Can a rhinoplasty cause vision problems? I have been having eyestrain/accommodative issues

Hi and welcome to our forum!
The procedure of rhinoplasty does not involve the bony orbits where the eyes and their muscles reside.
However, rare instances of orbital hemorrhage, enophthalmos, exophthalmos, periorbital cellulitis, and blindness have been reported.
The problems you describe, however, may also be caused by the aging process.
As you have experienced a change in your vision, I would recommend a complete eye examination by a board certified ophthalmologist to rule out any orbital pathology.
Best wishes...
