Astigmatism is a common visual disorder which can happen by itself
or with nearsightedness or farsightedness. It decreases the visual
quality for both near and distant ranges. Visual distortion caused
by low degree of astigmatism can be treated with glasses special
contact lenses. However, high degree of astigmatism can be
effectively corrected through laser eye surgery such as Astigmatism
Lasik. Surgeries related to astigmatism are much more complex
because it has both magnitude and orientation. People with
astigmatism have vague vision of varying degrees..
Astigmatism is corrected through Lasik by flattening the steeper
curve of the cornea. This helps to decrease the cornea’s four-sided
shape and creates a more circular form. During the surgery, laser
pulses are accurately delivered to corneal tissue in the axis of the
steeper curve. By contributing to the overall globular shape of the
cornea, Astigmatism Lasik surgery enables the eye to focus light
rays more competently, resulting in clearer, crispier vision.
Astigmatism caused by wound dehiscence after cataract extraction,
can also be corrected through astigmatic keratotomy or LASIK.
Astigmatism Lasik openings, unless extremely short or long,
typically are neutral with respect to the spherical equivalent.
Newer laser software is now able to correct hyperopic astigmatism by
steepening the flat axis. Although an ideal goal of Astigmatism
Lasik is to correct all of the astigmatism, a more realistic goal is
to make the use of contact lenses or glasses comfortably.
Best candidate for Astigmatism Lasik:
• A person should be atleast 18 years of age for Lasik surgery to
correct astigmatism.
• Pregnant or nursing women are not eligible for LASIK to correct
astigmatism.
• Certain prescriptions do not allow considering Astigmatism Lasik.
• You need to be in good health before having Astigmatism Lasik.
• Your eyes also should be healthy if you are planning to have
Astigmatism Lasik.
Benefits:
Most important benefit of Astigmatism Lasik is that it is the only
treatment available for astigmatism that actually concentrates on
the source of the problem rather than simply treating the symptoms.
Risks Involved:
There are many risks involved in Astigmatism Lasik as there is
always a chance of complications.
• Astigmatism Lasik is not reversible.
• Since the procedure is still new, the long-term negative effects
of LASIK to correct astigmatism are not known.
• Your vision may not be perfect even after the surgery.
• When you have LASIK to correct astigmatism you may need additional
surgery.
• Astigmatism Lasik is often not covered by insurance companies.
• You will still need reading glasses at some point in your life,
usually after forties.
Hence, you need to be sure to find a surgeon who is experienced in
performing Astigmatism Lasik. Find out the success rate of the
surgeon who plans to do the LASIK to correct astigmatism. Make sure
the laser is approved by the FDA. It is always better to have a
general knowledge of the procedure and the risks involved before the
surgery.
