Laser Eye Correction Information
Laser eye correction is a corrective surgery that uses a laser to form a tiny flap in the cornea and make changes to the shape of the cornea. Lasik Surgery is the most commonly used Laser Eye Surgery these days, and thousands of people per year use it to successfully treat Problems with Eyesight like Nearsighted Vision, Hyperopia also known as "farsightedness" or "long sightedness" vision, and Cataracts. Most people who use Laser Surgery for Eyes no longer need to wear Prescription Glasses, although in some rare cases there is the need for a second surgical procedure to completely fix the problem. Before Lasik came about, the excimer laser was the most popular tool for laser eye correction, but in 1991 a Greek scientist created the Lasek procedure, which is an acronym for laser in situ keratomileusis. The “situ” is a flap in the Cornea, and the “keratomileusis” is the cornea, so basically the name stands for a laser in a flap in the cornea. During the procedure, the Laser Eye Surgeon will cut a miniscule flap in the outer layer of the cornea, leaving one side connected to serve as a hinge for the flap. This is either done with the use of a laser or with a small metallic scalpel, although these days’ lasers are more commonly used. The surgeon will then peel back the little flap so that he can get to the internal tissue of the cornea. The laser will then reshape sections of the cornea to correct refractive errors that lead to Vision Problems.
Every laser pattern is mapped out before the procedure begins and tailored towards each individual patient. The patient needs to be awake while this is happening, which isn't exactly a pleasant experience, but the eyes need to be open and focusing for the procedure to work. Most surgeons will apply an anesthetic eye drop so that the eye loses most of its feeling temporarily, and some clinics will prescribe a one time use of a sedative like Valium to calm the patient. During the laser eye correction, the targeting sensors on the laser will track the eye's movements 400 times per second, allowing the laser to remain on the target zone even if the patient is moving his or her eye around. The laser will essentially vaporize sections of the corneal tissue. After the surgery is completed, the flap in the outer layer of the Cornea is repositioned and the patient is given antibiotics to counteract any possible infections. Laser Vision Corrective Surgery should always be a last resort, but if you have no other options to Protect Your Eyesight, it can be very beneficial. Sometimes Lasik Laser Eye Surgery is required to fix refractive errors, and other times it's an elective Laser Cosmetic Eye Surgery so that the patient doesn't have to continue wearing Prescription Glasses or Contact Lenses for the rest of his or her life. If you're thinking about getting laser eye correction surgery, talk to your doctor about the possible Laser Eye Surgery Risks involved, and then weigh the benefits against those risks to decide for yourself if it's worth it.
