I have been a Consultant cataract surgeon since 2001.
My experience as a cataract surgeon is extensive. I perform about 500 cataract operations per year. My complication rates are published on National Ophthalmic Database at the following webpage. Copy and paste the bold type into the search bar:
Cataract surgery risks under Mr Shafiq:
This is information on posterior capsule rupture, the commonest type of surgical complication. In my case it hovers between 1 complicated operation per hundred operations to one in 200 hundred operations. This figure is very low and means that 99 operations in every hundred proceed as planned, without complication.
