Restasis is the most widely
prescribed eye drop used for the treatment for dry eyes.
Unlike artificial tears which lubricate the eye, Restasis
works by facilitating the production of tears. Bottom line:
Restasis treats the cause of the dry eye rather than the
symptoms of dry eye.
As
a part of normal degenerative processes of aging, the
tear production glands in the eyelids and on the surface
of the eye become inflamed and lose their ability to produce
oil, water and mucous. If this inflammatory process is
allowed to progress, these cells ultimately die and lose
their ability to produce the lubricants so vital to the
health and comfort of the eye. Certain ocular conditions
like chronic blepharitis and conjunctivitis and certain
medical conditions like autoimmune diseases all tend to
be inflammatory in nature and further accelerate the more
subtle inflammatory processes of aging.
Restasis is an immuno-suppressive agent and works to relieve
dry eyes by virtue of its anti-inflammatory properties.
Chronic inflammation of the oil producing tear glands results
in diminished oil and mucous production. Ultimately this
process can progress to essentially no tear production what-so-ever.
Reduced tear production results in extremely uncomfortable
and unhealthy eyes. Simply speaking, chronic inflammation
damages the tear producing glands and prevents them from
functioning. Restasis, by suppressing the inflammation in
the tear glands at the molecular level, allows the tear
producing cells to return to normal and start producing “good
tears” again.
All good things come with time:
Because it takes a while for this entire process to work,
relief from Restasis is not a “quick-fix”.
It takes about 3 to 4 months to significantly alter the
tear production process. Consequently it takes that long
to really observe and feel the effects of Restasis. For
this reason, the eye doctor generally will see the patient
at one-month intervals during the start-up period in order
to assess the physical signs of improvement that generally
precede the symptomatic relief that the patient is waiting
for. Because it takes so long to work, these visits often
provide a “up-lift’ to the patients who very
quickly can become discouraged and disheartened by their
dry eye symptoms.
What the doctor sees:
The eye doctor can actually observe the effects of dry eyes
on the surface of the cornea. By using a yellow anesthetic
dye, the doctor is able to assess and measure the degree
of dryness. The doctor sees this dryness as superficial
punctuate staining (SPK) on the cornea. This actually
represents areas where the normal cells have died and
literally fallen off. It is analogous to chapped skin,
but on the front of the eye (conjunctiva and cornea).
And just as chapped skin is uncomfortable, dry eyes (chapped
skin of the cornea) can be miserable.
What the patient feels:
Once the surface protective cells have fallen off the cornea
and the nerves are exposed, the patient experiences symptoms
of grittiness, a sandy feeling, itching, burning, redness
and fatigue. It often feels like something has fallen
into the eye and is moving around. This sensation occurs
because your upper lid is actually rubbing against the
exposed nerves of the cornea. Often the patient complains
that there is something in the eye and that it is moving
around. This occurs because it is your eye that is moving
relative to the eye lid. As you look up-and-down or left-and-right
the eye lid keeps rubbing against the exposed nerves from
a different direction. Tear film dysfunction is generally
referred to by the symptom it creates, “dry eye”.
The tear film not only cleanses, moistens, feeds and protects
the eye, but it also has the greatest effect on the light/images
that pass through it for focusing as compared to any other
part of the eye. Dysfunction of any part of the tear film
can thus cause infection, pain and discomfort and can
compromise daily activity and quality of life, including
decreased vision. Just as a dirty automobile windshield
greatly reduces clarity and causes glare, so too a dry
cornea can cause blurry vision and glare.Can dry eye symptoms
be cured?The short answer is, No! Like any condition of
aging, dry eyes can be controlled, but not cured. Restasis
along with other dry eye treatments can keep a patient
feeling healthy and normal.
What else can I do for dry eyes:
There are a number of effective treatments for the symptomatic
relief of dry eyes both systemic and topical. Nutritional
oil supplements and artificial tears are the mainstay
of dry eye treatment.

It has become apparent
that omega fatty acids are exerting
an anti-inflammatory effect upon the tear glands. |

Nutritional
Supplements:
Fish Oil - Flaxseed Oil – Borage = Omega 3-6-9 The
benefits of omega fatty acids as nutritional supplements
have been touted for many years as being good for your heart
and overall wellbeing. Their use in dry eye was initially
thought to be related to the lubricating benefits of these
natural oils. Most recently, it has become apparent that
they are also exerting an anti-inflammatory effect upon
the tear glands as well. So, once again, as with Restasis,
the basic inflammatory abnormality causing dry eyes is being
treated. You should consult one of our doctors as to which
of these nutritional supplements would be best for you and
which may be contraindicated because of certain systemic
medications that you may be taking.
Artificial Tears:
Artificial tears work on the eye in much the same fashion
as lubricating creams work on dry skin. They are made
up of various lubricants that attempt to mimic the oil
and mucous components of your normal tear film. Depending
upon an individual patient’s deficiency (oil or
mucous) one particular artificial tear may provide better
symptomatic relief than another. Often it is a matter
of trial and error before the appropriate tear match is
made for the patient. If you are taking tears more than
3-4 times a day, you probably would benefit from Restasis
and should be evaluated. Ocular Decongestants: There are
many eye drops that work by constricting or “bleach” the
blood vessels in the conjunctiva (skin of the eye). These
are not an effective way to treat dry eyes. A lubricant
(artificial tear) is what is needed, not a decongestant.
Decongestants have a roll in the treatment of allergic
eye conditions, but are generally are not helpful in treating
dry eyes. |
