Hello. Please answer my question :( 2 years before my eyesight was almost normal. My eyesight is decreasing rapidly and 1 year ago doctor said that I have an astigmatism and she prescribed contact lenses (approximately: (left)-2,5 and -2(right)) and I was seeing clearly. However my eyesight decrease process continued and 3 weeks later I had (-6, -6,5) and doctor said, I have Keratoconus stage 2 and I need surgery . But i think my eyesight decreased again and today I can t read text with glasses too. I look at computer screen all day. I have an eye strain, eye redness and pain. Also I m seeing heartbeats in my eyes. Please, tell me what I can do to avoid vision loss before surgery? Please :(
