"Contact lens discomfort (CLD) may be the leading cause of patient dissatisfaction with, and discontinuation of, contact lens wear throughout the world -- but there is little agreement among vision researchers and eye care professionals about how to define and manage its causes," reports Science Daily.

'However, there is no global consensus concerning the definition, classification, epidemiology, pathophysiology, diagnosis, management and the proper design of clinical studies for CLD.' To lay the groundwork for defining and treating this widespread issue, the Tear Film & Ocular Surface Society (TFOS; www.tearfilm.org) organized the TFOS International Workshop on Contact Lens Discomfort (CLD), which was chaired by Nichols. The findings were reported Friday in the current issue of journal Investigative Ophthalmology & Visual Science (www.iovs.org)." Read more.
