TECNIS PureSee IOL

About this webinar

Dr. Matt Hirabayashi helped bring the TECNIS PureSee to market, and here he explains how the extended depth-of-focus lens works and which patients it suits in a presbyopia-correcting practice. Dr. Robert Weinstock and Dr. William Wiley host.

His argument rests on contrast. The PureSee sits on the TECNIS platform, whose reputation was built on sharp, high-contrast images, and Hirabayashi explains how that is achieved. The lens material has a low refractive index and a high Abbe number, which keeps chromatic aberration in check and avoids the flickering, cat-eye glare some patients complain about, and it corrects the roughly +0.27 µm of spherical aberration found on average across the population. He weighs monofocal, diffractive, and extended depth-of-focus optics against one another, then closes with practical notes on choosing patients and disassembling the nucleus for fellows still finding their footing in refractive cataract surgery.
