MONTE CARLO, Monaco — Iris registration software for wavefront-guided LASIK results in less cylinder and higher quality vision postoperatively than manual alignment of the eye, according to a multicenter study.

Gustavo Tamayo, MD, said a retrospective multicenter study revealed significantly better postop visual acuity in eyes treated with iris registration than in a manual registration group.

The study compared 285 eyes treated with wavefront-guided ablation with iris registration and 280 eyes that were treated with standard wavefront-guided LASIK.

According to Dr. Tamayo, 50% of eyes treated with iris registration had less postop cylinder than eyes treated with manual registration.

“The study results also showed a significant improvement in postop visual acuity,” Dr. Tamayo said.
