Lasik Terms and Definitions
The following definitions were taken from lasikplus.com
- - Acuity refers to the sharpness or clarity of your vision.
- - The cornea is the transparent front portion of the eyeball that covers the iris and pupil; it is continuous with the sclera.
- - The corneal epithelium is the thin, protective layer encasing the eyeball. Prior to LASIK eye surgery, the epithelium must be lifted or polished away to expose the underlying cornea. The epithelium is regenerative and heals quickly.
- - A diopter is one whole number on a prescription. The number of diopters on your prescription represents how much correction is needed to normalize your vision. The more myopic or hyperopic you are, the higher your prescription will be represented in diopters; or rather the farther away from zero your prescription will be.
- - An excimer laser refers to a cool laser. Excimer lasers use cool beams of ultraviolet light to evaporate corneal tissue during vision correction.
- - Farsightedness is another name for Hyperopia or Hypermetropia. Many Farsighted patients have difficulty seeing things up close, and often have crisp-acute distance vision.
- - Many Hyperopic patients have difficulty seeing things up close, and often have crisp-acute distance vision.
