For patients with cataracts and/or presbyopia there is refractive lens exchange with the AcrySof Multifocal lens, which corrects both distance and near vision at the same time, eliminating the need for glasses after surgery in most patients. Clinical trials showed that over 80 percent of patients receiving this lens never required glasses for any task following surgery.
Finally, quality vision and true freedom from glasses for 80% of patients
During the AcrySof® Multifocal IOL clinical studies, patients experienced lifestyle enhancement through quality vision, and greater freedom from reading glasses and bifocals. In fact, according to the AcrySof® Multifocal clinical studies, four out of five patients with the AcrySof® Multifocal IOL reported never wearing glasses following cataract surgery in both eyes, compared to only 1 out of 10 patients with monofocal lenses. This is the highest level of freedom from glasses ever demonstrated in an IOL clinical trial.
Additionally, the AcrySof® Multifocal clinical studies indicated that nearly 94% of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® Multifocal IOL implanted again.
How it Works
The AcrySof® Multifocal IOL is a multi-focal lens that contains a unique mechanism to provide both distance and near vision.
The apodized diffractive optics comprises 12 concentric “steps” around the optic zone of the lens. These steps, which appear as rings in the diagram to the right, create different focusing levels from near to distant vision.
