Abstract
A non-reusable lens cell for a surgical laser handpiece having a contact surface with an aperture for exiting a laser beam includes a housing having a first connector at a first end for engaging a laser source and a second connector at a second end for engaging a handpiece; and a hydroscopic lens device for focusing the laser beam through the handpiece proximate the aperture and being degradable in the presence of moisture during attempts at sterilization to deteriorate the lens device, disrupt the focus and thwart reuse of the lens cell.
