What is Iris Registration Technology?

It's the first fully automated method of aligning and registering wavefront corrections for CustomVue treatments. It's normal for the pupil to shift positions from the point of wavefront measurement to the point of treatment. Iris Registration Technology centers the treatment correctly, independent of changes in the pupil center from measurement to treatment. It also torsional (clockwise or counterclockwise) aligns the treatment automatically. Auto registration relies on computer programs and infrared cameras that take pictures of the iris when the wavefront measurement takes place in the office setting. In addition the VISX S4 IR laser has infrared cameras and computer programs to match the VISX S4 IR laser captured iris image to that of the wavefront machine's previously taken in the office. This assures that when a person lies down under the laser when there eye cyclo torts (rotation of the eye in the socket clockwise or counterclockwise) that the laser head optically rotates to realign perfectly with the eyes position present in the office wavefront measurement setting. With auto tracking if you move your eye while the laser (VISX S4 IR) is on the laser head follows the movement. With auto centering the laser (VISX S4 IR) treatment is automatically aligned with the center of the pupil that was measured at the time when the person had the wavefront measurement in the office setting.
