Iris Registration Iris Registration In 2005 the Laser Eye Institute became the first center to utilize the Iris Registration technology in the state of Michigan. Iris Registration is the latest addition to the CustomVue procedure by VISX. It further improves on the CustomVue procedure by adding three key technology improvements. Key Benefits of Iris Registration: Accurate Alignment Iris Registration uses unique matching points on the iris (colored ring around the pupil) to accurately align the treatment on to the cornea. This is needed because a patients head may be tilted slightly from when the original wavescans were created. Previously the surgeon had to make a small mark on the eye, this method was not nearly as accurate as the process of Iris Registration, yet, most surgeons still use this outdated method. 3D Active Track Iris Registration offers the latest generation of active eye tracking. This new tracking system tracks the eye in all 3 dimensions offering unparalleled amount of tracking. The Active Track system ensures that the eye is properly aligned before allowing the cool beams of the laser to discharge. Patient Iris Verification The final feature of the Iris Registration uses Iris Verification to ensure that the correct treatment is applied to the correct patient. Only with VISX CustomVue LASIK Iris Registration technology is only available on the VISX Star S4 laser with Iris Registration. Currently the Laser Eye Institute is one of only a handful of centers to offer the Iris Registration technology. Iris Registration is our standard, and carries no extra fee.
