摘要： In one aspect, the present invention provides an intraocular lens (IOL) that includes an optic comprising an anterior surface, a posterior surface, and a plurality of diffractive zones disposed on one of those surfaces. The surface having the diffractive zones has a profile characterized by a combination of aspheric and toric components.

摘要： Proper selection and centering of an intraocular lens (IOL) is provided. An image of an eye, which may be captured (72) during pre-operative tests and provided to a program (32) operable to calculate (76) the power and axis orientation of the IOL, is used to determine the location and orientation of the IOL. This produces (78) an image output or placement guide used to properly center and orient an IOL within the eye (80).

摘要： A method of calculating the required cylindrical power of a toric implant by using both the measured pre-operative corneal/ocular astigmatism and the predicted surgically-induced astigmatism. The post-operative corneal/ocular astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required spherocylindrical refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.
