How has the use of lasers been beneficial to medicine?
The term Laser is an acronym that of Light Amplification by Simulated Emission of Electromagnetic Radiation. These lasers have many applications in many different industries around the world. However, with new uses constantly being developed lasers are proving to be extremely beneficial to the world of medicine in particular. From laser imaging and disease diagnosis to curing and treating illnesses that were not curable previously. Medical lasers have already saved many lives worldwide.
Lasers have been recently used for purposes of cosmetic surgery. They can be used to remove wrinkles, removing birthmarks or discolorations, as well as many other developing applications. Lasers have only recently been used in such ways and many new treatments are being adapted.
However, lasers are also being used for more serious uses in medicine. Lasers are now being utilized in optometry and eye surgery to a great success. The unique characteristics that lasers provide have created many new treatments, for once incurable vision ailments. As t...
In the end, regardless of the scientific methods that could be used to treat different diseases and more specifically retinal degeneration, many studies should be conducted determine the potential clinical application of photobiomodulation with NIR for treatment of different injuries and disorders.
Over the years, surgery has made tremendous progress while changing human perspective; viewed as “no more science than butchery” a couple of centuries ago to now considered to be a solution for many health care problems threatening humans, like cancer, heart disease and kidney failure. Nevertheless, surgery has not been perfected to a level that provides successful results every time it is performed on patients. For example, surgery done to remove tumors in cancer patients result in only 45% of individuals to be cured. However, in order to be successful, the surgical procedure has to be carried out incredibly precisely and incomplete removal of tumors can decrease survival rate. Therefore, surgeons have to be able to recognize diseased tissue and distinguish it between healthy tissues. But even with the use of radioactive tracers and visuals, surgeons are not able to identify the exact site of the unhealthy tissue and its boundaries. Thus, almost 40% of the time cancerous cells are left behind because even the best qualified surgeons are not successful at the nanotechnological scale of tissue.
The word oscilloscope is a word that combines from Latin and Greek language. The first part “oscillare” derives from the Latin words meaning to swing backwards and forwards. The second part comes from Classical Greek “skopein” means to observe, aim at, examine, from which developed the Latin ending “scopium”, which has been used to form names for instruments that enable the eye or ear to make observation.
Optometry involves of a combination of intricate practical skills and academia allowing the improvement of an individual’s vision as an outcome changing their quality of life. I would feel privileged to gain the opportunity to study Optometry enabling me to improve the ocular health and vision of others as it would be a valuable contribution to the society.
My interest into becoming an optometrist had begun when I was in high school; it happened in an unconventional way. It was not through watching videos, or someone explaining to me what optometry was, but rather, seeing the power of it firsthand. There was a point in my life where I felt emotions that I was unable to comprehend at the time. Seeing a family member on an operating table was the most petrifying moment that I have gone through, especially when the person on the table was my father. My father had to get a chalazion removed from his right eyelid. The doctor told my family that my father would be susceptible to certain health risks because of his diabetes and the severity of his cyst. This procedure was the hardest thing I have had to deal with in my life because it made me feel helpless. Usually, when my dad needs help he always asks me, but this time I could not do anything. It is interesting to think that something so small had such a big affect on my life.
The time required for recovery and recuperation in laser treatment is less than that required for surgery.
Erbium or YAG laser which is of precise wave length penetrates into the skin. As the scattering of the YAG lasers are less, the normal skin is left unaffected.
Light energy cannot be created or destroyed; it can only be converted from one form to another. Just like how a pendulum eventually stops due to air resistance, the laser should continue to travel indefinitely unless the light is either absorbed, reflected or refracted. Harnessing a lightsaber would be extremely unwieldy- slight carelessness could potentially sever off your own toes. According to the movie, the lightsaber consists of a “plasma blade” which is powered by a “kyber crystal” and emitted from a “metallic hilt”.
Laser is an acronym used for Light Amplification by Stimulated Emission of Radiation. Laser treatment is a procedure used to cure skin problems with a strong beam of light. Experienced cosmetologists and dermatologists use this new technology to cure many ailments.
LASIK eye surgery, also called, laser-assisted in-situ kerkatolmileusis, is a procedure which corrects vision problems and eliminates the need for glasses or contact lenses. It’s a type of eye surgery that changes the shape of the cornea using a laser. With LASIK eye surgery, the main goal is to “bend light rays to focus more precisely on the patient’s retina” and to produce clearer and sharper vision.
The movie “Spotlight” directed by Tom McCarthy is a film about a true situation that had happened in 1976 involving a catholic priest molesting a child, even after the situation the assistance director attorney was telling the cops to not let the press receive any of that information. Eventually in 2001 the Boston Globe had hired a new editor Baron. Baron then reads a Globe column about a lawyer saying that the Cardinal Bernard Law had known that a priest named John was molesting children and nothing was done to stop him, which John tries to get the small group of journalist to research about the case. Later on they eventually start trying to get an article posted but in order to do that, they must get a lot more research done. Continuing on
Oftentimes, a person can look at an image and draw a conclusion about it, only to find out later that he or she was incorrect. This phenomenon is due to what is called an optical illusion, in which an image is perceived incorrectly to be something else. This leads to the questions, why do optical illusions occur, and what can be done about them?
An oscilloscope is an electronic test instrument that is used to observe an electronic signal, typically voltage, as a function of time. In other words, it is a voltage versus time plotter. Oscilloscopes come in two basic types, analogue or digital, and support various features and functions useful for measuring and testing electronic circuits. An oscilloscope is a key piece of test equipment for any electronics designer.
As you can see lasers are a very useful and important tool which is why I have
Optometry is unique when compared to a field such as general medicine; as a field, optometry is relatively new to many people. The importance of optometry has moved beyond simply helping patients see better, to maintaining the health of the eye and working to screen for many other health conditions. Because its importance is becoming more understood and well known to the general public, the number of patients seeking treatment is growing drastically. As stated above this drastic growth is not only increasing the number of patients but also the number of places optometry is being practiced as well as changing the demographics of the patients being see...
