Hi there! Although no one can make the decision for you, I highly recommend you research an excellent doctor and consult. Astigmatism is a bit trickier from what I experienced.
I had -4.50 with 4.0 astig left eye and -2.75 no astigmatism right eye. Post lasik about a month and a half, as you, I was confused at my left eye being blurry and my right eye being perfect. Granted as you can see I had an astigmatism that caused me to see blurry both near and far. It had been corrected from a 4.0 to a 2.0 and I tried waiting to see how it may improve. At the eye doctor appointment 4 months post surgery I learned my blurry vision in the eye had gone down to a 1.5 astigmatism which is still big. My doc said to come back in another two months to decide if an enhancement should be done. Sure enough at that next appointment it was STILL BLURRY and 1.5 astigmatism. I made an appointment to do my free enhancement. It was way easier the second time around.
The procedure did not have the suction thing and it was very fast. I was still not perfect the day after the procedure or a even a week, but I realized it was a different kind of blur (If that makes sense) It was what I would term the "healing blur" due to swelling. But it suddenly disappeared and 3 weeks after the enhancement I had the GREATEST CRAZIEST VISION EVER. I thought to myself, that's what I'm talking about!" I wanted to go on the board here to share my experience. Not to give false hope, but to let people in limbo with similiar experiences know that it usually can be okay, even if it didn't go perfect the first time. Big hug. Hope this helps you.
