METHOD OF CALCULATING THE REQUIRED POWER OF A TORIC IMPLANT
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.
