I had LASIK surgery in both eyes in October 2012. I was -6.5 in the right and -6.75 in the left. My left eye only improved to -0.75, so in March 2014, they did an Lasek enhancement. My vision is now worse then what it was, and I was informed yesterday it is +1.5, and can take 3 months to improve, is this normal? Should I go to another practice?
