Described is a displacement device (8) for displacing a conjunctiva of an eye (2) relative to a sclera. The displacement device (8) comprises a first leg (10), a second leg (11), a bar (12) hingedly coupled to the first leg (10) and the second leg (11) such that the bar (12) can move between a retracted position and an extended position, and a finger (13) coupled to the bar (12). The finger (13) is adapted to displace the conjunctiva relative to the sclera when the bar (12) is in the extended position.
