Vision-correction includes several surgical procedures that are designed to eliminate or reduce your need for glasses or contact lenses. If your eye does not correctly focus light, it has a refractive error. By changing the focus of the eye, vision-correction surgeries correct refractive errors and improve your vision. For this reason, they are also called “refractive surgeries.”
These two types of vision-correction surgeries use lasers:
- Laser-Assisted in situ Keratomileusis (LASIK)
- Photorefractive keratectomy (PRK)
Some patients are not good candidates for laser eye surgery. But there are alternatives. One uses an artificial lens called a phakic intraocular lens. It is placed inside the eye to more accurately focus light onto the retina. Refractive lensectomy, a similar option, involves removing the crystalline lens and replacing it with a lens implant.
