3. Purpose and Methods Purpose: To evaluate the efficacy, safety, and predictability of an enhanced laser vision correction surgery (wavefront-guided, iris registration, and femtosecond ablation) on patients undergoing LASIK surgery. Open-label, multicenter, prospective, non-comparative evaluation of up to 20 patients/center (40 eyes/center) scheduled to undergo primary LASIK with the Advanced CustomVue iLASIK (Advanced Medical Optics). Follow-up was at 1 and 3 months. Myopia must be within -0.5 to -6.0 D, cylinder up to -3 D, and MRSE of -6D. Pre- and post-op refraction, wavescan, UCVA, BCVA, and pupilometry will be evaluated. All re-treatment information will be recorded and compared against historical rates. Interim analysis of 131 patients

4. Preoperative & Intraoperative Parameters Mean preoperative cylinder: – 0.565 D (range: 0 to 2.5D) Mean preoperative spherical equivalence: – -2.80 D (range: -0.85 to -5.60) Iris capture success rate – 92.5%

5. UCVA % of Eyes

6. Low Contrast Visual Acuity Post- Op % of Patients

7. Patient Were Satisfied with Their Vision Without Lenses/Glasses % of Patients Four point scale: 4= Very Satisfied and 1=Very Dissatisfied. Note: No patients reported that they were Mildly (score of 2) or Very Dissatisfied (score of 1)

8. Conclusions In this interim analysis, the CustomVue iLASIK platform provided optimal outcomes. – 65.9% of eyes had better than 20/20 UCVA at 3 months – 96.7% of eyes had 20/20 UCVA at 3 months – 100% achieved 20/25 UCVA or better at 3 months No patients have required enhancements to date. Patients were very satisfied with their visual outcomes. – Improved low contrast visual acuity – Patients were able to return to normal activities immediately. 100% of patients were satisfied with their vision
