  • System and method for determining intraocular lens power
    Patent number: 10555667
    Abstract: The present invention discloses systems and methods for determine preoperative estimation of postoperative IOL position (or the EAPD) in accordance with one or both of the following mathematical relationships, which are derived from linear regression: EAPD=S1+(S2×AND)+(S3×NT)+(S4×AL),??(1a) EAPD=W1+(W2×AND)+(W3×RND)+(W4×AL),??(1b) where S1, S2, S3, and S4 for equation (1a) and W1, W2, W3, and W4 for equation (1b) are statistically derived linear regression constant coefficients.
