Before Lasik Eye Surgery
If you decide to go ahead with LASIK surgery, you will need an initial
or baseline evaluation by your eye doctor to determine if you are
a good candidate. This is what you need to know to prepare for the
exam and what you should expect:
If you wear contact lenses, it is a good idea to stop wearing them
before your baseline evaluation and switch to wearing your glasses
full-time. Contact lenses change the shape of your cornea for up
to several weeks after you have stopped using them depending on
the type of contact lenses you wear. Not leaving your contact lenses
out long enough for your cornea to assume its natural shape before
surgery can have negative consequences. These consequences include
inaccurate measurements and a poor surgical plan, resulting in poor
vision after surgery. These measurements, which determine how much
corneal tissue to remove, may need to be repeated at least a week
after your initial evaluation and before surgery to make sure they
have not changed, especially if you wear RGP or hard lenses. If
you wear:
soft contact lenses, you should stop wearing them for 2 weeks before
your initial evaluation.
toric soft lenses or rigid gas permeable (RGP) lenses, you should
stop wearing them for at least 3 weeks before your initial evaluation.
hard lenses, you should stop wearing them for at least 4 weeks before
your initial evaluation.
You should tell your doctor:
about your past and present medical and eye conditions
about all the medications you are taking, including over-the-counter
medications and any medications you may be allergic to
Your doctor should perform a thorough eye exam and discuss:
whether you are a good candidate
what the risks, benefits, and alternatives of the surgery are
what you should expect before, during, and after surgery
what your responsibilities will be before, during, and after surgery
You should have the opportunity to ask your doctor questions during
this discussion. Give yourself plenty of time to think about the
risk/benefit discussion, to review any informational literature
provided by your doctor, and to have any additional questions answered
by your doctor before deciding to go through with surgery and before
signing the informed consent form.
You should not feel pressured by your doctor, family, friends,
or anyone else to make a decision about having surgery. Carefully
consider the pros and cons.
The day before surgery, you should stop using:
creams
lotions
makeup
perfumes
These products as well as debris along the eyelashes may increase
the risk of infection during and after surgery. Your doctor may
ask you to scrub your eyelashes for a period of time before surgery
to get rid of residues and debris along the lashes.
Also before surgery, arrange for transportation to and from your
surgery and your first follow-up visit. On the day of surgery, your
doctor may give you some medicine to make you relax. Because this
medicine impairs your ability to drive and because your vision may
be blurry, even if you don't drive make sure someone can bring you
home after surgery.
During Lasik Eye Surgery
The surgery should take less than 30 minutes. You will lie on your
back in a reclining chair in an exam room containing the laser system.
The laser system includes a large machine with a microscope attached
to it and a computer screen.
A numbing drop will be placed in your eye, the area around your
eye will be cleaned, and an instrument called a lid speculum will
be used to hold your eyelids open. A ring will be placed on your
eye and very high pressures will be applied to create suction to
the cornea. Your vision will dim while the suction ring is on and
you may feel the pressure and experience some discomfort during
this part of the procedure. The microkeratome, a cutting instrument,
is attached to the suction ring. Your doctor will use the blade
of the microkeratome to cut a flap in your cornea.
The laser will be positioned over your eye and you will be asked
to stare at a light. This is not the laser used to remove tissue
from the cornea. This light is to help you keep your eye fixed on
one spot once the laser comes on. NOTE: If you cannot stare at a
fixed object for at least 60 seconds, you may not be a good candidate
for this surgery.
After Lasik Eye Surgery
Immediately after the procedure, your eye may burn, itch, or feel
like there is something in it. You may experience some discomfort,
or in some cases, mild pain and your doctor may suggest you take
a mild pain reliever. Both your eyes may tear or water. Your vision
will probably be hazy or blurry. You will instinctively want to
rub your eye, but don't! Rubbing your eye could dislodge the flap,
requiring further treatment. In addition, you may experience sensitivity
to light, glare, starbursts or haloes around lights, or the whites
of your eye may look red or bloodshot. These symptoms should improve
considerably within the first few days after surgery. You should
plan on taking a few days off from work until these symptoms subside.
You should contact your doctor immediately and not wait for your
scheduled visit, if you experience severe pain, or if your vision
or other symptoms get worse instead of better.
You should see your doctor within the first 24 to 48 hours after
surgery and at regular intervals after that for at least the first
six months. At the first postoperative visit, your doctor will remove
the eye shield, test your vision, and examine your eye. Your doctor
may give you one or more types of eye drops to take at home to help
prevent infection and/or inflammation. You may also be advised to
use artificial tears to help lubricate the eye. Do not resume wearing
a contact lens in the operated eye, even if your vision is blurry.
You should wait one to three days following surgery before beginning
any non-contact sports, depending on the amount of activity required,
how you feel, and your doctor's instructions.
To help prevent infection, you may need to wait for up to two weeks
after surgery or until your doctor advises you otherwise before
using lotions, creams, or make-up around the eye. Your doctor may
advise you to continue scrubbing your eyelashes for a period of
time after surgery. You should also avoid swimming and using hot
tubs or whirlpools for 1-2 months.
Strenuous contact sports such as boxing, football, karate, etc.
should not be attempted for at least four weeks after surgery. It
is important to protect your eyes from anything that might get in
them and from being hit or bumped.
During the first few months after surgery, your vision may fluctuate.
It may take up to three to six months for your vision to stabilize
after surgery.
Glare, haloes, difficulty driving at night, and other visual symptoms
may also persist during this stabilization period. If further correction
or enhancement is necessary, you should wait until your eye measurements
are consistent for two consecutive visits at least 3 months apart
before re-operation.
It is important to realize that although distance vision may improve
after re-operation, it is unlikely that other visual symptoms such
as glare or haloes will improve.
It is also important to note that no laser company has presented
enough evidence for the FDA to make conclusions about the safety
or effectiveness of enhancement surgery.
Contact your eye doctor immediately, if you develop any new, unusual
or worsening symptoms at any point after surgery. Such symptoms
could signal a problem that, if not treated early enough, may lead
to a loss of vision.
