Partner Since 2013: A supplementary, sulcus-fixated IOL for pseudophakic eyes—implanted in addition to the primary in-the-bag lens. A Refractive fine-tuning: Corrects residual sphere/cylinder after cataract surgery when corneal laser isn’t ideal (thin cornea, severe DED, prior LASIK). Staged presbyopia upgrade: Lets you add EDOF/multifocal function later without exchanging the primary IOL—reversible if not tolerated. Risk management: Avoids IOL exchange (capsular risks) and preserves the original in-the-bag implant.
