I have a problem with eyes

Greetings to everyone who's reading my message. I have a problem with my eyes, and I'm thinking about LASIK surgery. But I'm not sure, is it really as effective as the advertisment says? Here I found some surgeons, can I trust them: lasik eye surgery, lasik online information, lasik surgery, lasik eye surgery in Canada? Maybe somebody can give me any advice? I really need it!
Thank you very much
