Intralase IntraLASIK Precision Laser
Technology
IntraLASIK has changed the way LASIK is performed - offering the safest, most precise vision correction available in the world today!
Due to a new advance in technology, LASIK at Seibel Vision Surgery is
now even safer. Dr. Seibel was the first in Los Angeles to combine the advancements
of IntraLASIK and VISX CustomVue Wavefront ablation. Together these two technologies offer a whole new level of safety to vision correction surgery by providing an all-laser approach. |

 The
IntraLase FS laser is the first technology for a truly all-laser, blade-free
LASIK procedure, replacing the hand-held microkeratome blade historically
used in creating LASIK corneal flaps -- the first step of the procedure -- with a computer-guided, ultra-fast femtosecond (fem-to-second) laser. The IntraLase laser virtually eliminates the majority of the most severe sight-threatening LASIK complications related to use of the microkeratome and, by creating an optimal corneal surface below the flap, provides for better visual outcomes -- taking
many patients to 20/20 vision and beyond.
Traditionally, the creation of a corneal flap, required in LASIK surgery,
was performed with a mechanical, hand-held device (known as a microkeratome)
that moved across the cornea to cut the flap (see animation below). Although
mechanical microkeratomes are safe, they produce a meniscus-shaped flap of
variable overall thickness and always thinner in the center than at the edges.
Occasionally a corneal abrasion or an irregular, incomplete, or button-hole
flap results. Using the Intralase IntraLASIK laser takes LASIK safety to
the next level by significantly reducing the chance of that complication.
The IntraLASIK procedure requires the use of two lasers, providing an
entirely new level of safety and precision in vision correction. While the
IntraLASIK procedure continues to require a corneal flap, it is created with
the a special rapid pulse laser called a femtosecond laser. The corneal flap
is then lifted and the VISX Star S4 excimer laser is used to perform the
actual vision correction. |
To make the corneal flap using the IntraLASIK laser:
-
A laser beam is focused at a precise depth, into a tiny spot of energy
that passes harmlessly through the outer layers of the cornea until reaching
its exact focal point within the central layer of the cornea.
-
Cornea tissue is separated by hundreds of thousands of tiny three-micron sized bubbles.
-
The flap is lifted to allow for the CustomVue laser treatment.
-
The flap is placed back into its original position after the excimer laser treatment.
|
The Intralase laser can make corneal flaps as thin as 100 microns, less
than the thickness of a human eyelash. This may allow people with thinner and
flatter corneas, who weren't candidates for LASIK, to be able to undergo IntraLASIK.

Three Key Advantages:
- Instead of using a mechanical microkeratome, IntraLASIK uses a high-tech femtosecond (FS) pulsed laser to create the corneal flap. With IntraLASIK, only the laser touches the eye. The result is a more precise cornea resection, greater consistency of flap thickness and reduced potential for infection or complication. In addition, when the flap is replaced once the procedure is complete, the tissue "reseats" with a tighter seal. No stitches are used.
- All LASIK procedures require the eye to be immobilized with a suction ring while the flap is produced, which creates a build-up of pressure on the eye. While the mechanical microkeratome places a substantial amount of pressure on the eye, the IntraLASIK procedure allows the eye to remain at a level as close to normal as possible, increasing patient comfort and safety.
- IntraLASIK is gentle to the eye. During corneal re-shaping, the long wavelength of the FS laser allows the beam to pass completely through the outer tissue of the eye without heating or damaging any healthy surface area. The cornea flap is created in a process called photo disruption, which uses microscopic bubbles of carbon dioxide and water vapor to create precise, computer-controlled slices to reshape the cornea to the correct proportion.
The microkeratome is a razor-like device operated by hand or a motor. The blade slices off a portion into the cornea, leaving an uncut section to serve as the flap's hinge.
Dr. Seibel feels that added safety is always worth the investment in technology. Studies have shown that the all-laser approach, utilizing the Intralase IntraLASIK laser and an excimer laser, not only avoids microkeratome-related complications, but also offers the potential for better vision after LASIK. |
