Medical itself means or relates to treatment or injuries in a person. What is Laser? Laser is a device which emits light and emits electromagnetic radiation. This uses a process of optical amplification .The light emitted is focused on a particular spot thus enabling cutting with help of laser lights which have the same frequency and wavelength. It covers a very limited area with light on a spot which is magnified or amplified and thus helps in surgery or cutting or stones etc.
Medical devices which use this kind of focused light force to remover tissues or for treatment are called medical lasers. Lasers were first used to remove a tattoo in 1960. Since laser uses focused light which is magnified, it is excrementally useful in surgeries especially for the eye surgeries which are corrective in nature. PKR is a corrective eye surgery. It was used to treat myopia by removing a small portion of the cornea using laser. Do you know and it’s really amazing to know that people are actually awake during a laser surgery. Local anesthetic drops are administered and so one does not feel any pain during this Lasik surgery. Numbing drops reduces the urge to even blink.Farsightedness can be corrected by using Lasik, PKT or Lasik which depends on how the eye is prepared for the laser treatment. All these have high success rates and ones vision can be corrected quite effectively. Think of vision without using glasses or lens .What a relief it will be to have the natural eyes as it is. Contact lenses normally have the capacity to change the natural shape of the cornea, hence if one is wearing contacts the surgeon normally tells the patient to stop wearing them for a period of time before a measurement is taken for the laser eye surgery. Lasik is safer alternative to Lasik due to minimal discomfort and quicker recovery.
Syneron used medical lasers are produced. Syneron is a company that develops devices for cosmetic surgery for procedures like hair removals or wrinkle treatment. It also develops devices for betterment of skin appearance, acne treatment and the like. These procedures are non invasive. Dermatologists, Plastic surgeons, Cosmetic physician, aestheticians, Medical spas all purchase these devices from Syneron Medicals. Body shaping devices are also available with Syneron medicalsmany different gases function as a laser media. We have carbon dioxide laser which is the most efficient commercial gas laser. However semi conductor diode lasers are most common lasers used today.
