is a cataract
order for the eye to see clearly, light rays enter through the front,
clear portion of the eye known as the cornea. From here, the light
rays pass through the pupil and the lens of the eye, where they are
precisely focused on the retina. The retina is the photosensitive
membrane or "screen" at the back of the eye that transforms these
light images into electrical signals. These impulses are passed through
the optic nerve to the brain, which interprets them as images.
cataract is a progressive clouding of the normally transparent crystalline
lens of the eye that interferes with light focusing on the retina.
It is normally caused by the aging process, but can occur as a result
of trauma to the eye, drugs, systemic disease and ocular disease.
are the symptoms of a cataract ?
When a cataract first begins, people will notice a painless
blurring of vision. This can be associated with sensitivity to light
and glare, especially in bright sunlight or while driving at night.
As the cataract worsens and the cloudiness increases, more light is
blocked from getting to the retina. At this stage, many people will
complain of poor night vision, the inability to read or watch television,
and the fading and yellowing of colors.
How is a cataract detected ?
thorough eye examination by Dr. Jacobs can detect the presence and
extent of a cataract, as well as any other condition that may be causing
In addition to the cataract, there may be other reasons for visual
loss, particularly problems involving the retina or optic nerve. If
these problems are present, perfect vision may not return after cataract
are cataracts treated ?
If symptoms from a cataract are mild, a change of glasses may
be all that is needed to function more comfortably. There are no medications,
dietary supplements, exercises, or optical devices that have been
shown to prevent or cure cataracts. When you are not able to see well
enough to do the things you like to do, cataract surgery should be
considered. Surgery is the only way to remove a cataract.
to popular belief, cataracts are not removed by laser and they do
not need to be "ripe" before they can be removed.
can I expect if I decide to have surgery ?
cataract surgery involves the removal of the clouded, natural lens
of the eye and replacing it with a man-made intraocular lens implant
to restore good vision.
Jacobs performs the outpatient procedure under local anesthesia using
a "no-stitch" technique. Dr. Jacobs first removes the
cataract by using a process known as "phacoemulsification".
This advanced technique uses ultrasound to break up and liquefy the
cataract, which is then suctioned out through an extremely small
Dr. Jacobs restores the focusing power of the natural lens by replacing
it with a man-made permanent intraocular lens implant. As illustrated,
the intraocular lens implant functions just like the natural lens
of the eye to once again focus light rays clearly onto the retina.
surgery is considered one of the
most successful surgical procedures performed today with a success
rate of over 95%. More than a million people have successful cataract
surgery each year in the United States.
to expect after cataract surgery ?
Dr. Jacobs is a specialist in small incision cataract
surgery. This means patients recover faster than ever before. Since
Dr. Jacobs performs this procedure on an outpatient basis, patients
come in for their surgery in the morning and are home by that afternoon.
Dr. Jacobs sees all patients the following day at his office. Vision
usually returns within a day, and total recovery takes 2-3 weeks.
For most patients there is little, if any, disruption in their daily
