How is refractive surgery done?

Refractive eye surgery, also called PRK, is non-invasive vision correction used to improve the refractive condition of the eyes and minimize or completely eliminate dependency on lenses or glasses. Including a number of types of cosmetic or reconstructive surgical remodeling of the eye's cornea, including lens implants, lens augmentation or lens removal. Before, the majority of refractive surgery was performed in the doctor's office under local anesthesia. Today, however, more patients are opting for outpatient refractive surgery , which is performed at a shorter office visit and often at a lowered cost.

PRK is made to correct many different refractory vision conditions, including myopia (nearsightedness), hypermetropia (farsightedness) and astigmatism. Myopia, also referred to as nearsightedness, can cause blurry vision at close distance, whereas hypermetropia causes blurred vision at long distance. Astigmatism affects the central field of vision, near and far, with the condition referred to as astigmatism being most common in those with a cataract. Additionally, it may affect close distance vision.

PRK and other refractive surgery procedures can correct a number of different eye conditions. For myopia, the use of an astigmatism corrective laser enables the eye to focus light to the retina for improved vision. For astigmatism, or farsightedness, the use of a laser enables a person's eye to target light from the retina back to the optometrist's laser eye. For both conditions, the utilization of a laser enables better detection of close-up vision and greater distance vision. LASIK, a laser-assisted in situ keratomileusis, is a favorite elective procedure that corrects both myopia and hypermetropia.

Refractive surgery is a highly useful procedure for many who need the vision corrected in order to perform their jobs and hobbies comfortably. While the procedure is sometimes scary, especially for many who have now been suffering for decades, the end results greatly improve the standard of living for patients. Whenever you head to an eye surgeon, he or she will assess your overall situation and discuss the options which are available to boost your vision. While the decision may not be a simple one, with the aid of your doctor, you should be able to find the best means of your vision improvement.
