Deficiency in the vision can be corrected by spectacles or contact lenses. Many jobs and careers demand uncorrected normal vision. Youngsters are unable to take up many careers such as Cine, TV Artist, Models, Military Services, Police, Fire Fighters, Railways, Drivers, Navy, Air Force, Industrial Employment, Sales Careers, Drama, Theaters, Sports activities, Swimming, Etc. Young ladies face severe problems in getting marriage proposals.
To overcome these deficiencies glasses were invented in 13th century. Today contact lenses are very popular but they can only hide the ugly glasses but can not cure the problem. In the late 1970 Dr. Fyderov from USSR invented a surgical procedure known as Radial Keratotomy (RK) to correct low to moderate degree of myopia. RK became very popular worldwide. During the course of time many other techniques evolved in refractive surgery. Recently the use of Lasers to rectify abnormality of the shape of cornea and to correct vision have become tremendously popular. The refractive surgery today has scaled to the heights of safety, precision and accuracy and has become the fastest developing science in the world of Opthalmlogy.
