Talk to Eye Specialist on Weak Eyesight

I have undergone 2 lasik surgeries. One the initial one and then the enhancement after two year. But after 1 year of enhancement my vision got weaker again. I am 29 now and wearing glasses again. During the surgery they left a minor number as they said my vision won't be a 6/6. My question is should I go for the enhancement procedure again? Kindly respond to my question. Thank you.
