I am in Glasgow and my hubby had to wait 10 months for his cataract surgery. Waiting lists can be bad here, so you will just have to be patient. The only plus is the surgery is free, so the waiting is the price to pay of sorts. But if you need life saving surgery it is quick, for "normal" procedures you will wait.
The whole cataract surgery took 20 minutes and they do good aftercare. In fact, due to an injury to his eye when he was a kid, he has another appointment, that should have been on the 27th of this month, has been changed to August. Just a fact of life in the UK.
