Laser surgery is a type of surgery that cuts tissue using a laser in contrast to using a scalpel. [ 1 ] Soft-tissue laser surgery is used in a variety of applications in humans ( general surgery , neurosurgery , ENT , dentistry , orthodontics , [ 2 ] and oral and maxillofacial surgery ) as well as veterinary [ 3 ] surgical fields.
A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery. The word laser stands for "light amplification by stimulated emission of radiation". [2]
By the 1970s, he was applying low level laser light to treat people with skin ulcers. [12] In 1974, he founded the Laser Research Center at the Semmelweis Medical University in Budapest, and continued working there for the remainder of his life. [38] His sons carried on his work and brought it to the United States. [37]
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Approximately half of infections occur within 2 weeks of surgery, but delayed infection do occur up to a year after surgery. [15] Staphylococcus aureus was the most commonly identified bacteria for rapid onset and Pseudomonas aeruginosa was the most common identified bacteria for delayed onset.
Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...
ReLEx Small incision lenticule extraction (SMILE), second generation of ReLEx Femtosecond lenticule extraction (FLEx), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism.
Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 −12 s) or femtoseconds (10 −15 s). A laser operated in this way is sometimes referred to as a femtosecond laser, for example, in modern refractive surgery.
