hi i have been using crystal meth for over 20 years. I have been having migraines for a few years now so I decided to have lasick surgery . in the past 3 months I have had lasick surgery twice. Both times my eyes are worse than they ever were to start with. My doctor wants to perform a 3rd lasick surgery but I am unsure . Im scared I will come out blind . I can barley see as it is ? Any advice ?
