Why should I consider LASIK vision correction?
Are you dependent on glasses or contact lenses to see
clearly to drive? Does having to wear glasses or contacts
seem like a burden? Are you an active outdoors person? Would
not having to wear glasses or contacts make you feel better
about yourself? Do you sometimes wake up in the middle of
the night and stumble about without your glasses or
contacts? Would you like to have clear, unaided vision 24
hours a day? LASIK vision correction can eliminate the need
for wearing glasses or contacts.
How do I know if LASIK is right for me?
The best thing to do is to contact us for a complementary,
no obligation evaluation. At the Rahmani Eye Institute you
will be asked a series of questions that can help you
determine if LASIK might be the clear answer you're looking
How do "RK", "PRK" and 'LASIK" surgical procedures differ?
RK ("Radial Keratectomy") is a surgical operation that
uses a fine diamond blade to make cuts around the hub of the
cornea. This relieves pressure so that the center area of
the cornea flattens slightly. The flatter cornea changes the
angle and focal length of light entering the eye. RK was an
early, less exact surgical procedure that has essentially
been replaced by PRK and LASIK surgery. PRK (Photo
Refractive Keratectomy) refers to the first "Excimer laser"
procedure that was approved for use in the United States.
PRK makes no incisions and requires no sutures. PRK uses a
"cool" beam of light to remove and reshape microscopic areas
of both the inner and the outer corneal layers. LASIK (Laser
In Situ Keratomileusis) is the most advanced procedure of
laser eye surgery available today. LASIK does not reshape
the outer protective surface of the cornea (epithelium).
Instead, a "microkeratome" (a high precision surgical device
used in LASIK procedures) lifts back a microthin flap of the
tough outer cornea. The Excimer laser then reshapes only the
curvature of the inner cornea. The corneal flap can then be
safely laid back in place. It seals naturally in only a day
or two, typically without requiring any sutures. With the
LASIK process, vision correction is more accurate, healing
and recovery times are faster and more comfortable and there
is much less risk of infection than with other procedures.
Does LASIK surgery provide lasting results?
Yes. LASIK surgery creates a permanent change in the shape
of the cornea and thus a lasting correction. LASIK surgery
does not affect the inner lens of the eye. As part of the
process of natural aging the lens tends to lose some of its
flexibility. The result is a loss of fine tuned focus and a
corresponding difficulty reading small print. Reading
glasses may eventually be required after the LASIK procedure
as would be the case with the aging of the inner lens of any
Is the laser painful?
No. Anesthetic eye drops numb the eyes before the
procedure. The Excimer laser itself emits a cool beam of
light which precisely shapes the cornea in extremely brief
pulses that smooth surfaces in mere millionths of an inch at
Has laser eye surgery been around long?
Laser vision correction has been available since about
1987. In that time there have been more than two million
laser vision correction procedures performed around the
world. Approved by the FDA for use, the Excimer laser has
been recognized as exceptionally safe and effective.
Clinical trials conducted by the FDA showed 100% of patients
diagnosed with mild to moderate myopia achieved
significantly improved vision following laser vision
Are all patients who wear glasses or contacts good candidates for LASIK eye correction?
Not necessarily. LASIK produces good results for almost
every degree of myopia or 11 nearsightedness". And LASIK can
also treat mild to moderate cases of hyperopia or
"farsightedness". But vision problems due to the aging of
the lens of the eye (presbyopia) and extreme cases of
farsightedness may best be corrected by other methods which
Dr. Rahmani may discuss with you.
What kind of improvement can I look forward to with LASIK vision correction?
While it is evident that no result can be absolutely
guaranteed with any surgical process, a recent study showed
98% of patients who were treated for nearsightedness" and/or
astigmatism achieved 20/40 vision or better from laser
How long does the LASIK procedure take?
The surgery itself actually takes only a few minutes.
But including a preoperative examination and a short (20 to
30 minutes) in-off ice recovery time, you may plan on about
two to three hours from the time you arrive at the Rahmani
Eye Institute until you are ready to leave.
What will my vision be like the day after I have LASIK surgery?
Patients may see an immediate improvement in their
vision. But you will normally be able to see much more
clearly without your contacts or glasses within a day after
your LASIK surgery. Improvement of your vision usually
continues over the first week or so after your LASIK vision
Is LASIK covered by my insurance?
Ask your insurance carrier to be sure. Generally,
refractive surgeries are considered an "elective procedure".
As such they are often not covered.
Traditional LASIK is a very good procedure. While the risk
of complication is very minimal, all surgery carries some
degree of risk. Now, an advanced computer controlled laser
technology is available that significantly reduces the risk
of complications. It is known as IntraLase.
The IntaLase laser is uniquely safe, uniquely precise, and
offers patients predictably better visual results. The
advanced IntraLase technology has given many patients more
confidence when considering laser vision correction.
Surgeons frequently prescribe the INTRALASE™
FS laser because it provides micron level accuracy and
significantly reduces the possibility of risk and
How is IntraLase different from traditional LASIK?
LASIK is actually a 2 step process. First, a flap of corneal
tissue must be created and then folded back. The cornea is
the transparent dome-like structure that covers the iris and
pupil of your eye. By creating a flap in the cornea, the
surgeon is able to perform the laser vision correction
treatment on the inner layer of the cornea, which
practically eliminates any patient discomfort and allows for
a rapid visual recovery.
Traditionally, the surgeon has created the corneal flap
with a hand-held mechanical device which utilizes a surgical
blade. This method has worked well over the years; however,
the performance of these devices can be unpredictable. And
although LASIK complications are rare, this mechanical
device is frequently the source for many of the reported
With the IntraLase laser, the surgeon uses the precision of
a laser to create the corneal flap. The accuracy of the
laser (100 times more accurate than a blade) is unparalleled
by any other technology in vision correction surgery. This
advanced technology allows the surgeon more control during
the procedure, and even allows customization of the corneal
flap for every individual patient. Because of its consistent
accuracy, IntraLase now makes it possible to treat many
patients who were dismissed as candidates for laser vision
correction due to thin corneas.
