eye drops, to be used for the treatment
of cataract, require 2 drops into each eye,
twice daily for a period of 6-12 months
(although due to the nature of senile cataract
a permanent continuance may be advisable).
Clinical trials indicate
an eye condition improvement of 41.5% to
100% for patients within a 6-month period
with sustainable results 24-months later.
Another study on 96 patients
aged 60 years old having senile cataract
of various degrees of maturity, with the
duration of the disease from 2 to 21 years,
showed that carnosine gives a profound effect
on primary senile cataract, the effective
rate being 100%.
For mature senile cataract,
the effect rate is 80%, and positive effects
were observed with other types of cataract.
The findings from a recent
report say "A need exists for development
of therapeutic agents to slow age-related
loss of antioxidant's in the nucleus of
the human lens to delay the onset of cataract".
Free radicals for the most part cause cataracts
and other senile eye disorders. Oxidative
stress is also a contributing factor in
the development of macular degeneration.
Degenerative changes in
the eye often begin in middle age, resulting
in macular degeneration, glaucoma, cataracts
and other forms of retinopathy in later
life.
"Already, after just
seven weeks of using them the white film
has cleared from her eyes and there is now
just a very small patch left in the corners.
She can now see my finger again which she
couldn't before and everyday like clockwork
she reminds me that it's time for her drops."

Phacoemulsification,
or phaco. Your doctor makes a small incision
on the side of the cornea, the clear, dome-shaped
surface that covers the front of the eye.
The doctor then inserts a tiny probe into
the eye. This device emits ultrasound waves
that soften and break up the cloudy centre
of the lens so it can be removed by suction.
Most cataract surgery today is done by phaco,
which is also called small incision cataract
surgery.
Extracapsular surgery.
Your doctor makes a slightly longer incision
on the side of the cornea and removes the
hard center of the lens. The remainder of
the lens is then removed by suction.
In most cataract surgeries,
the removed lens is replaced by an intraocular
lens (IOL). An IOL is a clear, artificial
lens that requires no care and becomes a
permanent part of your eye. With an IOL,
you'll have improved vision because light
will be able to pass through it to the retina.
Also, you won't feel or see the new lens.
Sometimes a part of the
natural lens that is not removed during
cataract surgery becomes cloudy and may
blur your vision. This is called an after-cataract.
An after-cataract can develop months or
years later.
When our eyes are young
they contain high concentrations of natural
antioxidants that protect against cataract,
macular degeneration and other ocular disorders.
As we enter middle age,
synthesis of the antioxidant glutathione
is reduced, resulting in excessive free
radical damage. Antioxidant supplements
(Ethos lan vital) have been shown to help protect
against senile eye disorders but unfortunately,
aging diminishes circulation to the eye,
thereby reducing the effectiveness of oral
supplements.
