How LASIK Works |
|
| With the most advanced technology and in the hands of a
skilled surgeon, LASIK is a very safe and quick 4 step
procedure. |
| |
 |
1. Creating a Map of Your Eyes
- Your eyes, just like your fingerprints, are
unique. The specific irregularities causing your
vision to be less than optimal must be precisely
identified in order to produce excellent vision.
Dr. Michael McMann uses the Zywave® II
Wavefront Aberrometer digital mapping system to
capture each eye's unique imperfections with
greater accuracy than ever before. This advanced
technology creates a detailed 3D map of the
cornea's surface which Dr. McMann then programs
into a digital treatment plan which is used to
perform your LASIK procedure. |

2. Creating the Corneal Flap -
Before the laser is applied to the cornea, a
corneal flap must be created. Dr. McMann uses
the XP Microkeratome for this step.
Some LASIK practices say that using a laser
during this step is a better option. Dr. McMann
feels otherwise as with the microkeratome he can
make a clean separation of the tissue, which
results in shorter healing times when it is
replaced. A laser creates a series of small
bubbles beneath the surface of your eye. Then
the surgeon must peal back the flap in a manner
much like separating Velcro, which can result in
longer healing times. |

3. Reshaping of the Cornea -
Once the flap is gently folded back, the excimer
laser is used to reshape the cornea into a round
shape. The laser that Dr. McMann uses is the WaveLight® EX500 Excimer Laser system.
With the precision of this advanced laser, most
patients need a very miniscule section of tissue
removed - about the thickness of a human hair -
to make the correction. This entire process
takes just minutes per eye. During the
procedure, patients may feel slight pressure on
their eyes, however rubbing your eyes, putting
in contacts, or removing contacts will commonly
cause more pressure than LASIK. |

4. Replacing the Corneal Flap -
After the cornea has been reshaped, the flap is
folded back into place where it immediately
begins bonding with the tissue. Healing is quite
rapid and most people can return to normal
activity the very next day. |
