Refractive surgical procedures are a safe and popular choice for those people seeking freedom from visual hardware. Refractive procedures are designed to eliminate or reduce the need for glasses or contact lenses.
These procedures correct refractive errors by changing the focus of the eye. Common procedures such as LASIK and PRK do this by reshaping the curve of the cornea (the clear front window of the eye) to move the point at which light is focused onto the retina (light-sensitive tissue lining the back of the eye). Procedures such as Conductive Keratoplasty (CK) use radio frequency energy to bend the cornea, and Intraocular Lenses (IOLs) place an artificial lens inside the eye to more accurately focus light onto the retina.
