LASIK eye surgery is at the forefront of bringing people better vision. While this treatment has been available for many years, some patients considering the treatment become overwhelmed by LASIK terminology.
This page offers simple definitions to LASIK terms so anyone can get a sense of what the procedure is all about.
Acuity: The eye’s ability to see in detail
Astigmatism: Blurry vision caused by an oblong, egg-shaped cornea
Best corrected visual acuity (BCVA): The best level of vision a person can get with the use of corrective lenses
Bilateral LASIK: LASIK treatment performed on both eyes
Bladeless LASIK: LASIK treatment in which the surgeon uses an Intralase or other femtosecond laser to make the flap in the cornea
Cataract: A natural cloud in the lens of the eye that causes loss of vision
Corneal epithelium: The outermost layer of cells in the cornea
Custom LASIK: Computers create a three-dimensional model of a patient’s eye to create a highly specific and detailed plan for correcting vision
Diopter: An optical measure of vision correction
Excimer laser: A laser that uses ultraviolet light to perform LASIK by reshaping the cornea
Farsightedness: A vision disorder that causes better vision of faraway objects and difficulty in seeing nearby objects
Keratectomy: Removal of the corneal tissue, which completes the LASIK procedure
Lid speculum: A medical instrument that holds the eyelids open during eye surgery
