LASIK Procedure
Step 6: Your LASIK procedure
Prior to your procedure, it is very natural to feel a mixture
of eager anticipation and nervousness. Most LASIK patients describe
similar experiences, so be reassured this is both common and absolutely
normal. You will be given a mild sedation, such as Valium or Ativan,
to help you relax during your procedure (and to nap at home afterwards).
LASIK eye surgery is an ambulatory procedure, which means that
you walk into our surgery facility, have your procedure and then walk
out again. We suggest that you print out the map and directions
to take with you.
You will need to arrive 1 hour prior to your appointment time,
and be as well rested as possible. The entire process, including recovery,
will take approximately 2 hours or less. Step-by-step: - First, you will be lying on a comfortable, laser bed. Your
eyelid area will be cleaned with a disinfectant; then your eyes will
be numbed with special eye drops - no general anesthetic is necessary.
- Dr. Seibel will position your head
under the laser. A device called a lid
speculum will be placed over one eye, to gently and comfortably
hold your eyelids open - a soothing balanced salt solution is
used to keep your eye moist and comfortable.
- Your eyelashes will be draped to keep
them out of the surgical field. A lightweight suction-ring will be
placed on your eye to create a very gentle pressure (for creating the flap);
the lights may appear to go out for a brief period.
- Dr. Seibel maintains full view of your
eye through a surgical microscope to ensure ultimate precision
and guidance. He always has complete control over the laser,
being able to instantly pause it at any time.
- Using the IntraLase Laser,
Dr. Seibel will create a corneal flap about 8.5 to 9.5 mm in diameter
and around 120 microns thick - so that it includes epithelium, Bowman's
membrane, and some stroma.
The flap is intentionally not cut completely so that it has a remaining
hinge, which connects to the rest of the cornea.
He will lift up this flap, like the cover of a book, to expose the
tissue just below the flap's surface, called the corneal stroma. A
significant innovation in this step is the Seibel
IntraLASIK Flap Lifter.
- The VISX 3D ActiveTrak will follow the tiny motions of your eye
instantaneously, in three dimensions, and automatically repositions the
laser to ensure accuracy. You simply need to focus on a special fixation
light for a minute or less.
- Through a series of pulses, the VISX S4
Star Excimer Laser reshapes
the exposed stromal bed by removing a delicate amount of the exposed
tissue. Under Dr. Seibel's supervision, the wavefront computer
software directs precisely how much corneal tissue is removed and where.
- Dr. Seibel then replaces the flap over the cornea. No stitches
are required to keep the corneal flap in place. Typically overnight, the
epithelium cells of the cornea will migrate over the edge of the flap to
seal it.
- Dr. Seibel will remove the drapes and eyelid holder, and apply
antibiotic, anti-inflammatory eye drops.
- When Dr. Seibel tells you to, you may get up from the chair and
rest for a few minutes. Clear protective eye shields will be positioned
over both eyes to protect them from injury. There may be some temporary
discomfort after treatment, similar to having an eyelash in your eye. Dr.
Seibel can prescribe pain medication if necessary, although he has never
needed to do so.
- Your vision will most likely be somewhat fuzzy at first. This
is completely normal. You'll go home to rest and relax for approximately
4 hours to facilitate the healing process of the flap. Someone must be
present to drive you.
