Force gauge used to test integrity of clear corneal incisions

A calibrated force gauge was used to apply pressure approximating what a patient’s eye might experience when it is rubbed, and then that pressure was used to determine the rate of wound leak after clear corneal incision cataract surgery.The study authors used the Dontrix gauge (GAC International), modified by Ocular Therapeutix, to determine a force of 1 oz was needed to approximate patient manipulation of the eye. The instrument can be sterilized and used to provide a controlled, quantifiable amount of force, the authors said.
