Mr Raisbeck said the nature of the work meant he didn't know what he'd be walking into, in terms of how well equipped the surgeries would be.

Mr Raisbeck said it was humbling to be able to help out in places where eye health and care was less accessible to the general population.
Mr Raisbeck, who is a co-owner of Specsavers Rotorua, was selected because of the store's link with the Fred Hollows Foundation.
The Rotorua store raises money towards the foundation and will soon give customers purchasing glasses the choice between supporting a local charity and the foundation.
