There are more than 24 million Americans aged 40 and older who have cataracts,
Prevent Blindness America. The condition, which affects primarily aging adults, is the leading cause
of blindness in America.
In order to educate the public and raise awareness about
cataracts, symptoms and
cataract treatment options, Prevent Blindness America declared June as Cataract Awareness Month.
What are cataracts?
In a healthy eye, light travels through the pupil of the eye, where it
is focused through the clear lens onto the retina. The lens, which is
made mostly of water and protein, can develop clumps of protein with age.
These protein deposits are what cause the lens to become cloudy. Mild
clouding of the eye may not affect vision much, but when a majority of
the lens becomes clouded, that is when serious vision problems develop
and treatment becomes necessary.
In most cases, cataracts are related to normal aging. However, there are
cataracts that can develop from other causes.
Congenital cataracts: Developmental or congenital cataracts can develop even in infants or children.
This type of cataract is typically associated with genetics or with birth
defects, though in some rare cases, there is no clear cause of the cataracts.
Cataracts from disease or medication: In some cases, cataracts may be caused by disease, such as diabetes, or
by a previous eye surgery. Excessive use of steroid medications to treat
other medical conditions may also lead to the development of cataracts.
Traumatic cataracts: A traumatic injury to the eye may also cause cataracts to develop. In some
cases, these cataracts will develop soon after the injury, while in other
cases they may take months or even years to develop.
Signs and symptoms of cataracts vary based on the severity of the cataracts.
If the cataracts remain small, they may not affect vision much at all,
but the larger and denser the cataracts, the more they will affect vision
cataract surgery for treatment.

What are the treatment options for cataracts?
Once cataracts begin to develop, there is no way to make the lens clear
again. Cataracts will steadily limit a person’s ability to simple
tasks such as seeing street signs, reading a book or driving at night.
In order to restore vision that has been lost due to cataracts, a patient
must undergo cataract surgery, during which the clouded lens is removed
and replaced with an artificial lens. Unlike other eye conditions, treating
cataracts isn’t urgent (unless they are so advanced that you are
completely unable to see) because although they affect your vision, cataracts
do not typically cause damage to the eye.
Key-Whitman provides several options to cataract patients for lens replacement
than the standard monofocal lens, which corrects vision at a single distance.
Multifocal and Accommodating lenses will correct vision at a variety of
distances and may even reduce or eliminate the need to wear reading glasses
following surgery. Cataract treatment options available at Key-Whitman include:
Crystalens®: An intraocular, accommodating lens implant that is used to improve vision
near and far away. Individuals who undergo Crystalens® laser eye surgery
can eliminate their dependence on contact lenses, bifocals and reading
glasses. Crystalens® is the most advanced form of intraocular lens
implant cataract surgery. It is also the only naturally focusing lens
available to correct vision at multiple focus distances.
TECNIS® Multifocal Lens: An implantable lens used to correct near and far vision and may also
reduce or eliminate your need for reading glasses due to presbyopia. Ninety-four
percent of patients say they would choose TECNIS Multifocal lenses again.
AcrySof® IQ ReSTOR®: An intraocular lens (IOL) that is the latest advancement in cataract
surgery technology. The AcrySof® IQ ReSTOR® IOL is designed to
provide enhanced image quality and a wide range of vision, giving cataract
patients a great opportunity to live life less dependent on glasses.
AcrySof® IQ Toric: Implantable lenses designed specifically for cataract patients with astigmatism.
If you have astigmatism, you may still experience blurred and distorted
vision with a monofocal intraocular lens, but the AcrySof® IQ Toric
lens will be better able to restore your vision by addressing the astigmatism as well.
