EW San Diego 2015 3 continued from page 1 improves the accuracy of my toric implants. Even if my preoperative calculations are accurate on the spherical power, it is the astigmatic power and axis due to variables such as incisional effect and posterior astigmatism that are taken into account with the ORA System. This gives me great peace of mind in my toric cases. When the toric implant is in the ideal axis, the ORA System will tell me "no rotation recom- mended" and give me the final predicted astigmatism, which is typ- ically quite close to plano. This has greatly improved my toric outcomes. It has also been helpful in post refractive surgery patients, where the calculations can be challenging. For example, when we have a flattened anterior cornea in a laser-corrected myope, our traditional methods of measuring corneal curvature aren't as accurate as in a virgin cornea. This is why we all get more nervous when we have a post corneal refrac- tive cataract surgery patient, and we want to get as close as possible on the refractive outcome in this patient population who has highly valued being able to do a lot without glasses. Because VerifEye+ Technol- ogy takes into account anterior and posterior corneal curvature, it is of great benefit in these cases. In my premium post corneal refractive cataract surgery cases, it is my goal to get them close enough so they do not need another corneal laser enhancement on an often thin cor- nea (from previous PRK or LASIK), or if they do need an enhancement, it will be a low correction. The ORA System has helped me to achieve this. The VerifEye Technology is now the most common reason I get re- ferrals from other ophthalmologists for post corneal refractive cataract surgery cases. The third category of patients in whom it is especially useful is premium implant patients, who are trying to hit a specific refractive error because their goal is spectacle VerifEye+ Technology alignment reticle VerifEye+ Technology toric placement VerifEye+ Technology LRI overlay. Real-time refractive information (cylinder and axis) is displayed at the top along with LRI overlays on axis, allowing surgeons to see instantaneous impact of the incisions as they are executed. independence. The optics of pre- mium implants require hitting a specific refractive target for ultimate patient satisfaction. Having the VerifEye+ Technology there with me to help in the final implant power choice is of great help. Using VerifEye Technology has greatly reduced our refractive enhancement rate. I like that it now has a dynamic reticle in it. Previ- ously, I would have to stop looking through the microscope and look at the computer screen on the VerifEye Technology cart. Now, I can contin- ue looking through the oculars of the microscope because the dynamic reticle is inside the oculars, and it provides streaming refractive data for alignment information while I am looking through the microscope. This has helped my comfort and efficiency during acquisition of the VerifEye+ Technology data. VerifEye+ Technology works very well in conjunction with Verion System. What's nice about the Verion System is that it allows us, prior to the VerifEye+ Technolo- gy measurement, to get closer to the target refraction than the manual techniques that we used before Verion System. We are finding that the adjustments that we need to make with VerifEye+ Technology after placement of the implant are less because we have the Verion System guidance. It has been exciting to work with the VerifEye+ Technology device and see how it has evolved. Alcon has been very responsive in continuing to improve the tech- nology, and the dynamic reticle is just one example of how the ORA System with VerifEye+ Technology is helping us to optimize our cataract refractive outcomes.
