hello and welcome to HCM,
I have understood your problem regarding nose surgery
, eye surgery
and vision blurring.
Unless the nose cauterization
surgery involved a procedure called the FESS then it is very very unlikely that the surgery can affect the vision in any way.
In FESS however your vision can be affected especially if these were extensive sinusitis and the procedure took a long time and is usually done under general anesthesia so it should not have been painful.
Nose cauterization surgery however is a very small procedure which if done under local anesthesia
can be painful but is very unlikely to cause vision loss
However any surgery however small can cause vision loss either directly or indirectly but this instance is very rare.
You need to consult your ophthalmologist immediately so that he can confirm the proper cause of vision blur and initiate proper treatment.
