Abstract
A contact tip for a contact tonometer has a body including a contact surface, and a coating applied to the contact surface. The coating includes a light-activated material and a biocompatible water soluble adhesive for adhering the coating to the contact surface. The water soluble adhesive dissolves upon contact with the corneal tear film during a tonometric measurement, thereby releasing the light-activated material into the tear film. The present disclosure further provides a single-use tonometer contact tip product which includes a sterilized contact tip having the mentioned contact surface coating, and an opaque package containing the sterilized contact tip.
