Iris Registration(IR) approved May, 2005

Goal: Better vision through a more precise placement of the laser beam.

What it does: IR prevents any shift in the laser positioning that may occur as a result of:

• The wavefront measurements being taken while the patient is in a sitting position, versus a lying down position under the laser

• Normal eye movement before and during surgery

• Difficulty in centering the treatment

How it works: Images of the iris are taken during the pre-operative examination. The treatment is centered and positioned using the actual iris patterns of the patient, matched with the photos taken at pre-op.
