Refractive Surgery: Improving Your Vision - A Photorefractive Keratotomy (PDK) Or Lasik
Refractive eye surgery, also called PRK, is non-invasive vision correction used to boost the refractive condition of the eyes and minimize or completely eliminate dependency on contact lenses or glasses. This includes many different ways of cosmetic or reconstructive surgical remodeling of the eye's cornea, including lens implants, lens augmentation or lens removal. Before, many refractive surgery was performed in the doctor's office under local anesthesia. Today, however, more patients are choosing outpatient refractive surgery , which is completed at a shorter office visit and often at a lesser cost.
PRK is made to correct a number of 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 frequent in individuals 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 utilization of an astigmatism corrective laser enables a person's eye to target light to the retina for improved vision. For astigmatism, or farsightedness, the usage 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 use of a laser enables better detection of close-up vision and greater distance vision. LASIK, a laser-assisted in situ keratomileusis, is a popular elective procedure that corrects both myopia and hypermetropia.
Refractive surgery is a highly useful procedure for many who need the vision corrected to be able to perform their jobs and hobbies comfortably. While the task is sometimes scary, especially for individuals who have now been suffering for decades, the finish results greatly enhance the quality of life for patients. When you go to a watch surgeon, he or she'll assess your present situation and discuss the options that are available to boost your vision. While your choice might not be an easy one, with assistance from your doctor, you ought to be able to find the best process of your vision improvement.
