What are the differences between the lenses?
Traditionally, lenses used in cataract surgery have been monofocal, allowing the user to see well at a single distance. Patients with monofocal lenses usually choose to have their natural lenses replaced with lenses that allow them to see well at distance and wear reading glasses for up close or intermediate work. Recent advancements, however, have resulted in multifocal and accommodating lens implants. Multifocal lenses contain concentric rings that provide focus at different distances. Accommodating lenses bend and steepen as the eye changes focal points. These new style lenses allow the patient to focus at different distances, giving good distance vision, plus improving intermediate or near vision.
