Is it going to be an issue if I was squinting while they were doing measurement for cataract surgery?

How important is it if you've squinted during refraction/measurement tests in preparation for cataract surgery (a procedure in which a clouded lens is removed from the eye and replaced with an artificial intraocular lens to restore clear vision)? Should the refraction be done again to ensure a correct lens?

The refraction is not critical in the plan for execution of cataract surgery. It is good to have a fairly accurate refraction but squinting or not being sure of your answers while being refracted will not affect the surgery or the plan for surgery.
