Thank you @hopeful33250 for your reply and the links. I am really appreciated it. I will follow the conversation link you provided. I am able to function with current vision problems, but it is not well like before. I cannot drive at night at all and even as a passengers since the incoming cars headlights are too bright for me and I couldn't look straight at all. I can read about an hour and I have to rest my eyes for a while like 3 hours. The worst is I cannot be in the bright room because I see lots of floaters. I cannot look at the white wall or white papers since all kinds of black lines and spots. So I cannot work. It's been almost a year and is not subside. I am very depressed. I was wondering if Corneal Tattooing will help me not to have these vision problems. I would like to have infomation on good doctor who perform corneal tattooing procedure, If you find those information, please let me know. Thanks again @hopeful33250 !
