I had my last app may 2018 ,
the last visit I was made to think I was wasting their time, I didn't see a doctor or receive a letter afterward, I went every 6mths 3yrs ago, as a Doctor found a mole at the back of my eye, and wanted to make sure it didn't alter, I have not had an app for 14mths , so my eyes must have suddenly got better and the mole disappeared !
