LASIK Surgery


LASIK Surgery In-Depth

 What is laser vision correction?

LASIK surgery is a form of laser vision correction, which is a procedure that improves vision by permanently changing the shape of the cornea (the clear covering of the front of the eye) with a laser. LASIK (an acronym for the medical term laser assisted in-situ keratomileusis) is the most commonly performed type of laser procedure and an effective treatment for a wide range of vision problems.

In fact, all branches of the U.S. Military and NASA have approved LASIK for their servicemen and women thanks to studies using iLASIK technology.

The iLASIK Procedure

The iLASIK procedure combines the most innovative technologies to bring you the next generation of laser vision correction. With iLASIK, we can individualize all steps of your LASIK procedure – custom wavefront diagnosis, personalized laser flap creation, and Advanced CustomVue laser treatment. There is just nothing better on the horizon than iLASIK.

What Kind of Results Can You Expect?

Here are the Results of the FDA clinical study:

  • Clinical studies results showed that one year after treatment:
    100 percent of nearsighted patients and more than 95 percent
    of all study patients could pass a driving test without glasses
    or contact lenses
  • 98 percent of mild-to-moderate nearsighted patients and
    almost three-quarters of all study patients could see 20/20
    or better without glasses or contact lenses
  • Four times as many mild-to-moderately nearsighted
    participants were very satisfied with their night vision after
    treatment compared to their night vision before treatment
    with glasses or contacts.

You’re Probably a Candidate for iLASIK

Although there are some conditions that exclude certain patients, the reality is that the majority of people who are nearsighted, farsighted or have an astigmatism, and meet the general requirements below are good candidates for the iLASIK procedure.

  • You are at least 21 years old
  • You are in good general health
  • You have had a stable vision prescription for at least one year
  • You have no existing eye disease

Eye Conditions Correctable with iLASIK Surgery

Myopia (nearsightedness)

nearsightedness diagram The normal eye is a perfect sphere, where the cornea and lens focus light to form an image on the back inside surface of the eye, known as the retina. With myopia, the cornea’s curvature is too steep for the shape of the eye. The light is focused in front of the retina, causing distant objects to appear blurry.

Hyperopia (farsightedness)

farsightedness diagram In farsightedness, the image focuses behind the retina because the cornea is too flat. In our youth, the lens inside our eye adjusts to compensate for this. As we age, our eyes become less able to accommodate. For this reason farsightedness becomes a problem later in life. Many farsighted eyes do not need correction until the individual reaches age 40 to 50. Farsightedness can be corrected by a method that increases the total refractive power of the eye by steepening the cornea.


astigmatism diagram The front of the astigmatic eye is not perfectly round, but more oval or asymmetric like a football. Incoming light focuses at multiple points instead of one. Astigmatism can make wearing contact lenses difficult or even impossible. iLASIK with VISX is now an option for people with astigmatism who want clear, comfortable vision.

How the iLASIK Procedure Works

Step 1 Creating Your Personal Vision Profile

personal eye vision profile The first step in the iLASIK procedure is to perform a series of tests to determine the individual characteristics of your vision, including the use of our WaveScan technology.

The WaveScan system creates a 3-D map of the unique imperfections of your eyes. Like your fingerprint, it’s one of a kind. Our Advanced CustomVue process uses the digital information from the map to design a custom treatment for each of your eyes.

Step 2 Making the iLASIK Flap

iLASIK flap The iLASIK procedure exclusively uses an advanced technology called the IntraLase Method.

The IntraLase Method is a 100% blade-free approach to creating your corneal flap, the thin flap of tissue that the doctor folds back in order to perform your iLASIK procedure.

Step 3 Your Laser Vision Correction

The Advanced CustomVue process has earned FDA approval to treat the broadest range of vision imperfections possible,including mild-to-severe nearsightedness, farsightedness and all types of astigmatism.

Your vision is as unique as your fingerprints so we use a highly customized approach to providing the optimum match to your vision needs: The VISX STAR S4 Advanced CustomVue WaveScan™ System
