Refractive surgery for vision correction has made many significant advances since its start as radial keratotomy. The concept was first used in the early 1960’s by Sato in Japan. However, the original procedure did not work for most people. It is the earliest form of vision correction surgery. Over time in the 1970’s the procedure was corrected by the Russian, ophthalmologist Fyodorov and it was performed in the United States of America in 1978.
Today, several different options exist to help the majority people who wear glasses or contact lenses reduce their dependence on their corrective lenses. Refractive surgery is mostly elective and cosmetic. However, most people today are depending on the laser vision correction procedure to correct their vision.
What is laser vision correction? Laser vision correction can be used to treat myopia, myopia with astigmatism, hyperopia with astigmatism, or astigmatism alone. Not every person requesting laser vision correction is a candidate for surgery. Some factors that may prevent a candidate from not being able to get this type of surgery include a person with very high refractive errors, certain ocular diseases, and certain medical diseases.
What is the eligibility for getting the laser vision correction? The main criteria includes that the individual has to be of 18 years of age or older for myopia or hyperopia. Although, for astigmatism, the individual should be of 21 years of age or older. The individual can not have any eye problems such as keratoconus, herpes keratitis, unstable refractive error, or corneal disease/scarring, or cataract/glaucoma. Also, individuals with medical problems such as collagen vascular disease (lupus), autoimmune diseases, immunosuppressive diseases such as AIDS, or pregnancy or breastfeeding, and no diabetic retinopathy if diabetes is present may not be allowed for laser vision correction. There are many health factors that are involved. It would be a risk to get this type of surgery done with such health conditions.
