Professor Gerd Auffarth (Germany) and Dr Nino Hirnschall (Austria) discuss the importance of biometry considerations. They explore the reliability and selection of biometric devices, considering various options. The conversation focuses on the evolution of biometric measurements for IOL calculation, moving beyond basic parameters to more detailed and specific eye measurements. The surgeons also examine the question of whether advanced technologies are foolproof and highlight potential challenges that can still occur despite using the latest, most advanced technology.

Professor Gerd Auffarth is one of the world’s leading intraocular lens experts. He is a Chairman of The Department of Ophthalmology, Ruprecht-Karls University of Heidelberg, and the Head of the David J. Apple Center for Vision Research. He also serves as the Director of the IVCRC. In 2018, Gerd ranked second in the The Ophthalmologist’s Powerlist of the World’s Top 100 most influential people in the world of ophthalmology.
Dr Nino Hirnschall (guest)
Dr Nino Hirnschall is an internationally renowned expert in biometry and a surgical consultant at the Kepler University Hospital in Linz, Austria. He completed his training in Vienna at the Hanusch Hospital and has worked in many clinics across the UK and Australia.
- For Prof Auffarth and Dr Hirnschall, there is no longer a gold standard for biometry. In order to obtain accurate measurements, multiple measurements must be taken with several devices and compared, and the medical history of the patient must be taken into consideration.
- Biometry has changed over the years from a simple calculation of a lens to a comprehensive diagnostic system.
- Swept-source OTCs currently provide the most advanced, quality measurements because they allow you to have a bright, sharp image.
- Hirnschall believes that the main source of error for biometry calculations today is the prediction of the position of the lens, but new more modern formulas such as the EVO formula, the Kane Formula, and the Barrett Formula are producing better results.
