MORE ABOUT HOW IS LASIK DONE ?
|
|
LASIK is performed in a reclining chair in an outpatient
surgical suite. First, the eye is numbed with a few drops
of topical anesthetic. These drops may sting. An eyelid
holder (called a speculum) is placed between the eyelids
to keep them open and prevent you from blinking.
|
 |
A suction ring placed on the eye lifts and flattens the
cornea and helps keep your eye from moving. You may feel
pressure from the eyelid holder and suction ring, similar
to a finger pressed firmly on your eyelid. From the time
the suction ring is put on the eye until it is removed,
vision appears dim or goes black.
|
An automated microsurgical instrument called a microkeratome
is attached to the suction ring. As the microkeratome
blade moves across the cornea, you will hear a buzzing
sound. The microkeratome stops at a preset point, far enough
from the edge of the cornea to create a hinged flap of
paper-thin corneal tissue.
 |
The microkeratome and the suction ring are removed from
your eye, and the flap is lifted and folded back.
As the flap moves, your vision gets blurrier. The laser,
preprogrammed with measurements customized to your eye,
is then centered above the eye. In most cases, a pupil tracker
will be used to keep the laser centered on your pupil during surgery.
|
|
You will stare at a special pinpoint light called a fixation
light or target light while the laser sculpts the exposed corneal
tissue. The laser makes a clicking sound that can be heard during
the procedure. After the laser has completed reshaping the cornea,
the surgeon places the flap back into position and smoothes the edges.
The flap adheres on its own in two to three minutes.
