  • Method of calculating the required power of a toric implant
    Patent number: 8764822
    Abstract: A method for calculating the required power of a toric implant by using both the measured pre-operative corneal astigmatism and the predicted surgically-induced post-operative astigmatism. The surgically-induced post-operative 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 post-operative refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.

  • Method of calculating the required lens power for an opthalmic implant
    Patent number: 7476248
    Abstract: A method for 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.
