CATARACTS & CATARACT SURGERY
INTRAOCULAR LENSES TO CORRECT
DISTANCE & NEAR VISION
WITHOUT THE NEED OF GLASSES
Dr. Howell has been performing
cataract surgery in Amarillo since 1964. In the 70's he
became proficient in the additional insertion of
intraocular lenses (IOL's) after the cataract was
removed. The use of IOL's revolutionized cataract
surgery. This eliminated the need for the thick cataract
glasses which were necessary to correct the vision after
removal of cataracts in most older patients. This new
technique allowed the patient to have the same or better
vision than they had before cataracts developed. Dr
Howell is a charter member of the American Society for
Cataract & Refractive Surgery which pioneered the use of
IOL's in America.
Since September 2005 a new multifocal intraocular lens (IOL) was
introduced which is able to correct the vision for distance & reading
alone, with no glasses or contact lens necessary. This is called the
Acrysof ReSTOR IOL. There is correction for distance & near in the same
IOL. In the pre- market studies 80% of the recipients who had both eyes
operated did not wear glasses at all for vision, neither distance nor
near. Of those who remained 15% wore them some of the time & 5% wore them
much of the time. Certain conditions must be met to be a candidate for
this IOL which will be discovered in the examination prior to surgery. One
must be prepared to have both eyes operated the same way to obtain the
best results. The IOL itself is much more expensive than the monofocal IOL
which is generally used & Medicare will not & private insurance may not
pay the difference. In those situations, it will be the responsibility of
the patient to pay that difference. Preparation for the surgery by the
doctor & staff is more complicated for this type surgery which Medicare
will not & insurance may not pay. Again this additional expense will be
the responsibility of the patient. There is no more risk in the surgery
itself than regular cataract surgery but more measurements & decisions
must be performed. To be as accurate as possible, these measurements must be
repeated at least twice & this can
be time consuming.
If one is not interested in multifocal IOL's but wants good distance or
near vision or to correct the distance in one eye & near in the other
(monovision) & this is very important to that individual, extra care can
be taken to insure this. This may require performing extra surgery
at the time of the cataract surgery to reduce or eliminate astigmatism.
It will certainly require repeating several of the measurements at least
twice & taking more time evaluating this information. Again Medicare
will not pay for the extra time taken & would be the responsibility of the
patient. The cost of the IOL would be paid by Medicare however.
Dr. Howell has performed thousands of
cataract extractions, most with IOL insertion & is very
competent in this surgery. Since 1990 (when these
statistics were started), 96% of the patients operated
on by Dr Howell have had a good visual result from
cataract surgery. Of the 4% that did not, 3/4 of that 4%
had some potential problem before surgery that turned
out to be what prevented good vision post operatively.
Therefore only 1% of the operated patients had an
operative problem which prevented the vision from being
good.
Patients frequently ask when they
need cataract surgery. The answer; surgery is indicated
when the patient can no longer see to do the things that
they enjoy doing. If reading the print on the TV screen
or street signs is difficult, that is a good reason for
surgery. When reading the newspaper or magazines is a
chore, surgery is indicated. Surgery is indicated when
one can no longer follow the flight of their golf ball
or not see down the barrel of their shotgun to enjoy
hunting. Many older persons stop doing the things they
enjoy because of poor vision rather than questioning why
that is necessary. Older patients in poor physical
health frequently can only enjoy the things they can see
to do.
Age is seldom a reason for not having
surgery. Cataract surgery today is about like going to a
dentist's office & having a tooth pulled. It is not
something to look forward to; however, it is not a
terrible experience, Many of our patients tell us that
they did not have one pain during the entire process. In
most instances, normal activities can be resumed only a
few days after surgery.
If you, a friend, or someone you love
is having difficulty seeing to do the things that are
enjoyable, call 358 7558 or 800- 658- 6462 & make an
appointment for an examination at Amarillo Eye Care
Center. Most health insurance & always Medicare pays the
major portion of the bill. We are happy to file any
insurance or Medicare forms for our patients.
The following are our pre- &
post-operative instructions to our patients including
instructions about post-operative activities.

When you
run out of this medication switch to the Vexol drops in the case

no more.
- Your vision may or may not be very good.
If it is not, do not be alarmed about your vision. It is too soon

in for an additional examination.
POST OPERATIVE ACTIVITY INSTRUCTIONS
DO NOT RUB YOUR
OPERATED EYE. DO NOT BUMP OR HIT YOUR OPERATED EYE. DO
NOT SQUEEZE YOUR EYES CLOSED TIGHTLY.
You should have
something for protection in front of your eye at all times, either glasses
or the protective shield. When you go outside during the daylight
time, you must wear the special dark glasses that are provided.
You may perform any
activity you wish if you follow the instructions above. Bending over
or performing heavy
physical activity will not damage your eye; however excessive
reading, watching TV, or any physical activity may cause discomfort in
your eye for the first few days after your surgery. This is NOT
causing any damage to your eye. It is normal because of the recent
surgery. After a few days, the pain will not be a problem.
Bending over or
picking up heavy objects will not harm your eye. It is permissible
to sleep with your head turned to the operated eye if you do not press
your eye into the pillow. It is not necessary to sleep on more than
one pillow.
If you wish to have
your hair done at the beauty salon, wear the protective shield over your
eye while there. You may go anytime you wish after surgery.
DO NOT RUB YOU
OPERATED EYE. DO NOT BUMP OR HIT YOUR OPERATED EYE. DO NOT
SQUEEZE YOU EYES CLOSED TIGHTLY.
