LASIK Questions

What is laser vision correction?

Laser vision correction 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. Often referred to as LASIK (an acronym for the medical term laser assisted in-situ keratomileusis), it is the most commonly performed type of refractive procedure and is an effective treatment for a wide range of vision problems including nearsightedness, farsightedness and astigmatism.

What is an excimer laser?

The excimer laser technology utilizes ultraviolet light to precisely reshape the inner layers of the cornea. This reshaping is capable of correcting mild to moderate ranges of nearsightedness, farsightedness and astigmatism using the CustomVue™ procedure.

How does the laser know what to correct in my eyes?

Laser vision correction is based on precise measurements of the unique imperfections in your vision. These measurements are taken with a powerful measurement tool known as the WaveScan™. The WaveScan™ information is transferred to the laser to guide the treatment. Dr. Larson was the first LASIK surgeon in Sheboygan to offer this advanced measurement tool to individualize your vision correction treatment.

What is a WaveScan™ and a WavePrint™ Map?

WaveScan™ technology provides a measurement and a visual representation of your vision based on the behavior of light waves. It compares light passing through your eye to the same light pattern from an eye that needs no vision correction. The WavePrint™ Map is the output of the WaveScan™. It captures the unique imperfections of each person’s visual path.

How accurate is WaveScan™technology?

WaveScan™ technology identifies and measures imperfections in an individual’s vision 25 times more precisely than standard methods used for glasses and contact lenses.

What is CustomVue™ laser vision correction?

VISX CustomVue™ is an individualized laser vision correction treatment that is WaveScan™-guided. This enables a doctor to measure and correct unique imperfections in each individual’s vision that could never be measured before with standard methods used for glasses and contact lenses. With the CustomVue™ procedure, nearsighted, farsighted and astigmatic individuals have the potential to achieve a new level of vision that we call Personal Best Vision.

How does the CustomVue™ procedure work?

First, the WaveScan™ technology measures the imperfections in the eyes and produces a WavePrint™ Map. Much like a fingerprint, no two WavePrint™ maps are alike. The doctor uses the information to fine-tune the procedure thereby providing a new level of precision and accuracy. Then the treatment information is transferred to the VISX STAR S4™ laser.

What can the CustomVue™ procedure do for me?

As shown in the clinical study, CustomVue™ has the potential to produce better vision than is possible with glasses and contact lenses. It tailors a distinct correction for each individual–in fact each treatment is “designed” by the unique characteristics of your individual eye.

Is CustomVue™ LASIK FDA approved?

Based on the clinical study, the U.S. FDA has approved the CustomVue™ procedure as safe and effective for treating nearsightedness, farsightedness and astigmatism.

What are some of the results of CustomVue™ to date?

In the FDA study, one year after the VISX CustomVue™ procedure:

  1. 100% of participants could pass a driving test without glasses or contact lenses.
  2. 98% of participants could see 20/20 or better without glasses or contact lenses.

In addition, many participants reported that they had clearer, better vision both during the day and at night, compared to their vision with glasses or contact lenses before the procedure.

Can the CustomVue™ procedure improve my night vision?

Yes, potentially. In the clinical study, four times as many people were very satisfied with their vision at night after the procedure as compared to their night vision before the procedure with glasses and contact lenses.
