"In this year's Binkhorst Medal Lecture, I'll focus on four common clinical scenarios that re- sult in atypical IOL calculations and suboptimal refractive outcomes: long eyes, short eyes, ker- atoconic eyes, and post-refractive surgery eyes," Dr. Weikert said. "For each group, I'll discuss the pertinent anatomic variations, describe the underlying assumptions, address the inherent limitations, review the work we've done to fur- ther elucidate these principles, identify areas for future investigation, and offer practical pearls that you can take home to your practice." Binkhorst Lecture preview M itchell Weikert, MD, will deliver this year's Cornelius D. Binkhorst, MD, Medal Lec- ture at the ASCRS Annual Meeting. Dr. Weikert is a Profes- sor of Ophthalmology and Residency Program Director at the Cullen Eye Institute at Baylor College of Medicine. In his career, Dr. Weikert has published dozens of peer-reviewed pa- pers and has been actively involved in clinical research and teaching. Dr. Weikert has been an ASCRS member since 2001. He currently serves ASCRS as the Cataract Editor of EyeWorld maga- zine, is the ASCRS Skills Transfer Subcommittee Chair, and was recognized by his peers with the 2022 ASCRS Educator Award. Dr. Weikert's lecture will be titled "IOL Calculations in Atypical Eyes: Exploration and Explication." As cataract surgery has evolved, we've been fortunate to gain access to increasingly sophisti- cated diagnostic technologies that have sig- nificantly improved our ability to measure our patients' eyes, Dr. Weikert said. "Coincident with these biometric advances, we have seen similar growth in the accuracy and sophistication of IOL calculation formulas," he said. "In today's practice of 'refractive cataract surgery,' careful combination of high-quality biometric imaging and modern IOL formulas allows us to achieve refractive prediction accuracies of ±0.5 D in up to 90% of patients. Unfortunately, despite these impressive results, we still fall short of this goal at least 10% of the time." While this may not sound like much, Dr. Weikert said it takes on greater significance when you're spending an hour with a dissatisfied patient trying to explain the intricacies of this process and why their expectations were not met. One caveat in the above discussion is that these results apply to normal eyes, Dr. Weikert said. When confronted with anatomically atypical eyes, refractive results can often take a "nosedive," he said. The reasons behind these refractive shortcomings are diverse and include factors such as anatomic variation, mistaken Nicole Fram, MD, presents Eric Donnenfeld, MD, with the award for the Binkhorst Lecture.
