Visual Acuity - Clear vision with sharp details. Also called central vision.Visual Field - The complete area that’s visible when the eyes are looking straight ahead.
Vitreous Detachment - (VIT-ree-us) Separation of vitreous humor from the retina. If the gel pulls on the retinal surface, it can sometimes cause it to tear, which could lead to retinal detachment. Vitreous detachment occurs more often in older people and those with certain diseases such as diabetes.

Vitreous Fluid - The jelly-like fluid that fills the main part of the eye, between the lens and the retina. It’s clear so as to give light rays an unobstructed path to the retina, and to keep that clarity, it contains phagocytes, cells which ingest and destroy foreign matter.Vitreous Humor - The transparent gel that fills the space inside the eye behind the lens and in front of the retina.

DR WILLIAM BOOTHE - DALLAS: Contact Lens Assisted Pharmacologically Induced Kerato Steepening - A way to undo overcorrection in laser eye surgery (LASIK, PRK and RK). A tightly-fitting contact lens is placed on the eye and anti-inflammatory eyedrops are used. The goal is to make the cornea more steep, after it’s been made too flat.
Contact Lens Disinfectant - A solution for removing bacteria and micro-organisms from contact lenses.

Coma - A higher order aberration which makes points of light look like comets with blurry tail-like smudges. It can be diagnosed and treated with wavefront-guided LASIK procedures.
Complex Wavefront Retreatment - An off-label use of the excimer laser to do corrective secondary surgery after the original wavefront-guided surgery has left the patient with higher-order aberrations.
LASIK EYE - Dr William Boothe
DR WILLIAM A. BOOTHE - DALLAS LASIK: Legal Blindness - A definition of blindness which enables a person to apply for government disability benefits. It can be either a visual acuity of 20/200 (or worse), with corrective lenses, in the better eye, or tunnel vision in the better eye of 20 degrees in diameter. This level of blindness is severe, but does not necessarily prevent a person from functioning at all.
Corneal Transplant - Surgery to replace the cornea, the clear front area of the eye. Corneal tissue comes from a donor and since the cornea has a small blood supply, there is little risk of rejection, and the new cornea can function very well for years. A corneal transplant can be done to treat Keratoconus, Fuch’s Dystrophy, or damage from a severe infection or injury. It’s a painless outpatient procedure.

Central Ablation Zone - The ablation zone is the area of the eye treated by the laser in LASIK surgery. Around it is the transition zone, where the treated area gradually merges with the original corneal surface that lies outside the ablation zone.
Central Island - An area of the laser-treated part of the cornea which is erroneously not treated, so that its level remains microscopically higher than the surrounding treated surface. The term island describes its appearance. It causes diplopia (double vision).
