Is it normal to suddenly see halos and glare 2 months after PRK?

Halos and glare are normal after PRK. Typically the symptoms are the worst the first few months after surgery. However, they should begin to clear up around month 3. If the halos and glare are sudden and enough to cause difficulty with night driving, please visit your doctor to ensure that you don't have any scarring as a result of inflammation. In the mean time, please make sure your eyes are lubricated (preservative free tears every 2-3 hours). 

It can take a while for halos and glare to go away post-PRK.  I find that most patients start to see less issues with halos and glare around 3-6 months post-PRK and that they have the most trouble with halos and glare between months 1-3 post PRK.  A really thick re-wetting drop will often help in clearing the vision temporarily.
