EW San Diego 2015 4 Figure 3: In this case, the Verion System corrects for 11° of counterclockwise cyclotorsion and ensures the femtosecond arcuate cuts are placed at the correct axis. Figure 4: This toric IOL case demonstrates a situation where both the surgeon's preop plan (Verion System, green) and intraoperative aberrometry (ORA System with VerifEye+ Technology, red) confirm the same alignment axis, indicating no new information present to consider deviating from the plan. and IOL plane. This way, the com- bined impact of all planned arcuate incisions, toric IOLs, and surgically induced astigmatism values can be calculated in a single plan. When we program these mea- surements into the LenSx Laser (Alcon), the interface between the Verion System and the LenSx Laser works well and allows surgeons to adjust for torsional rotation. It also allows us to line up the treatment for the arcuate cuts and the incision quite accurately based on the preop- erative plan, and I've found that to be very helpful. While most patients only have between 0 degrees and 5 degrees of rotation, on occasion, there are patients who have more than 5 degrees of rotation, and the Verion System is currently my preferred way to easily pick that up before performing a laser treatment. Once we bring the treatment into the laser and we bring the patient into the operating room, I will use the ORA System and the Verion System together to fine-tune the placement of the lens. In other words, we have the game plan from the Verion System programmed into our ORA System. Then, we remove the cataract. I will use the ORA System and the Verion System together to do toric lenses. I turn on the Verion System and use the reference marker from it as my alignment aid. I measure the power of the lens implant and the power that I want to adjust it with the ORA System, and I implant the lens. I will dial it to where the Verion System says that the lens should go and double-check it with the ORA System, so they work synergistically. I am finding that even though the exact degree axes may not line up between the ORA System and the Verion System, meaning that the ORA System might say 90 degrees and the Verion System might say 86 degrees, the actual placement in the eye turns out to be about identical, and that's because of the torsional rotation. The use of these systems in combination helps surgeons custom- ize the procedure for each patient so he or she achieves the best outcome. Because the game plan with the Verion System is quite accurate, I don't have to do as much adjust- ment for astigmatism management with the ORA System as I used to have to do before we had Verion System. We still use the ORA System quite extensively to change the lens power, but I am finding that by using the LenSx Laser and the Verion System together, the astigmatism correction is spot on most of the time, and I don't need to do any enhancements for the astigmatism correction using the ORA System. That has been a big time saver for me. Dr. Batra is in private practice in San Leandro, Calif. He can be contacted at drbatra@batravision.com. continued from page 2
