Severe pain after ReLEx smile eye surgery

I had my relex smile eye surgery on 1 April 2017 but after 3 months I got severe pain in my right eyes and its vision is also getting weak, right now I had power of 0.75. contacted Dr. Several times but no remedy is coming. I am very dissappointed and feeling it's the big mistake of my life. kindly suggest why it is happening? Is it because operation was not done correctly or something else because I had no problem in my left eye
