kingreyna, I actually have a pretty high astigmatism. In fact, since my eyesight is 20/50 in my right eye and 20/40 in my left, astigmatism is actually my biggest problem. I don't know about my left eye but, I think my doctor said I am 3.1 astigmatism in my right eye. I just found out that I am a candidate and am scheduled for my surgery this coming Wednesday. I don't know anything about intralasik. I am having LadarVsion Lasik. I don't know if that is the same thing. I have read and learned alot on the internet and from what my doctor explained to me. If I were you, I would just go to a Lasik skilled doctor and have him help you find out if you are a candidate. As far as the sitting too close to a TV or playing video games goes. I really don't think that that is a factor in your poor vision. People do more reading than video games all through life and if that doesn't harm your vision, I can't imagine much would. Like cookiepls said, it is a hereditary thing. Go to a doctor. Someone with thousand of procedures under their belt who costs a good amount of money per eye. Check the LasikPlus website. They may have a doctor in your area. They are probably the best known, most experienced, and well-regulated doctors of Lasik. I may be biased because they are who I am going to but, everyone that I have spoken with, from Ohio, California and in my home state of Georgia has heard of them.
Good luck!
