Can you get an eyelash lift/perm a few days before getting eye surgery?

0.25 D is not considered a large enough change to call your prescription unstable. 0.25-0.50D changes are still considered within range when establishing stability. I would recommend going in for a LASIK consultation to see if you would be a good candidate for LASIK.

It is probably ok to get the lash extensions 1 week after Lasik, but I recommend that you wait about a month. No sense in irritating things at this early healing phase.

Most surgeons would think that 1 week is too early to judge. Most do heal faster depending on many issues including whether they had tried plain contact induced monovision before.There are lots of points your surgeon will be considering but be sure to discuss your concerns with them.
