    Center thickness fomulae with base curve into account OR chart

    Before I decided to post this, I searched through the web and this site but didn't find exactly what I am looking for. I would like to know if somebody can help me with the center thickness formula which also takes BASE CURVE into consideration . The only formula which I found on this site and elsewhere is:
    Thickness = (1/2*Diameter)^2*Power / [2000*(Index - 1)]
    However it doesn't have base curve variable in it. So basically I want to consider Power, Base Curve, and Material variables, even if one changes it will have impact on the center thickness. Some powers may end up having more that one choice of base curve, that's fine.

    For Lab technicians out there, even if there is lab chart that I take a look at from +10 to -10 sphere range approximately which reflects my scenario. Will still do me a huge favor.


    If anybody could help, that would be great. Thanks.
