Having to frequently take reading glasses on and off is inconvenient for many people. Because of this, a person might wear reading glasses around their neck, scatter multiple pairs around the house or wear bifocals all the time. With today’s advanced lens procedures, patients now have a choice in the type of lens that is implanted during cataract or clear lens extraction surgery. Unlike conventional “single vision or monofocal” intraocular lenses (IOLs), multifocal IOLs are lens implants that are designed to help patients see at varying distances using different points of focus. The goal of a SmartLens® multifocal IOL is to provide functional vision at different distances to minimize the use of glasses. Although some patients might still prefer to wear glasses for prolonged reading, the vast majority of multifocal IOL patients experience freedom from glasses for tasks such as driving, watching TV, using their cell phone and computer, looking at photos, reading magazines, price tags, product labels, receipts, and menus.
