Am I suitable for SMILE?

As an MMA fighter, you should consider a surface treatment such as LASEK which in my opinion would be safer for you than LASIK. Yes, with LASIK a blow to the eye could dislodge your flap, even after 6 months. With LASEK, there is no flap, and you can completely avoid this concern.

Approximately 1-2% of patients who have custom Intralase LASIK will require refinement procedures due to their individual response to the excimer laser treatment. It is our policy to wait three months before refinement in order to assure refractive stability. 

Highly unlikely the edible affected your healing after LASIK, though your eye may have been slightly more red than usual.
