Laser eye surgery is the most usually experienced procedure to correct vision problems caused by refractive errors, including myopia, hyperopia and astigmatism. Laser eye surgery has also been used to correct presbyopia, which is part of normal aging and can be corrected by using reading glasses.
All of these conditions are caused by problems with the way the eye focuses an image on the retina, which is the light-sensitive layer at the back of the eye. A huge part of the eye's ability to focus depends on the shape of the cornea, the clear front surface of the eye.
During laser eye surgery, a surgeon uses a laser device to make enduring changes to the shape of the cornea. The laser used most often is the excimer laser, which creates a ray of ultraviolet light to turn to vapor tissue. Surgically changing the shape of the cornea can correct mild to moderate refractive errors in most people.
The heat generated by the laser keeps the surgical site free of germs and reduces the risk of infection. Because a smaller incision is required, laser procedures often take less time than traditional surgery. Sealing off blood vessels and nerves reduces bleeding, swelling, scarring, pain, and the length of the recovery period. The Laser surgery technique takes less than 30 minutes to achieve and it is very effective.
The technical advancements combined in the Laser method eliminates the clinically important risks leading to visual impairment after a surgery. Although a small number of patients experience mild after their LASIK procedure, many people say that their nighttime vision improves after the procedure. For people who wear contact lenses, end-of-day dryness may also cause fuzzy dark vision.
Without having reflections and a poor refractive surface because of dryness, many post LASIK patients actually see better at night. Some patients with high stages of myopia or astigmatism advance extra lines of vision after LASIK. These types of refractive errors are best modified on the corneal surface and often increase a patient’s transparency after surgery as opposed to only partly altering them with glasses or contacts that move with each flash.
In addition to improved straight-ahead vision, many of my patient’s remark how much better their peripheral vision has become since they no longer wear glasses. Glasses do not wrapper around the eyes, so exterior vision is unsure if the enduring turns head. Once the glasses are gone, peripheral vision is clear as well. Some patients say their allergy symptoms improve after treatment. They claim fewer headaches and less pain without glasses sitting on their nose. Contact wearers claim less eye irritation and redness because they don't require putting contact lens in their eyes. LASIK is an optional process, reserved for patients who want to reduce or remove a requirement on spectacles or contact lenses. We will support you at all time.
