I had cataract surgery 3yrs ago. Then last year my right eye felt scratchy and was hazy, thought it was my glasses. On my visit to the eye hospital for a checkup it was revealed I had PCO this was last year. After the lazer treatment for this all was fine until a few weeks ago and am experiencing the same again. I was told it was a one only treatment so am now worried after 12mths it has happened again.
