Use this glossary of general eye terms for a better understanding of overall eye care.

Having astigmatism that needs correcting occurs frequently for both nearsighted and farsighted people.

Generally age-related, a cataract is a clouding of the lens of the eye that blocks light from properly passing through to the retina. A lens with a cataract will cause blurred vision.

A procedure in which the cataract is removed and replaced with a clear artificial intraocular lens implant (IOL) to improve vision.

The clear outer surface of the eye that plays a key role in vision by focusing light onto the retina.

Hyperopia is farsightedness. It’s a common type of refractive error where objects far away may be seen more clearly than objects that are near.

A method of cataract removal in which many of the manual aspects are performed with a laser rather than a hand-held tool for improved accuracy and precision. 

Corrective eye surgery that uses lasers to reshape the cornea. It can help reduce or eliminate nearsightedness, farsightedness, and/or astigmatism.

Also known as nearsightedness, a refractive error that causes distant objects to appear blurred. 

A surgical technique for cataract removal where the cataract is broken up and removed through a small incision using an ultrasonic probe. This is done before the artificial intraocular lens (IOL) is implanted.

The natural hardening of the eye's lens, which creates an inability to focus on nearby objects. Usually seen in people 40 and over.
