Abstract
A bifocal intraocular lens is described which has been surgically implanted in a number of patients in the United States and Europe with promising results. The posterior surface of this lens includes a blazed phase zone plate which directs most of the light to two diffractive orders. The combination of this diffractive structure and the conventional refractive surfaces of the lens provides simultaneous bifocal vision for the patient.
