Abstract
An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.
