I've rewritten my contact lens calculator on EyeDock. The new version does a better bob of showing its calculations by displaying information on optic crosses. It's also more flexible with how it accepts keratometry and refraction input. Lastly, I've added a SPE / CPE lens calculator that uses Thomas Quinn OD's nomograms (the same ones we used to create the GPLI calculator). 

Here's a little video introduction. I hope you find it useful!
