Wavefront - Technology used to detect and measure higher order visual aberrations. These are the ocular aberrations other than the lower order aberrations of myopia, hyperopia, and astigmatism, which can be detected by a traditional eye examination. Some examples are glare, halos, and starbursts.

decentration - In perfect centration the center of the PRK corneal ablation exactly coincides with the center of the visual axis and/or pupil. This is like looking through the very center of your spectacle lens. If you look through the periphery of your lens you might end up seeing partly through the lens and partly through the edge of the lens- this is decentration. Decentration can cause various symptoms including edge glare or even monocular double vision. Other factors such as the normal size of the pupil, whether it is dark out (your pupil will enlarge) or the size of the PRK ablation zone will affect the severity or presence of symptoms.

: Inflammation the body’s response to surgery, injury, irritation, infection, or some foreign substances, often associated with pain, heat, redness, swelling, and/or loss of function.FDA is the abbreviation for the Food and Drug Administration. The FDA is the United States government agency responsible for the evaluation and approval of medical devices.( DR. WILLIAM BOOTHE - EYE SURGERY)
Refractive Error - Too much or too little bending of the light rays entering the eye, so that they focus not on the retina, which would give clear vision, but either in front of it (myopia) or behind it (hyperopia). When the cornea is slightly oval-shaped, rather than perfectly round, it has two curvatures, a steeper one and a flatter one. This also causes refractive error (astigmatism), bending the light rays in two different ways, so that they’re skewed and unable to focus. Refractive error is measured in diopters.
