What is iLASIK?

The Omaha Eye & Laser Institute offers the best laser vision correction procedure known as iLASIK. iLASIK is a revolutionary procedure that combines the advanced wavefront-guided laser vision correction technology of the Abbott Medical Optics CustomVue laser with the safety and precision of the IntraLase iFS laser. The resulting iLASIK is the ultimate laser vision correction procedure, offering unmatched precision and safety.

iLASIK Surgery Suite

At OELI, iLASIK is an all-laser procedure, involving zero blades. Because iLASIK is truly wavefront guided, it can provide sharper vision by addressing higher order aberrations of your vision that glasses, contacts and other forms of wavefront “optimized” lasers simply cannot. We are proud to be the first and only vision center in Nebraska to offer the iFS. Because the iFS is almost three times faster than the older 60Khz IntraLase lasers, our patients experience quicker treatment times and much less discomfort. The iFS laser can create flaps with much smoother beds in a record-low 10 seconds, with the entire iLASIK procedure taking only 10 minutes.

Why Choose Us?

Your eyes are indispensable; you only have two — that’s why it’s important to choose the surgeon that is best for you. Your vision and the health of your eyes are some of your most important assets. Select a surgeon and team who are devoted to your safety and satisfaction, above all else. We recommend making informed choices that prioritize value — not “pricing.” Cheaper is not always better, nor is the most expensive surgeon necessarily the best. Here are some key factors to consider when choosing where to have your iLASIK:

  • Experience
    A seasoned, experienced iLASIK surgeon will be more cognizant of the complexities of laser vision correction than the recent novice iLASIK surgeon will. At the Omaha Eye & Laser Institute, Drs. John and James Liu have been performing laser vision correction since its approval by the FDA in 1995; they were among the first eye surgeons in Omaha to perform iLASIK. Since that time, Drs. James and John Liu have performed iLASIK successfully in tens of thousands of cases.

    In 2003, Drs. John and James Liu became the first eye surgeons in Nebraska to pioneer blade-free iLASIK. Today no one else in Nebraska comes close to having that many years of experience with blade-free iLASIK. Not all eye surgeons will even offer blade-free iLASIK and some who do have little or no experience with the blade-free technology. We recommend caution regarding surgery centers that try to convince patients that there is no difference between LASIK and iLASIK. The truth is there are several differences between bladed LASIK and blade-free iLASIK.

  • Advanced Technology
    Bladed LASIK requires the use of razor blades or microkeratomes, but blade-free LASIK utilizes femtosecond lasers to create the iLASIK flap. Not all femtosecond lasers are created equal, either. OELI and our center in Lincoln (LELI) are the only two centers in Nebraska that use the most advanced iFS IntraLase, which is faster and more precise. This greatly minimizes the duration of the procedure, reduces potential discomfort and improves safety while quickening recovery.

iLASIK In Two Steps

True custom treatment begins with the acquisition of your optical errors using WaveScan technology that can capture even your most minute imperfections. With this information, our team can improve your outcomes beyond 20/20 and enhance experiences like your night vision.


The WaveScan creates a 3D map of the imperfections in each eye so that we can customize your treatment to your individual eye. The WaveScan measures your refractive error 25 times more accurately than standard methods. Your WaveScan map is essentially a fingerprint of your vision.

iLASIK Step 1

Next, the IntraLase iFS laser is used to create a flap in your cornea that is then secured back for the treatment by the VISX STAR S4 laser. This blade-free method allows more patients to see 20/15. The iFS laser is the fastest of all the IntraLase lasers and the most advanced. It is available exclusively at our laser centers in Omaha and Lincoln.

iLASIK Step 2

The captured errors are then used to formulate a wavefront-guided treatment plan that will maximize your vision to its true potential. The VISX Star S4 leaves nothing to chance, and provides active pupil tracking and even compensates for eye rotation in the event of eye movement during treatment.

More About Laser Eye Surgery at the Omaha Eye & Laser Institute

Each patient is meticulously examined to determine the best option for vision correction surgery. For LASIK surgery, the CustomVue Excimer Laser System from VISX is used. Each patient's eye has a unique curvature, similar to a "fingerprint" for the eye. The CustomVue system provides a highly accurate measure of this eye fingerprint, and creates a customized laser profile to correct each eye. To create the corneal flap, the "All Laser LASIK" or "Blade Free LASIK" system from IntraLASE is offered. The combination of the surgeons extensive experience, CustomVue and IntraLASE provides for the most precise and safe result. For those patients who do not qualify for LASIK, the Visian ICL (implantable contact lens) is available. These surgeons also offer the most advanced IOL technology for their cataract patients, the ReSTOR, ReZOOM, and Crystalens lenses, which provide simultaneous correction for reading and distance vision. For implant surgery, they use the highly advanced no needle, no stitch, and no patch technique.

Omaha Eye & Laser Institute is a comprehensive eyecare facility also providing care for eye diseases, such as glaucoma, diabetic retinopathy and macular degeneration, as well as facial cosmetic procedures, such as BOTOX, laser skin resurfacing, and eyelid surgery.
