Smile eye surgery unsuccessful.

Hello, six months ago I had Smile Laser Operation with both eyes. My right eye number was -5.25 and left is -5.00. After six months later the operation, my right eye is -1.00, my left eye is -0.75. My doctor says they can make re-operation after six months later. What is the problem with my eyes and why my numbers are still around -1.00? I can not see clearly with my right eye. Thanks.
