title: Non-invasive Tearscope Plus routine for contact lens fitting.
abstract: The Keeler Tearscope Plus was invented by the author as a multi-use instrument for the non-invasive examination of the tear film, its appearance, volume, stability and, its effect on the ocular and contact lens surface. Its use is maximised by following a step-by-step approach described which is based on simple clinical principles of tear film stability.
