To validate the safety and effectiveness of combining physician and nomogram adjustments with iLasik to achieve the desired refractive outcome.
Retrospective review of 67 eyes which have undergone CustomVue LASIK with both nomogram and physician adjustments. Preoperative exam will include UCVA, BCVA,MR, WS Refraction. The last visit for data collection was at least one month after the iLasik procedure at which a manifest refraction was performed. Endpoint parameters were UCVA, BCVA, delta MR - target. Statistical analysis included eyes within .25.50 and 1.00 diopters of target as well as eyes with gains and losses of BCVA.
79.1% of patients were targeted for plano. At the follow-up visit, the majority of patients (70%) were within 0.25 D of the target, 95.5% were within 0.5D, and 100% were within 0.75 D of their targeted refraction. Mean SE was -0.3D. Most patients (61.2%) achieved a UCVA of 20/20 or better, and 86.6% achieved 20/30 or better. 98.5% of patients had a postoperative BCVA of 20/20 or better.
The combination of nomogram and physician adjustments with iLasik allows patients to receive treatment with the VSS algorithm who would not otherwise be able to derive the inherent advantages of this treatment.
