AblationThe process of removing tissue by applying energy pulses from the excimer laser onto the surface of the cornea, thus reshaping the focusing surface of the eye. |
AccommodationThis is the process that enables the eye to change focus from distance to near and allows us to read. It involves muscular activity within the eye as well as a change in the shape of the eye's natural lens. This process weakens with age and the result is the need to wear reading glasses starting in our 40's. See Presbyopia. |
AlgorithmFormula used by the computer manufacturers to control the pattern delivered by the laser to reshape the cornea. |
Astigmatic KeratotomyA procedure used to reduce astigmatism by placing small incisions, by hand, in the cornea. |
AstigmatismA condition in which the cornea is "out of round". The surface is not spherical like the surface of a standard ball but more angular like the surface of a football. |
BCVA (Best Corrected Visual Acuity)Usually refers to the best a person can see on the standard eye chart with their most accurate refraction in glasses or the phoropter testing equipment. |
CorneaThe transparent front of the eye through which light enters. It is similar to the crystal on the front of a watch. |
Corneal FlapA layer of tissue created by a microkeratome, under which the laser treatment is placed in the LASIK procedure. |
EmmetropiaThe term applied to the vision status of an individual when the eye is properly shaped and has "perfect" distance vision without correction. |
Epithelial ErosionTemporary loss of surface corneal cells, usually related to dryness or trauma. |
Fluctuating VisionA transient condition following most refractive surgery in which the patientÕs vision may vary a bit, day to day, until stabilization. In LASIK this is usually about two weeks. |
Foreign Body SensationA scratchy feeling that occurs whenever the corneal surface is temporarily disturbed, as in injuries or surgical procedures. |
HazeA type of healing reaction that causes cloudiness in the cornea following PRK or LASEK. It is related to the loss of BowmanÕs Layer in these procedures. |
Hyperopia (Farsightedness)Refractive error related to either a flat cornea or short eye length. The optical effect is that distant objects tend to be clearer than near objects. |
Myopia (Nearsightedness)Refractive error related to either a steep, or pointed cornea, or an eye of greater than usual length. The optical effect is that near objects are clearer than distance ones. |
NomogramsTables created by surgeons to adjust the laser for individual patient treatments. Based on the major variables of age and amount of correction required. |
Pseudo-Accommodative IOLMany intraocular lenses, due to complex optical properties, seem to have some ability to provide some accommodative effect even though they are not designed to specifically change position within the eye (see Accommodative IOL). |
Re-treatmentA term equivalent to "enhancement" but usually reserved for secondary treatments in laser corrections. |
Surface Laser AblationA category of vision correction surgery including PRK and LASEK. |
We feel it is very important for you to understand the different surgical techniques we use. You can learn more from our Video Library.
