The Visx Star S4 IR Laser System

The Visx Star S4 IR Laser SystemTopeka LASIK Center uses the most advanced Laser Technology available today. We are proud to offer the VISX Star S4 IR Excimer Laser System. For years, VISX has been a leader in vision correction technology. The technology is so safe and precise, that recently, NASA approved it for our United States astronauts. This advanced laser system allows our patients to achieve their personal best vision.

Some of the features of the Star S4 Include:

  • Iris Registration (IR): The first FDA-approved, fully automated, non-contact method of alignment of the correct CustomVue treatment to the corneal site
  • Variable Spot Scanning (VSS): Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times
  • Variable Repetition Rate (VRR): VRR delivers treatment at varying repetition rates, optimizing treatment time
  • ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements
  • ActiveTrak Automatic Centering: Locates, and then automatically sets the treatment center to the Ā­center of the pupil.

The Advanced CustomVue procedure provides the largest range of custom wavefront-guided laser vision correction:

  • Myopia or nearsightedness (with or without astigmatism)
  • High myopia (up to -11 D, with or without astigmatism)
  • Mixed astigmatism
  • Hyperopia or farsightedness (with or without astigmatism)
  • Monovision for presbyopic patients with low to moderate myopia, with or without astigmatism

WaveScan Technology


Capturing your eyes unique fingerprint

Wave Scan TechnologyWaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. This technology has now been applied to laser vision correction, measuring imperfections in the eye never before measured using standard methods for glasses and contact lenses. WaveScan-based digital technology identifies and measures imperfections in your eyes 25 times more precisely than standard methods. In addition, WaveScan digital information is transferred to the laser, driving a new level of precision and accuracy.


Until now, eye doctors were forced to practice one-size-fits-all vision. An off-the-shelf lens can correct your vision fairly well, but it does not correct it precisely. Now, with WaveScan technology, our doctor can customize a correction for the unique characteristics of your vision.

Initially you will meet with our eye doctor for a complete medical evaluation and eye history to determine whether you are a good candidate for the CustomVue procedure. Our doctor will discuss the benefits and risks of the procedure with you. A WaveScan measurement will be taken to map the unique characteristics of your vision. With this map, our doctor will be able to accurately assess whether you are a good candidate for laser vision correction. Anyone who is considering laser vision correction should obtain a WaveScan measurement as the first step. Along with other diagnostic tests that our doctor performs, an individualized treatment plan will be developed to address your unique vision needs.

Once it is confirmed that you are a good candidate and your treatment plan has been created, our doctor will schedule you for a CustomVue procedure. Our doctor will provide details to you on how to prepare for the day of the procedure.

Take your vision beyond glasses, beyond contacts, possibly even beyond 20/20!

Bausch & Lomb Orbscan II

orbscan topekaBausch & Lomb’s OrbscanĀ® II is a diagnostic system that maps the entire corneal surface, and analyzes elevation and curvature measurements on both the front and back surfaces of the cornea.

Unlike other topography systems which scan the surface of the eye at standard points, the Orbscan II acquires over 9000 data points in 1.5 seconds to meticulously map the entire corneal surface (11 mm), and analyze elevation and curvature measurements on both the anterior and posterior surfaces of the cornea.

* Analyzes elevation and curvature measurements on both anterior and posterior surfaces of the cornea

* Capable of detecting and analyzing posterior corneal abnormalities where corneal anomalies first appear

The Orbscan II measures criteria such as keratoconus, pre-keratoconus, and corneal thinning which are essential to refractive surgery. The Orbscan II may help explain decreased visual acuity post-op, and is designed to allow the surgeon to more accurately prescribe re-treatments, if necessary.
The result of the Orbscan II will help determine if the patient has enough corneal tissue for LASIK or another surgical option. Orbscan diagnostics are also used to optimize outcomes in both primary treatments and enhancements.
