    IntraLASIK - IntraLase Surgery in Houston, Texas

    Jeffrey C. Whitsett, M.D.
    Houston & Corpus Christi, TX

    The Whitsett Vision Group is now one of a select number of practices nationwide able to offer IntraLASIK using the FDA-approved IntraLase FS laser. IntraLase has the potential to become the key ingredient to optimizing visual results in laser vision correction surgery as I will explain in this article. This technology provides a less invasive, computer-controlled approach to the important first step in LASIK surgery – making the flap

    This step, traditionally performed by a surgical blade called a microkeratome, has now been enhanced by the FS (femtosecond) laser's micron-level accuracy, making every procedure more predictable. By replacing the traditional approach with a silent, tiny beam of laser light to open the flap for actual surgery, IntraLASIK dramatically reduces the risk of complication.

    In fact, more patients may now be candidates for laser vision correction due to this unique level of precision previously unavailable

    More than 100,000 procedures worldwide have been performed with the IntraLase technology. Comparative clinical studies confirm that IntraLASIK offers benefits beyond predictably better vision. At follow-up exams, more patients prefer their vision and see better following laser vision correction with the IntraLase technology. Uniquely precise, uniquely safe, IntraLase gives our practice a new standard of care in LASIK surgery.


    For the past few years, I have used the Amadeus microkeratome and achieved excellent results. Although the percentages are not great, some surgeons have experienced problems with less than optimal flaps.

    When a blade microkeratome is used, the side cut and dissection must be completed before the surgeon can recognize that there may be problem with flap. For example, if a flap is created and the patient moves, a borderline flap may occur. Also, although the initial suction with a blade microkeratome may be good, suction can sometimes diminish as the blade moves across the eye, resulting in a poor flap which in turn produces irregular astigmatism.

    One of the top post-LASIK complaints is dry eye following surgery. In a comparison of 300 cases performed with IntraLASIK and 300 cases performed with a traditional microkeratome, only 15 percent of IntraLASIK patients reported this condition compared to 55 percent of those who flaps were made with the microkeratome.

    An explanation may be that the IntraLase laser allows the surgeon to create a flap more like a postage stamp whereas the microkeratome makes a straight cut that may vary in thickness because of the curvature of the cornea.

    With IntraLase, tight eyelids or deep-set eyes are no longer a concer because the surgeon does not need a lid speculum to keep the eye open. IntraLase uses a small holding device that fits on most everyone’s eyes. In fact, with IntraLase, we are now able to potentially create an even larger treatment zone which has benefits in reducing night-time glare and halos.

    The IntraLase femtosecond laser emits 10,000 pulses per second of 1,053-nm infrared light with an extremely small spot size. One of the major advantages of this laser is that it avoids collateral tissue damage. The IntraLase FS femtosecond laser’s low energy can pass through the outer layer of the cornea unabsorbed, except at the point of its focus. This allows the surgeon to customize the flap by choosing the most appropriate flap diameter, flap thickness and hinge placement.

    At the point of the laser’s focus, a micro pulse occurs, creating an expanding air bubble of gas and water. I will use the IntraLase and thousands of its laser pulses to create a connecting spiral pattern that makes a more precise flap plane. These “micro pulses” can be lined up in different directions to create the flap, side cut and hinge with computer-controlled accuracy. Incisions can be made at different angles allowing for greater precision.

    In other words, the hinge is made last, thus, the flap is essentially developed internally and lifted instead of the harsh blade cross cut of the microkeratome. Also, with a mechanical microkeratome, fluid is needed on the eye to lubricate and lessen friction that could slow the blade’s passage or let it get too hot. Unfortunately, the introduction of fluid during the procedure can produce a complication called edema. The IntraLase FS laser eliminates this problem.
