Lens
You can add lenses to the built-in lens database if they aren't there.
But first, please consider these two facts
The built-in lens database is updated via program updates. So please update to the latest version before considering manually entering lenses.
The lens may be listed using a different name than you have for it. This is actually quite common. Please email support@hicsoap.com and ask if the lens in question is already in the database.
If after considering this you can add a lens by
MAIN MENU -> PROGRAM & SURGEON SETUP -> ADD LENS NOT IN DATABASE
