mobilizing immense heat and power when focused at close range, lasers act on tissues by photocoagulation and photodisruption …
Laser therapy may be used to: shrink or destroy tumors, polyps, or precancerous growths. relieve symptoms of cancer. remove kidney stones. remove part of the prostate. repair a detached retina ...
Medical Lasers Definition. A laser is a device that transforms one type of energy, usually electrical, into optical energy. The light waves in the beam produced by a laser are nearly parallel (collimated), nearly monochromatic, and coherent. The light beam is produced by exciting atoms and causing them to radiate their energy in phase.
A “laser,” or individual-specific deductible, in the context of stop-loss insurance refers to a type of exclusion or limitation placed on a specific plan member’s individual stop-loss threshold. So even though you may have purchased stop-loss coverage to protect your medical plan from excessively high claims, stop-loss underwriters have ...

Laser-assisted in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision. In eyes with normal vision, the cornea bends (refracts) light precisely ...
LASER is an acronym which stands for Light Amplification by Stimulated Emission of Radiation. The laser produces an intense, highly directional beam of light. The most common cause of laser-induced tissue damage is thermal in nature, where the tissue proteins are denatured due to the temperature rise following absorption of laser energy. The ...
1. (noun) Device that concentrates high energies into an intense narrow beam of nondivergent monochromatic electromagnetic radiation; used in microsurgery, cauterization, and for a variety of diagnostic purposes. 2. (verb) To treat a structure with a laser beam. [acronym coined from light amplification by stimulated emission of radiation]
Typically, a laser is utilized when the stop loss market tightens up, therefore decreasing competition among insurance carriers. A self-insured plan can only absorb a couple of lasers. Lasers should not be employed to address all high health care costs a self-insured plan may have. Though not necessarily mandated, lasering remains a common ...
Laser ablation: A laser is used for superficial (surface) lesions or discoloration. Chemoablation: Topical acids are used to peel skin or remove warts. Cryoablation: Cold gases like liquid nitrogen or argon freeze the skin. 2. Fulguration: High-frequency electrical currents remove small lesions or warts. 3.

Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair. During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs.

Cold laser therapy is used to encourage skin rejuvenation. Dermatologists use it to treat various skin problems, including: acne and acne scars. psoriasis. burns. vitiligo. edema, or swelling of ...
Medical lasers are medical devices that use precisely focused light sources to treat or remove tissues. The term “laser” stands for Light Amplification by Stimulated Emission of Radiation. Ordinary...
Laser-based fiber optic wires are utilized in fiber optic networks because they are exceedingly light. Because lasers are less dangerous than X-rays, they are extensively employed in the medical field for cancer diagnostics. Disadvantages: Lasers are costly, thus patients who require laser-based treatment choices will have to spend a lot of money.
Types of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses. Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor. Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. The neodymium-YAG laser emits ...
Laser Definition. A laser is an optical amplifier - a device that strengthens light waves. Some lasers have a well-directed, very bright beam with a very specific color; other lasers emphasize different properties, such as extremely short pulses. The key feature is that the amplification makes light that is very well defined and reproducible ...
For visible-beam consumer lasers, there are four main classes. Each is described in more detail here: Class 2, Class 3R, Class 3B and Class 4. The first two Classes are relatively safe for eye exposure; the last two are hazardous. The chart below shows how the eye injury hazard increases as the laser’s power increases. The detailed ...
