Like most medical procedures LASIK comes with a colorful diction that can go a long way in enabling one better understand this highly effective refractive laser correction procedure.


Acuity: the ability of an eye to see fine details.

AffiliatedOptiView doctors: Highly qualified physicians who form the larger OptiView family and collaborate with in-house OptiView Vision Center surgeons to give their patients the best care possible.

Anesthesia: a drug that causes numbness thus preventing pain.

Astigmatism: This term describes an eye that has an oddly shaped cornea making both near and distant vision very difficult for the individual.

Best corrected visual acuity(BCVA): the best possible vision clarity that a person can acquire with the help of correcting lenses usually measured in snellen on an eye chart.

Bilateral LASIK: Surgery performed on both eyes at the same time.

Bladeless LASIK: A form of LASIK where the surgeon uses the IntraLase laser to form the protective flap.

Cataract: A cloudiness of the natural lens that impedes vision.

Cataract surgery: the removal of a cloudy natural lens during surgery and replacing it with aintraocular lens implant.

Cornea: the transparent part of the eyeball that aids in focusing light.

Cornea flap: the first step in LASIK that involves creating a protective flap on the cornea.

Custom LASIK: A procedure that uses wavefront technology to map an individual’s eyes and the relay this information to the laser for the appropriate correction.

Diopter: a unit of measurement used to describe the light bending properties of an optical system.

Dry eyes: A deficiency in the production of tears.

Excimer Laser: A laser used to correct vision by using ultra violet light.

Farsightedness (hyperropia): Where the eye is too short to focus light properly on the retina.

Flexible Spending Account (FSA)An employer-provided health savings account.

Health Savings Account (HSA): An account created for people who are currently covered under a high deductible health plan (HDHP).

Higher-Order Aberrations:Imperfections in the visual system that cause decreased night vision, glare and halos.

Health Reimbursement Account (HRA): An employer-funded plan that will reimburse employees for out-of-pocket medical expenses not covered by the company’s standard insurance plan.

Intraocular: Within the eye.

IOL (Intraocular Lens): An artificial lens used to replace the natural crystalline lens of the eye.

Iris: The colored portion of your eye that expands and contracts to allow more or less light into your eye.

Keratectomy: A process in which tissue is removed to change the corneal shape

LASIK: Also known as Laser-In-Situ Keratomileusis, LASIK is the most frequently performed elective health care procedure in North America. A protective corneal flap is created and gently lifted by the surgeon and a laser beam used to correct the prescription.

LASIK Candidate: A person who meets a series of criteria that make him or her an ideal candidate for the LASIK procedure.

LASIK Consultation: A thorough eye screening and discussion that is used to determine if an individual is a good candidate for LASIK.

LASEK (laser epithelial keratomileusis): Aprocedure similar to traditional LASIK but differing in how the corneal flap is created.

Lens: located behind the iris whose primary function is to allow the eye to focus on objects at distance.

Lid Speculum: An instrument used to hold the patient’s eyelids apart.

Lower-Order Aberrations: Which include myopia, hyperopia and astigmatism.

Microkeratome: A surgical instrument that uses a blade to make the corneal flap.

Monofocal Lens: A lens implant that allows vision at one specific distance.

Monovision: A procedure in which one eye is fully corrected while the other one is left alone.

Multifocal Lens: An intraocular lens that provides clarity of vision at more than one distance.

Nearsightedness (Myopia): Causes one to see close objects better than distant objects.

Night Glare (Halos): when one sees a halo around lights at night.

Off-label Use: Where doctors prescribe a medication or procedure for use other than for its indicated purpose.

Ophthalmologist: A medical doctor specializing in the diagnosis and treatment of eye diseases.

Optician: A specialist who trades in visual correction instruments.

Optometrists: A doctor who is trained to diagnose and treat common vision problems.

Over-Correction: A side effect that involves the eye over responding to laser correction.

Presbyopia: A failing visual clarity that comes with age.

Post-Operative: The healing period after the LASIK surgery.

PRK (Photorefractive Keratectomy): Similar to LASIK but involves the removal of the epithelium.

Pupil: The hole in the center of your iris.

Retina: Nerve tissue that lines the inside of the eye and acts like a film in a camera.

OptiView Vision Center’s Advantage Program: A savings program available to members of particular health insurances.

OptiView Eye Surgeon or OptiView Vision Center LASIK Surgeon: Surgeons who perform LASIK at OptiView’sVision Centers.

Toric Lens: A lens designed to correct astigmatism.

Uncorrected visual acuity (UCVA): best vision achievable without correction.

Visual Acuity: Sharpness or clearness of vision.

Wavefront Analyzer: A specialized technology designed to create a 3-D map of the eye’s visual system.
