I don't know where you live but here in Norwich that sort of timetable is about the norm. I had mine done very quickly after the first referral.
Interestingly we have to be referred by an eyecare professional not a GP. I was referred by the Diabetic eyecare unit when they came around to our Surgery.
Norfolk And Norwich hospital does more Cataract Ops than any other in the country. Over 5000 a year.
Its lifechanging, I've had both mine done. The first one at Kings College in London for which I had to wait nearly 2 years. Second one in Norwich done within 3 months.
No complaints from me.
