My wife had eye surgery for the removal of recurring cataract in lens capsule with laser. The opthamologist did one follow up exam the next day. Two months later my wife woke up and couldn't see out of that eye. The same doctor examined her again and diagnosed a detached retina. After multiple procedures since, she has regained some but not all of the vision she enjoyed before the first surgery. Is only one follow up visit after this procedure the usual standard of care?
