WebWhen using the Barrett Universal II formula, no axial length adjustment is required and standard optical biometry lens constants are used. I highly recommend this approach. The Hill-RBF method also works very well for the high axial myope and requires no axial length adjustment. In its current form, it will return an “in-bounds” indication ... WebThe Hill-RBF Calculator can only be used with biconvex IOL designs for IOL powers from +6.00 D to +35.00 D and meniscus IOL designs for IOL powers from +5.00 D to -5.00 D. For example, anterior chamber IOLs are often based on a convex-plano design and are therefore not suitable to be used in combination with the current release of the Hill-RBF
