Transpose the prescription
-0.75DS/-3.25DCx30 to the toric form with a capstan-form surface which has a +2.50D base curve
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=
what do i do next?
-6.5 DS/ +2.50x130/+5.75x120
