Right, here's the update. Having been told for the last 2 weeks that I must see my surgeon again, they succeeded in putting me in front of 'NOT my surgeon' two weeks running. The second guy I saw lit my fuse when he turned from my notes and asked me which eye I'd had done. So I loudly questioned his credentials and parentage, screamed blue murder (emptying the waiting room and probably precipitating calls to emergency services) until my surgeon magically appeared in front of me. At last, some sanity. She was spot on, explained exactly what had happened and why, and we arrived at an exit strategy. I have now stopped antibiotics but will still use steroid drops for another 20 days, whereupon I will return to my optician for a post-cataract test. I shall then carry the resultant prescription to my surgeon on 18 October, and she will decide whether I can order my glasses, or I slide down the very last snake and we start all over again. Simples!
On a bright note, most of the 'pink eye' has subsided, so I no longer have to endure so many knowing smirks.
