Application of used lasers medical enabled to treat different organs like skin, hair and eye present in human body. Laser use energy beam that is used to dissolve molecular bonds present in tissues and it ensures that with less constraint various branches of medicine can be explored. Laser treatment is used for remote surgery, cosmetic surgery and surgical procedure. Technology associated with laser enabled to treat acupuncture and also acute and chronic pain. It is used to cure and reduce inflammations and also used for treatment of hair loss, teeth and eyes. Energy beam is directed towards acupuncture dots without causing any pain. Recent advances in laser technology made to use ultrashort pulses that enables to reduce the interaction time and also minimizes the side effects cause due to irradiation on tissue layer.

Some of the advantages associated with use of laparoscopic lasers that are directed by computer decreased the requirement of open surgeries. Health care benefits include reduction in healing time, cross infection is avoided and costs were reduced. Surgical procedures involve use of laser beam for sterilization effect and it vaporizes fungi, bacteria and viruses leading to reduce the cause of infections.

 Food and Drug administration (FDA) approved the application of laser treatment to diagnose and treat the problems associated with dental like teeth whitening and decaying. There are different types of lasers used in medical field and most commonly used is soft tissue layer surgery that is mainly focused on oral,  dental, maxillofacial and neurosurgery. Laser treatment is used for hair analysis by detecting elements like lead and mercury etc. Laser is used for eye surgery which involves correction of problems associated with vision by constant decreasing the need for eye glasses. Refractive based surgery is focused on cornea reshaping in order to achieve better optimization of light in the eye thus result in providing image which is clear and transparent.

Other applications of laser in the field of medicine include analysis of stone formation in urine and cosmetics. One of the breakthrough’s in the field of medicine is use of laser for medical treatment and surgery for example refractive based surgery, tooth decay surgery and also used for treatment of cancer. Endoscopy, excision, phototherapy and tumour coagulation procedure requires application of used lasers medical and it is also useful for treatment of prostate and urinary related infections. Advances in laser technology made use of laser tweezers for fast screening of cancer and to trap microorganisms and DNA.
