O.R.Vertex Distance (mm):
New lens expected to rotate like the original
✅ Check this if the new lens is expected to rotate like the original (e.g., soft toric, standard toric haptic)
❌ Leave unchecked if the new lens will be stabilized differently (e.g., Maxim3D with back surface control) (rotation is fixed in design)
