When interested and potential patients inquire about
refractive eye surgery, they ask: How does laser eye surgery work? How does
LASIK work? For LASIK has become synonymous with laser eye surgery.
Some facts about LASIK are needed before one can get to the
answers of: how does laser eye surgery work?
LASIK stands for Laser In-situ Keratomileusis and FDA has approved this
surgical technique since 1998. Eye surgeons normally prescribe this laser eye
surgery procedure for persons who have nearsightedness, farsightedness and
astigmatism and who have thick corneas.
The preliminary step begins with the eye surgeon administering tests to check
your suitability for LASIK. If you have dry eye syndrome, diseases like
glaucoma, cataract or diabetes, you will be strongly advised not to undergo the
treatment. Reputable clinics report that at least 50% of those who come in for
an initial consultation are rejected.
So how does LASIK? How does laser eye surgery work?
First phase of the operation
To begin, you are positioned on a reclined chair, and a numbing drop of
solution placed in your eye. Afterwards the cornea is cleaned of floating
foreign matter, and then instrument called a lid speculum is put over your eyes
to keep the eyelids open. The ring is place right on the eyeball. Suction is
then applied around your cornea. You’ll experience blurring and dimming of your
vision. Then the surgeon uses a microkeratome (surgical knife) to create a thin,
circular flap in the cornea.
Second phase
Afterwards, the microkeratome and ring are removed. The doctor then asks you
to stare at the light. This is to get your eye stay focused on a fixed object,
so that the doctor can proceed to the final phase of the operation.
Third phase
The pre-programmed laser then cuts corneal tissue, thereby reshaping it.
After the cornea has been reshaped, the flap is replaced back with a
preventative shield is placed over your eyes to protect them from irritants.
The actual operation would have taken you less than a minute, with improved
vision apparent in 24 hours.
Post operative care is as important as the operation itself. So don’t drive
for a few weeks. Don’t do contact sports. Go for the post operative check ups
the eye surgeon has scheduled with you.
Follow the do's and don'ts faithfully, so you'll be able to answer the
question: How does a safe laser eye surgery work? With a bright smile and clear
vision.
