    Thank you but I have already been on this website and did not find an example of capstan transposition...Are you able to help at all?

    I have transposed the prescription so that it has a plus cyl as we are given a plus base curve=
    -4.00DS/+3.25DCx120
    what do i do next?

    -6.5 DS/ +2.50x130/+5.75x120
