Farsightedness can be corrected through Conductive Keratoplasty (CK). Nearsighted patients are not alone in benefiting from surgeries. LASIK can be done with the aid of a mechanical cutting tool, using all lasers or incorporating wavefront technology that measures how light hits the eye. There is some risk of suffering dry eye and other complications such as halos around bright lights until the flap fully heals. Unlike PRK, it only takes a few hours to gain sharper vision with LASIK surgery. It involves cutting a thin flap in the outer covering of the eye to reshape the cornea. With PRK, it only takes a few days for vision improvements to be realized. The FDA approved PRK in 1995 and it is still widely used early in the 21st Century. Photorefractive Keratectomy (PRK) became the first successful surgery to change the shape of the cornea through removing tissue. Laser correction surgeries offer a snapshot of evolution in eye surgeries. Thinner corneas with a high degree of myopia, for example, usually require a more invasive surgery to reshape the eye surface enough to improve vision. The state of the cornea is a determining factor in these surgeries.
These procedures correct how light entering the eye is processed – leading to much sharper vision in patients. Surgical techniques and tools have rapidly evolved over the past two decades to create procedures that are both safe and helpful.Ĭorrective surgeries for eyes now include everything from using lasers to reshape the cornea surface to inserting artificial lenses. Now an increasing number of eye surgery options have displaced glasses or contacts as the only solutions for healthy vision.Īdvanced technology has made it possible to reshape eyes and restore vision to healthy levels for many people from all walks of life. When contact lenses arrived on the scene, they offered a new practical solution for restoring vision. Eyeglasses have been a traditional solution for correcting vision problems for many centuries.
