Thank you for your message and scrutinous read. Regarding your question, I would adopt a combined approach, in thick lenses, that takes into account the position of the principal planes, and apply vergence calculation on these.

your exposition of pseudophakic optics is tremendous and has helped me a lot.
In your above spreadsheet you subtract instead of add CCT from ILP to calculate ALP. I think by accident.

Besides, I am working on a vergence based calculation method with ELP prediction from personal surgical data and exact IOL data (both toric and non-toric IOL). What is your take on using either principal plane or vergence methods?

Thank you. Best wishes,
