What is the most common side effect after surgery?

Our children have quite poor eyesight.

I'm considering surgery.

It's not that I want to have surgery either.

They say we need to check if surgery is possible.

My eyesight has been stabilized around my surroundings.

They say their eyes have become dry and they can't stop using artificial tears.

Is everyone like that?

Has your vision recovered, so are you reducing artificial tears?
