Hi should have fed back ages ago, had my enhancement on 7-Dec-01 as planned, vision still not good in right eye, advised by Manchester clinic to use Viscotears and plenty of drops, which I did, however over Christmas it got progressivly worse. I phoned head office and they arranged an appointment for me at the London Clinic on 30 Dec-01. It turned out I was allergic to the preservative in the eye drops so using loads was making matters worse, a very bad reaction in the right eye. Left eye still great. Given different drops without preservative and gradually the eye got better, forgot to say had silicone plug put in tear duct to assist drops to stay in the eye for longer. Went back for check up in January and given all clear. Vision good in both eyes at long last. Was told I would need glasses for reading but so far manage to read most print without. Still need to use the drops and make sure they are without preservative, some days eyes are better than others but overall results now very good. Denise if you read this, let me know how your getting on.
