LASIK is a type of refractive eye surgery that is used to correct conditions such as astigmatism, myopia, or hyperopia. This type of surgery is also called laser vision correction or laser eye surgery. This is often done by an ophthalmologist who will use a microkeratome blade or laser to reshape the cornea of the eye in order to improve vision. For most, this surgery is able to provide a lasting alternative to wearing contact lenses or eyeglasses.
LASIK is very similar to PRK as well as LASEK. Every one of these surgeries represents an advancement over radial keratotomy, the first refractive procedure invented. For those who have moderate to high myopia, or those who have thin corneas, an effective alternative are phakic intraocular lenses. In the last year, over 8 million people in the United States have had laser eye surgery and since 1991, over 40 million people have had it.
NICE, the National Institute for Health and Care Excellence, has considered the evidence regarding the risks and benefits of refractive surgery and has determined it to be safe and effective. Most refractive surgeons take extra precaution to ensure that their patients are able to fully understand the benefits and even potential risks of having laser eye surgery.
Based on an analysis from the American Society of Cataract & Refractive Surgery, which examined over 3000 peer reviewed articles from international clinical journals, it produced a patient satisfaction report from which showed that refractive eye surgery satisfaction rates range between 92% and 98%.
After having surgery, the patient will be given anti-inflammatory and antibiotic eye drops, which will be used for a few weeks after the surgery. Those who have the surgery will need to rest and wear dark glasses in order to protect their eyes from bright lights and in some instances protective goggles may be used to keep a person from rubbing their eyes while sleeping and to help reduce dry eye. After this, the patient is required to use artificial tears and prescription drops to aide with healing.
