LASIK with Intralase
The overwhelming number of refractive laser procedures
that I do is LASIK. The reasons for this are its astonishing lack
of pain, quick return of excellent vision, and the convenience
of performing the procedure on both eyes on the same day. LASIK
is also suitable for the more extreme cases of myopia correction,
which are not appropriate for PRK.
During LASIK, I first create a thin corneal flap
using the femto-second laser by Intralase. We call this procedure Intralasik. The excimer laser is then applied
to reshape the underlying cornea. The corneal flap is replaced
upon the corneal bed that was just lasered, which is its original
position. The laser used is identical to PRK. (See description
of laser in PRK section) The flap adheres because of molecular
adhesive forces and a natural pump within the cornea that is constantly
dehydrating it so as to keep it clear. This lack of sutures allows
for very rapid visual recovery.
Considering the current advances in laser vision technology, I have been particularly impressed with the INTRALASIK technique which utilizes the femtosecond laser. Since January, 2003, I have converted to the use of this extraordinary technology 100 percent for Lasik. While I believe that the LASIK procedure is an excellent one, the creation of precise corneal flaps, the first step in preparing the eye for LASIK, is now safer and more precise with the INTRALASE FS (femtosecond laser). This technology replaces the use of the mechanical metal blade (microkeratome) traditionally used in LASIK surgery. The all-laser approach offers surgeons a computer-controlled minimally invasive technique that safely and reliably creates very precise flaps using a silent beam of light rather than a blade. A flap created with the Intralase FS laser has a uniform thickness, greater stability, and is more securely repositioned on the cornea due to the unique beveled architecture of the resection. This feature reduces the risk of flap displacement, which can cause visual aberrations and it also minimizes any damage to surrounding corneal tissue. The suction ring used with the Intralase FS laser creates a reduced intraocular pressure which also improves the safety of the procedure.
Most people see well enough to work and drive
the next day. Because the lasering occurs under the flap, there
is minimal abrasion to the corneal surface, therefore, minimizing
pain.
In addition to this summary, we are including our Intralase Fact Sheet and Informational Video, which we give to all Lasik candidates to improve their understanding of the surgery.
INTRALASE THE TOTAL LASER APPROACH

|
|
|
Step 1: The IntraLase laser is focused to a precise depth within the cornea.
|
Step 2: Corneal tissue is separated by over a million tiny, two-micron sized bubbles.

|
|
Step 3: The flap is lifted to allow for the VISX STAR S4 laser treatment.
|
Step 4: The flap is placed back into its original position after treatment.
