Lasers in Surgery
Abstract: The laser is gaining increasing popularity in the medical field because of its broad application, efficiency, and improvement in overall ease of the procedures in which it is used.. The laser can treat an enormous range of ailments. The chronic nighttime snorer can give those around him relief by a simple procedure with the laser. In dermatology, the laser can be used for removing moles, tattoos, birthmarks, treating wrinkles, and possibly destroying skin cancer. The once dreaded trips to the dentist may become less painful since the laser is helping to replace the drill and Novocain. The laser also is becoming increasingly popular in orthopedics for treating shoulder, knee, and back ailments. For women many gynecological problems ranging from infertility to endometriosis can be treated with the laser. For small, precise work the laser is indispensable such as in the eye. Unfortunately, since laser medicine is still rapidly developing, it has experienced its pitfalls in some areas like cardiology. Overall, the laser is an invaluable substitute for the scalpel of the past, and the laser's possibilities for the future are broad and promising.
Lasers in Surgery
The laser is creating a bloodless revolution. A laser works by using heat to obliterate cells. As it cuts, blood vessels are sealed, and tissue is sterilized. The laser is particularly useful in regions of the body that are difficult to reach. Many types of lasers are used in surgery, and the kind (gas, liquid, solid, visible, or unseen) varies based on the procedure.

Sometimes depending on the treatment deemed suitable, a thin layer is usually lifted away gently from the surface of the surface of the eye so as to enable the laser to access the layer below and correct the prescription with pinpoint accuracy. This layer is carefully set back in place and even at times it’s protected with a clear bandage contact lens for 3-5 days while the eye naturally heals. All these operations are normally carried out using bladeless laser technology in order to eliminate potential complications that may emerge and improve the results for every patient that is treated.

Now, several modern approaches to corrective eye surgery range from laser reshaping of the eye's surface to surgical insertion of artificial lenses to correct eyesight. In corrective eye surgery, laser energy reshapes the curvature of the eye's clear front surface, the cornea, to alter the way light rays enter the eye. Artificial lenses surgically inserted into the eye also can refocus light rays to sharpen vision. In the surgery process, lasers are utilized to operate on the cornea and fix the parts of your eyes that don’t work, so that your eyesight becomes improved. The whole process of corrective eye surgery usually takes only a few minutes, depending on the patient’s present state of health. No matter how bad your eye sight was, after finishing the eye surgery treatment your eyesight result in a better vision.
