Oh that is so discouraging. I am truly sorry to hear your struggle with the floaters. My experience is very similar. I developed dysphotopsia after my first iridotomy. It is like a small ellipse of light at the bottom of my field of vision. This is in my right eye and this iridotomy was at the 12 o'clock position. After emailing several ophthalmologists across the country -- and doing lots of reading -- I requested that the iridotomy in my left eye be at either the 3 or 9 o'clock position (temporal position). This is what was done and I had NO problems with this eye. Over time, the crescent of light in my right eye has improved but still remains if I am in direct sunlight. You can ask for your opposite eye to be done in the temporal position. I am assuming you had the first at the 12 o'clock position. It has been 7 years ago since I had the iridotomies done. Take a look at my original post for more detailed information. It has been so long since I have thought about it that I can't clearly remember all my details now.
