Hi Lucille
I have been looking at intraocular lenses too. You can now get varifocals and both the UK and New Zealand authorities are happy for an unrestricted class 1 with an acuity report. The operation is far less of an issue too now the lenses are foldable as they are effectively inserted through a needle as opposed to a fully open procedure. A colleague of mine went through this 2 years ago and was very pleased. As always choose your surgeon carefully, and have deep pockets
