　　PURPOSE :

　　To assess the improvements in clinical outcomes based on implementing automated iris registration tech! nology with CustomVue wavefront-guided ablations.

　　METHOD :

　　Two cohorts were treated to analyze improvements in clinical outcomes of wavefront-guided ablations using new iris registration technology. The first cohort of 26 eyes was treated with automated iris registration and the pre-operative MRSE was -6.6D. The second cohort of 29 eyes was treated without automated iris registration technology. Pre-operative MRSE of the second cohort was -6.36D.

　　RESULTS

　　In the automated iris registration group, mean cyclorotation was measured at 2.07 degrees. At one week, 77% of patients achieved a UCVA of 20/20 and 96% achieved 20/25. Mean MRSE at one week in the iris registration cohort was -0.49D. In the non-iris registration cohort, at one week 79% of patients achieved a UCVA or 20/20 and 90% achieved 20/25. Mean MRSE at one week in second cohort was -0.08D.

　　CONCLUSION

　　Early results demonstrate slightly improved! visual outcomes but most importantly increased safety with new automated iris registration technology upgrades. Automated iris registration optimizes clinical outcomes through alignment of wavefront map and laser ablation in all axes.
