Are you over 50 and using spectacles to
read this article? Do you hate your reading glasses? If so, keep
them on and keep reading, help may be at hand!
Unfortunately, the need for reading glasses is a natural progression
of aging. The first signs are the fact that you have to hold this
magazine further away to be able to read it, and you also find that
you need a good light to be able to see the words clearly.
Eventually you run out of arms, and you succumb and buy reading
glasses. This means that you have become a slave to your spectacles.
Like the Amex card, at your own risk, never leave home without them!
Eventually you keep one pair at home, another in the car and another
in the office. And your nose gets funny indentations either side of
the bridge, where the spectacles settle.
It is important that you understand just why this happens. As you
get older, all the ‘elastic’ tissues in your body become less
pliable. Knees, lower back, fingers, neck, the list is endless.
However, you have to add to that list, the lens in your eye.
The fiddly little lens, supplied at birth as a standard feature,
does not have a fixed focus, but under your control you can make it
focus close up (to read) and then also focus at a distance, such as
when you are following your golf ball as it slices into the water
hazard. The way you do this is by ‘bending’ the lens to be able to
focus on near objects. Unfortunately, as the lens becomes less
pliable, the muscles in your eye become unable to bend the
stiffening lens enough to produce the near point focus. The near
point moves further away, until you have run out of arms, as
described previously. We medico’s call this condition ‘Presbyopia’.
Unfortunately there is yet another result of aging that occurs in
the lens of the eye.
This is a gradual cloudiness which lowers the visual acuity, slowly
lowers your ability to see colours, and eventually brings on
blindness. So not only can you not see well enough to read the
magazines, but you also begin to lose your distance vision. Welcome
to the wonderful world of white sticks and woofing Labrador dogs. If
you think this is an exaggeration, currently between 12 and 15
million people are estimated to be blind from cataracts, according
to the World Health Organization, and by the year 2020, this will be
54 million people.
The initial method of treating this was by removal of the now
optically inefficient natural lens, and attempting to return some
usable vision through the introduction of very thick and heavy
spectacles placed before the eye. These glasses looked as if the
lenses were made from the bottom of Coca-Cola bottles (registered
trade mark and all)and were just as heavy. The patient could see
again, but reading required even thicker lenses, or hand-held
magnifying glasses. Not all that comfortable, but beat the
alternative.
However, in 1949, a Dr. Harold Ridley noticed that pieces of
shattered Perspex after a penetrating eye injury in aircraft crashes
did not produce a reaction within the eye.
This was the first step towards production of the Intra-Ocular
lenses (now referred to as IOL’s as we medico’s love acronyms). It
became possible for us to replace the cloudy hard lens with a clear
lens. This too was a hard lens, but optically clear. The patients
could see again, but did need reading glasses, as the lens had a
fixed focus.
So we come to the latest development in IOL’s. The focusable lens,
under the control of the patient’s own intra-ocular (ciliary)
muscles. With these lenses you can read your golf scorecard with
your near vision, focus on the ball on the tee with your
intermediate vision and then using your distance vision watch it
gently arcing into the water hazard. (These new IOL’s can improve
your sight, but not your golf, I am afraid.)
One of the leaders in this field is the German Akkommodative ICU
lens which represents the latest development in artificial lenses
and can provide patients with a better quality of life. This is a
lens which is designed to change shape, providing similar functions
to a natural healthy lens. These IOL’s meet all the European
requirements for implantable medical devices.
We also have Dr. Somchai Trakoolshokesatian who practices at the
Bangkok Pattaya Hospital, who is one of the world leaders in
inserting these new lenses. His figures after two years of using
these IOL’s show a patient satisfaction level after surgery of 94
percent. In addition, 95 percent said they would have the surgery
again if it were necessary. 94 percent no longer needed reading
glasses, and 97 percent did not need glasses for distance vision. In
medicine, we can never give 100 percent guarantees, but 94 percent
represents not bad odds, in anyone’s language.
The results have been so outstanding, that medical ‘tours’ are
coming to this country to have this operation. Word of mouth and 94
percent satisfaction rates, have been bringing people to Thailand
for the operation that can return their sight to what it was when
they were 20 years old.
In the words of Dr. Somchai, “SuperSight Surgery is exciting, but it
isn’t for everyone. We would like to assure that everyone undergoing
a procedure has healthy eyes. However (generally speaking) anyone
who is farsighted and unable to see up close, or is now beginning to
notice their vision isn’t as good as before, will probably be a good
candidate for SuperSight Surgery.”
SuperSight Surgery works best in what are technically known as
hyeropic presbyopes, meaning those individuals who are farsighted
and have lost the optimal close up focusing ability of their eye’s
natural lens. Presbyopes typically wear glasses for close-up work or
reading, however because each individual’s situation is different, a
consultation with Dr. Somchai is the only way to definitely
determine if you are a good candidate for the procedure.
Dr. Somchai again, “We can’t offer guarantees. While SuperSight
Surgery does not promise perfect vision, it does hold the promise of
reducing one’s dependence on contact lenses or glasses. However,
after your initial consultation, we will be able to give you a clear
indication as to what you should expect and the likelihood of your
achieving it.”
So what does it cost? The current fees for the procedure are USD
4,500 or 3,600 Euro, which include surgery fees, the special lenses,
implantation for both eyes and medicines on the day of surgery and
one night stay in hospital. |
