What is a Laser?

Light amplification by stimulated emission of radiation is one of the most widely used technologies in medical science. Using this technology is cost-effective, without pain and complications. A laser is a high-energy excited light. Light amplification by stimulated emission of radiation is different from normal light. Laser can be created by special equipment. In this article, we introduce a number of laser applications in medicine .

The Use Of Lasers In Medicine

A laser is also a light. Laser has differences with ordinary light, which makes the laser’s efficiency extraordinary. The differences between laser and normal light are:

Ordinary light consists of visible and invisible light energy. Normal light consists of ultraviolet rays with the shortest wavelengths to infrared rays with the longest wavelengths. Laser consists of a type of light energy with a specific wavelength.


A laser is a monochromatic light. The accuracy and energy of laser is several thousand times higher than normal light.

The emission property of laser light is lower than normal light. When the laser is used in special devices, the laser passes its direct path exactly at a distance of several hundred meters. The radius of the radiation circle near the laser is equal to the radiation radius at several hundred meters of the laser. Because of this special feature, lasers are used in medicine.


 Laser applications in medicine

Use of laser in surgery

Due to the unique features of laser, laser is used in the field of medicine to treat diseases and surgeries.

Today, lasers are used instead of knives in surgeries. The advantages of using laser in surgeries are:

Wound cutting : The advantage of laser surgery compared to traditional surgery without laser is cutting the wound by laser rays. In traditional surgery without laser, after cutting with a knife, the patient suffers pain, bleeding, and problems with dressing and post-operative care.

Anesthesia : General anesthesia is one of the concerns and limitations of surgery. In laser surgery, the problem is solved with local anesthesia of the patient.

Pain and bleeding : laser surgery has less pain and bleeding. Laser rays are painless when repairing damaged nerves. In laser surgery, capillaries and blood vessels are burned without bleeding.

Hospitalization of the patient : After the traditional surgery, the patient has to be hospitalized for 1-2 days due to pain, general anesthesia and bleeding. In the laser surgery method, the patient is immediately discharged and goes about his daily activities.

Duration of operation : The duration of laser operation is less than 1 hour. Traditional surgery takes longer due to anesthesia, wound incision, drainage and dressing.

Cost : The cost of traditional surgery is much higher than laser surgery due to the duration of surgery, hospitalization of the patient, multiple dressings and drugs. It should be noted that all insurances cover the cost of laser surgery.

Transmission of disease : due to open surgery without laser, the possibility of transmission of infectious and blood diseases is higher in traditional surgical method.

Use of laser for skin beauty

Another use of laser in medicine is skin rejuvenation and beauty. To rejuvenate the skin and solve skin problems, the use of laser is cheap, fast and without side effects. The application of laser for skin beauty is:

Removal of light and dark vascular moles

Removing various skin spots such as freckles and tattoos

Treatment and reduction of body hair growth

Removing skin wrinkles

Removal of skin warts, scars, stitches and burns

Removal of localized obesity (cellulite)


Lasers are also used in gum surgeries, cell repair and anti-inflammatory treatments in the field of dentistry. The use of laser reduces the pain and high cost of dental treatments. Laser applications in dentistry include:

Accurate diagnosis of tooth decay

Prevention of tooth decay

tooth sharpener

Dental scaling

Eliminate tooth sensitivity

root canal

teeth whitening

Gum surgeries

Dental implant


Use of laser in ophthalmology

Another advantage of laser is the treatment of eye diseases and problems. The application of laser in the field of ophthalmology is:

Treatment of glaucoma

Treatment of eye bleeding

Fix retinal detachment

Treatment of visual impairment


“Laser has many other applications in the field of treatment, such as treating hemorrhoids , treating hair cysts , treating fissures , etc. In this article, we have mentioned small parts of the application of this technology.
