Eyeglasses have been a traditional solution for correcting vision problems for many centuries. When contact lenses arrived on the scene, they offered a new practical solution for restoring vision. Advanced technology has made it possible to reshape eyes and restore vision.
Surgical techniques and tools have rapidly evolved over the past decades to create procedures that are both safe and helpful. Corrective surgeries for eyes now include everything from using lasers to reshape the cornea surface to inserting artificial lenses.
Types of Eye Surgeries
Photorefractive Keratectomy (PRK) became the first successful surgery to change the shape of the cornea through removing tissue. The FDA approved PRK in 1995 and it is still widely used.
LASIK followed on the heels of PRK. It involves cutting a thin flap in the outer covering of the eye to reshape the cornea. Unlike PRK, it only takes a few hours to gain sharper vision with LASIK surgery. There is some risk of suffering dry eye and other complications such as halos around bright lights until the flap fully heals.
Nearsighted patients are not alone in benefiting from surgeries. Farsightedness can be corrected through Conductive Keratoplasty (CK). It uses a small probe and low heat radio waves to create spots around the cornea periphery. CK steepens the cornea to give patients better near vision.
Eye Surgery Considerations
Our eyes change as we age, so some corrective surgeries are not a good option for everyone. People under 21 for example, are not good candidates for laser eye surgeries because their eyes change rapidly as their bodies are growing.
Health also factors into eye surgeries. If you have diabetes or other medical conditions that impact eyesight, certain eye surgeries may pose serious risks.
