Accommodation
– is the ability to quickly change focus to see objects
at distances up-close, far away and everything in between.
Presbyopia usually becomes significant in a person's mid-forties.
Apodization –The gradual reduction
or blending of the diffractive step heights. The application
of apodization to intraocular lenses is a patented process
by Alcon and can only be found in the AcrySofR ReSTOR
IOL.
Cataract – A "clouding"
of the lens in your eye. As light passes through the cataractous
lens, it is diffused or scattered. The result is blurred or
defocused vision.
Crystalline lens – The eye's natural
lens. Transparent, biconvex intraocular tissue that helps
bring rays of light to a focus on the retina.
Intraocular lens (IOL) – An artificial
lens that replaces the eye's clouded.
Monofocal IOL – An artificial lens
that provides patients with only one focal point, most commonly
distance, thus leaving patients dependent on glasses for near
activities. Currently, this is the most commonly implanted
artificial lens.
Presbyopia – Condition in which there
is a diminished power of accommodation arising from loss of
elasticity of the crystalline lens, as occurs with aging.
