mography (ssOCT) and corneal tomography along with a CSO MS-39. He then goes into the planning and transfer phase with EQ Workplace and EQ Mobile followed by treatment using the LUMERA® 700 with CALLISTO eye®. In the measurement phase, Dr. Findl explained that the greatest source of error when implanting toric IOLs come from imprecisions in corneal measurements for residual astigmatism. “Misalignment and tilt of the IOL also play a role, but the corneal measurements are the main reason especially for patients with moderate or lower amounts of astigmatism,” said Dr. Findl. Because of this, Dr. Findl advises to use at least 2 different devices for measurement: IOLMaster 700 with Total Keratometry (keratometry and ssOCT) and a placido-based topographer (ssOCT).

Digitalization in IOL Power Calculation: My Current Workflow with Toric IOLs Oliver Findl, MD, MBA, Austria With an increasing incidence of moderate or high corne- al astigmatism in the cataract population, Oliver Findl, MD, MBA, Austria, said, “We know that toric lenses are being used more readily and that they result in better outcomes for patients.” However, there is still some work to be done in increasing toric IOL success rates for patients. In Dr. Findl’s current workflow, he takes measurements using the IOLMaster 700 for sweptsource optical coherence toUDVA, corrected distance visual acuity (CDVA), and objective scatter index (OSI). In Dr. Ganesh’s patient population, 95% of patients were within +0.125 diopters of attempted refractive outcome. Additionally, 73% of eyes remained unchanged in terms of CDVA with no eyes showing loss of lines, demonstrating an excellent safety profile. Over a time period of 3 months, Dr. Ganesh found excellent stability in terms of spherical equivalent refraction (SEQ). With improved femtosecond laser technology for performing SMILE for myopic, hyperopic, and astigmatic patients, the VISUMAX® 800 provides a more efficient and quicker workflow for surgeons. The lenticule extraction technique remains the same as the previous VISUMAX® 500 with proven clinical results, so it has “never been easier to start with SMILE,” said Dr. Ganesh. that all relevant operating procedure documentation can be assigned to each respective patient. Dr. Ganesh explained that surgeons can now streamline their workflow and carry out patient data management and treatment planning from anywhere in their clinic. Dr. Ganesh describes his workflow as such: after the patient has been draped, the treatment arm is moved down and the treatment can be selected on the VISUMAX® 800. The machine itself provides a top and side camera view that both assist in docking the eye. The VISUMAX® 800 also has a centration guide, which aids in centering the treatment to the corneal vertex accurately. With a cyclotorsion compensation aid that gets activated after docking, surgeons can align the treatment to the anticipated marks by rotating the machine’s joystick. Automatic cyclotorsion adjustment is also possible if the iris images are imported from the IOLMaster. “The laser treatment is extremely fast,” says Dr. Ganesh, “and takes just 8 seconds to complete.” Lenticule extraction can be performed very comfortably to complete the procedure. Dr. Ganesh shared clinical outcomes from his clinic in which he examined a total of 232 eyes. Two-week follow-up was available for 194 eyes, while 3-month follow-up was available for 41 eyes. Dr. Ganesh used a nomogram with 10% overcorrection for sphere, 15% overcorrection for WTR cylinder, 10% overcorrection for oblique cylinder, and no astigmatism for ATR cylinder. Postoperative outcomes at 2 weeks for 194 eyes showed significant improvement in New Developments in Supplement to EyeWorld Asia-Pacific September 2022 APACRS The news magazine of the Asia-Pacific Association of Cataract & Refractive Surgeons The EQ Mobile application on the smartphone allows surgeons to transfer patient data directly to a computer connected with the microscope in the operating room.
