Are there different sizes of contact shields for CO2 laser treatment of the eye area?

I had a full face CO2 laser treatment last week. They numbed my eyes to put the contact shields in, but they wouldn't fit into my eye orbits. They said something about them being medium size, but didn't try another size. I would hope they make a small size lens for smaller eye orbits, but I'm not sure if this is an option I can request. It wasn't offered. I wore hard contacts in high school with no issues. What can you advise in this situation? Thanks for any help.
