I want to treat an eye metastasis that is in the muscle with Cyberknife;
What are the pros and cons of doing it in one session vs several (like 4-5)?

It all depends on what the dose to the optic nerve will be

Thank you for your answer. I understand your answer but now I am puzzled. I asked 2 centers if they could do it knowing that one was much more experienced than the other but less convenient for me. One Cyberknife center said they would do it in one session (the more experienced one) and the other in 5 with the same MRI in hands.
Could a difference in machines explain that? They both use the M6 but the most experienced center has the "multileaf" feature.

Most likely just a difference in opinion/judgment. There is not a single right answer
