If refractive astigmatism is 0.75 diopters or less, drop the cylinder and compensate for power as in step e below. d. If refractive astigmatism exceeds 0.75 diopters, determine equivalent sphere and then WebJun 1, 2007 · Rule 1: The spherical equivalent of the SCOR should be close to plano. In our examples above, the spherical equivalents are both plano, showing that the lens power itself is close to correct. This isn't especially helpful because we already knew that, but it does help us understand the SCOR numbers.
