Difference between "controlled release" vs "prolonged release"
The first box contains Tegretol Retard, which is an old name for what is now known as Tegretol Prolonged Release (medicines.org.uk).

The second box contains Tegretol CR, which means controlled-release (PubMed).

Drugs.com says:


  Your medicine is called Tegretol 200mg prolonged-release
  Tablets/Tegretol CR 200mg Tablets or Tegretol 400mg prolonged-release
  Tablets/Tegretol CR 400mg Tablets but will be referred to as Tegretol
  prolonged-release Tablets throughout this leaflet.


Concluding from that, Tegretol CR200 is the same as Tegretol Retard, which is now known as Tegretol Prolonged Release.

Saying that, it is a doctor who prescribes drugs and who can answer such questions.
