I was moved onto ivabradine about a year ago and for me it has been my miracle drug. It is by no means a cure but it controls my symptoms far better than beta blockers. My query is does anyone else on this drug get vision distortion. In my last eye test I could not read the letters as they were all stretched. I do not notice it day to day, it does not happen close up but I am short sighted but very noticeable on eye test. Opthamology cannot find a physical cause for it so assume side affect from ivabradine as I also get the visual lumina.
