The Keeler Cryomatic MKII trichiasis pencil has been designed for cryo destruction of lash follicles. The serrated grooves on the reusable probe handle facilitate a better grip of the probe and rotation of the probe during use. The tactile positioning groove on the handle allows the user to orientate the tip of the probe while continuing to view the pathology. 
Keeler reusable probes are designed to provide total reliability, with fast freezing and defrosting.
