REFRACTIVE SURGERY Refractive surgery offers patients an alternative to glasses and contact lenses. By altering the contour of the front surface of the eye, contemporary refractive surgery can reduce or eliminate your need for prescription eyewear. The purpose of this report is to maximize your understanding of this safe and effective technique. HOW THE EYE WORKS The human eye functions much like a camera. However; despite decades of advancements, the image-capturing capabilities of the camera falls far short of the vision capabilities of the human eye. The miracle of vision begins as light strikes the transparent outer-layer of the eye, the cornea. The cornea begins to refract or bend this light. The final bending of light is accomplished by the variable focus lens inside the eye. This refracted light determines the final focus or the clarity of the image on the back of the eye, the retina. Think of the retina as a thin layer of nerve tissue that functions much-like the film in a camera. This focused image on the retina is chemically translated from light energy into nerve impulses and sent to the brain for final processing. The clarity and sharpness of the image formed by the cornea and lens onto the retina determines how clearly the eye can see.
