EW SHOW DAILY 36 ASCRS News Saturday, April 14, 2018 by Ellen Stodola EyeWorld Senior Staff Writer into a "black box" and tries to give a better IOL prediction than what was available in the past. Dr. Findl said that over the past 2 years, he has done studies using intraoperative OCT to measure the capsule position after removing the lens during surgery. "From these measurements, we have a better prediction of where the IOL will sit after surgery," he said. The lecture will also cover astig- matism correction and toric IOLs. "Even with torics, we still have some patients with significant residual astigmatism after surgery," he said, adding that new techniques of cor- neal imaging and better calculation of toric lenses will ideally help to achieve better outcomes, especially in patients with low astigmatism. For patients with a small amount of astigmatism, when toric lenses are used, there may be a more surprising amount of residual astigmatism be- cause the corneas are quite spherical and measurements before surgery are not precise enough. The lecture will touch on new technologies to address this. EW Dr. Findl's lecture will highlight the importance of obtaining good biometric measurements and calculations O liver Findl, MD, Vienna, Austria, will give the Bink- horst Lecture today titled, "The Challenge of Choos- ing the Right IOL Power." Dr. Findl shared some of the overar- ching topics his lecture will cover. "I'll start with showing data of how important refractive outcome after cataract surgery is," Dr. Findl said, adding that this is not just important in multifocal and toric lenses but for all IOLs. There are many studies where the quality of vision is assessed by questionnaires, he said, and the number one driver of patient satis- faction after cataract surgery is how close they are to emmetropia. There's no question about the clinical relevance of trying to have the best refractive outcomes, Dr. Findl said, adding that you need good measurements and good calcu- lations. From there, his lecture will highlight how optical biometry has changed biometry compared to the old ultrasound days. Dr. Findl said he is particularly proud of this evolution because optical biometry was first introduced in Vienna, and he was involved in the first trials. He will highlight how optical biometry has changed the way measurements are done and how much more pre- cise they are. He will then discuss some in- novations in biometry, particularly swept source OCT. The advantage, he said, is that you scan the entire eye and get an image of the entire anterior segment. The penetration through dense cataracts is better, so the need to go back to ultrasound biometry is less. Dr. Findl said his lecture will also discuss a recently published study about using swept source OCT biometry that shows a small segment of the fovea OCT image. "It's quite useful to be able to see if there's a problem in the macula," he said. This can help physicians see pathology of the macula that they might not have been aware of before. Dr. Findl's lecture will also delve into the fact that there are still some patients who do not get perfect outcomes. He will discuss analysis of the errors, particularly noting IOL position as an issue. Trying to pre- dict the IOL position and where the lens will sit in the eye after surgery is important because if the position is not the one predicted, you'll be off, he said. Using formulas to aid in pre- diction is another tool. However, this will still contribute to surprises after cataract surgery. He noted that intraoperative aberrometry may be a useful tool because it uses data from thousands of eyes and puts it Binkhorst Lecture to focus on IOL power Oliver Findl, MD On Thursday evening, Nancey McCann, ASCRS director of government relations, gave an industry update on "Regulatory Requirements Under MACRA and Hot Topics"
