Next, a soft, flexible synthetic intraocular lens (IOL) is
inserted into the lens capsule of the eye. There is also a multi-focal lens
option to provide distant, near and intermediate vision.
In most cases, the incision is so small that the eye heals
rapidly with little or no discomfort. Drops are used after cataract surgery,
and the patient is asked to refrain from swimming or water activity for two
weeks.
Cataracts are an opacity or clouding of the normally crystalline lens of the
eye, caused by the natural aging process, metabolic changes, injury, various
forms of radiation, toxic chemicals and certain drugs. The leading cause of
vision loss among adults age 60 or older, cataracts impair vision, making
everyday activities increasingly difficult.
In simple terms, a cataract is usually part of the normal aging process that
changes the natural, clear lens of the eye into a cloudy, opaque structure that
inhibits or diminishes the passage of light to the retina. The condition can be
compared to a window that is frosted or "fogged" with steam.
Symptoms:
Patients with cataracts often experience the following symptoms:
* Blurring of vision.
* Glare, or sensitivity to light.
* Double vision in one eye.
* Frequent changes in eyeglass prescription.
* Difficulty in reading in low light.
* Declining night vision.
* Fading or yellowing of colors.
Detection:
Adults over the age of 40 should schedule routine eye examinations on an
annual basis to determine whether cataracts or other eye disorders are
present. A thorough examination by an ophthalmologist or qualified eye care
professional usually includes:
* A visual acuity test to measure clarity at various distances.
* Pupil dilation to examine the lens and retina for other eye problems.
* Tonometry, a standard procedure to measure fluid pressure inside the eye.
Safe Surgery; Speedy Recovery:
Not long ago, cataract surgery required a hospital stay and was usually
postponed as long as possible. Today, the procedure is performed on an
out-patient basis and takes only a few minutes. Patients are free to return
home to rest in comfort and avoid the inconvenience and expense of a hospital
stay. In most cases, daily activities such as driving and reading can be
resumed almost immediately.
During the surgery, the cloudy lens is removed from the eye. In
most cases, the focusing power of the natural lens is restored by replacing it
with a permanent intraocular lens implant.
Cataract surgery is considered one of the most popular and
highly successful procedures, with improved vision occurring in over 90 percent
of cases. In fact, a study by the American Society of Cataract and Refractive
Surgery
recently reported that more than 98 percent of cataract patients had their
vision successfully improved following surgery. Many patients report vision
that is even better than before they developed cataracts. Results are
permanent; once removed, cataracts will not reoccur.
