You can't remove or delete a lens from the Active Lens List that has been used. You can, however, move it down in the Active Lens List far enough that it doesn't show up when you print out the IOL Calc screen.
- MAIN MENU -> PROGRAM AND SURGEON SETUP -> SURGEON LENS SETUP tab
- Highlight a lens and then click MOVE DOWN enough so that the lens is no longer numbered.
The lens highlighted with red are inactive. They won't show up on the IOL Calc screen.
