Why is Iris Registration Important?

updated

Laser vision correction has come a long way over the past decade. Dr. Jeffrey Martin, lead surgeon at our Long Island LASIK practice, explains that we are doing bladeless custom LASIK on all of our patients today. This method of doing LASIK is called iLASIK. With iLASIK, the flap is made with a blade-free laser that is the most precise and safest way to make a flap. In past years, the microkeratome blade machines were the major reason for significant complications in rare cases.

With CustomVue, the laser vision correction portion of the LASIK procedure is customized to each patients specific visual system much like a patient's fingerprint. During LASIK laser eye surgery, the laser automatically centers and automatically tracks and also uses iris registration in every possible case.

The significance of iris registration is important to understand. When we change positions from sitting to lying down, the eye can rotate up to ten degrees. In a custom ablation, ten degrees can make a difference in the final result. With iris registration, the laser takes note of each patient's individual iris landmarks and places the laser vision correction based on those landmarks. This gives us the most accurate match and therefore, the best possible result.
