How long will it before I am able to see clearly after 2 months post PRK? Still seeing double, very frustrating

I would recommend applying cold compresses, instead of warm, directly to closed eyelids. This should help with swelling, bruising, and discomfort. Since blood vessels constrict in cold temperatures, blood flow is minimized, and swelling will be reduced. 

First of all, I would recommend that you return to your PRK doctor, or at least an ophthalmologist or optometrist, rather than urgent care, which are not eye doctors. But getting elbowed should have no long-term effect on your PRK results.

Advanced Surface Ablation is a variation of PRK. I would expect little further change 1.5 years after treatment. Most likely, there is some astigmatism which could be corrected by another treatment. Maybe a second opinion is in order.

Hyperopic PRK corrections will require more time to heal compared to myopic corrections, so it may take up to 3 months for vision to be very sharp. To speed up your healing, I recommend using preservative free artificial tears every 2 hours, getting plenty of rest, 1000mg Vitamin C daily, and s...

I would suggest that you go back to the eye doctor and have them perform a cycloplegic refraction. That would be the best way to determine if you are over-corrected. Good luck

I would recommend bringing a driver to your appointment. Typically vision should be clear enough to drive 1 week after PRK, but that is not the case for everyone. Vision may decrease slightly after the contact lenses are removed.
