LASIK
and The Options For Presbyopia
Many medical conditions are associated with aging.
Just as your bones and joints show wear and tear or aging signs
as you start to age, so will your eyes. Presbyopia is one of the
most common aging-related problems that affect the eyes. The word
Presbyopia literally translates to “old person” in
Greek. The condition is characterized by the eye’s inability
to focus on both near and far objects.
Speculators and theorists alike suggest many causes of Presbyopia,
yet no certain explanation can explain the condition’s cause.
Research however not so long ago indicated that the condition
Presbyopia may be caused from a loss of elasticity in the crystalline
lens while other experts think it is actually changes in the curvature
of the lens from continued growth and loss of strength in the
Ciliary muscles, which the weakness hinders the eye’s ability
to help the lens to hold its shape.
Naturally, aging causes various eye conditions to develop for
many people. Some people believe that those who are at risk of
Presbyopia do not have preventive tactics they can use to slow
or stop the aging disease. This is not true. (Learn about exercise
and healthy eating to reduce risks of all diseases)
LASIK comes with risks and benefits and any patient should learn
about these benefits and risks before going to surgery. Some of
the patients (With hidden symptoms of Presbyopia) who have had
LASIK surgery had experienced vision problems to the point their
vision began to deteriorate.
While there is no sure cure for Presbyopia, doctors will use standard
eye corrective treatment to help correct the eye problems. Eyewear
is commonly used, which doctors will recommend reading glasses
for those with mild cases of Presbyopia, and will recommend bifocals
or progressive lens for those with more serious case of Presbyopia.
Reading glasses are used as sort of magnifying glasses to help
a person read smaller print. Progressive lens and bifocals are
used to treat certain Presbyopia conditions, which the doctor
must provide two different prescriptions. One of the prescriptions
is used to treat nearsightedness while the other prescription
treats farsightedness. The doctor will clearly separate the prescriptions
for bifocal lens, while the progressive lens are prescribed and
tend to blend with the other.
Thanks to advances in eyewear, people with Presbyopia can also
choose three types of contacts. Now patients have a choice of
monovision contact lenses, bifocal contact lenses, and multifocal
contact lenses. Monovision lenses, as their name suggests, targets
one eye at a time. In other words, the dominant eye lens is adjusted
so the patient can see at greater distance while the non-dominant
eye lens is used for near or close vision.
Initially, patients who are prescribed monovision lens may find
it difficult at first to wear the lens. In many instances doctors
will need to adjust the lens to fit the patient’s needs.
The eyes and the brain must also adjust to the lens however.
Bifocal contact lenses work in a similar ways to bifocal glasses.
The doctor will give the patient two different prescriptions.
Two different prescriptions are also given to patients who are
prescribed multifocal lens. The lens gives the eye the ability
to see at multiple focus points while viewing near or far objects.
LASIK surgery has provided great results for millions of patients.
As the procedure improves or advances, there are now methods available
for patients with conditions like myopia, hyperopia, and astigmatism.
Unfortunately, traditional LASIK is still not a good option for
patients diagnosed with Presbyopia.
What puts a Presbyopia patient at risk of LASIK is the fact that
because the symptoms are often hidden, doctors usually do not
diagnose the patient in time. This means the patient may seek
corrective eye care from LASIK and not even know they have Presbyopia.
Because of the commonness of the disorder, much research is being
done on Presbyopia, and surgeons are looking for alternative treatments.
Some options are already available. Today, some surgeons are combining
Conductive Keratoplasty and LASIK Monovision to correct near and
distant vision problems in two separate operations. Doctors also
consider Presbyopia Reversal with Sclera Expansion bands, Laser
Presbyopia Reversal, and Anterior Ciliary Sclerotomy to correct
eye problems. Surgeries such as Crystalens, ReZoom Multifocal
Intraocular Lenses, and ReSTOR intraocular lenses replace LASIK
surgery and are often used to enhance the eye’s lens by
using Crystalens.
At this time there is no known LASIK procedure capable of repairing
damaged caused from Presbyopia. Sciences however are working hard
each day to find other alternatives for Presbyopia patients.
