LASIK Step By Step:
Step One: Intralase Laser to
Create the Flap
After topical anesthetic eye drops are placed in
the eye to minimize sensation, the eyelids are secured in the open position using a ring
which fits snugly on the eye. You will not feel pain during this stage, however,
vision will darken during the time the suction is applied and there may be a slight
pressure sensation. The Intralase laser is silent and the flap is created in less
than 25 seconds. After this procedure the patient sits in a dark room for
approximately 15 - 20 minutes before Step Two.
Step Two: Excimer Laser
for Vision Correction
With the flap folded back, the excimer laser
removes an exact pre-determined amount of tissue from the center of the cornea. The
computer controls the amount of laser treatment based on your prescription. During this
stage, Dr. Sacks will ask you to look at a blinking red light to allow for proper
alignment of the laser as the laser is focused on the corneal surface (stroma).
Flap Replacement:
Lastly, the flap is returned to its original
position where it quickly begins to adhere to the underlying tissue (stroma). It is
allowed to air dry for approximately 2-5 minutes. There is usually no need for sutures.
Dr. Sacks has access to 3 different FDA approved
lasers at the laser center. Although he most frequently uses the WaveLight
Allegretto Wave™ Laser, the VISX and Alcon Ladar Custom Conrnea Lasers are available.
