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.
"Up to half of all contact lens wearers experience CLD," explained Jason J. Nichols, OD, MPH, PhD, Professor at the University of Houston College of Optometry. "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; http://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.
The CLD Workshop took 18 months to complete and involved 79 experts from around the world. "Workshop participants used an evidence-based approach and a process of open communication, dialogue, and transparency in order to achieve a global consensus concerning multiple aspects of CLD," noted Mark Willcox, PhD, FBCLA, FAAO, MASM, Professor, School of Optometry & Vision Science, University of New South Wales, and Vice-Chair of the Workshop.
"This TFOS report will significantly increase awareness of factors that may, and may not, contribute to the generation of CLD. Ideally, this TFOS report will stimulate innovative research in this very important field," commented David A. Sullivan, MS, PhD, FARVO,
Founder and recent past TFOS President, Senior Scientist, Schepens Eye Research Institute/Harvard Medical School and Organizer of the TFOS CLD Workshop.
The TFOS International Workshop on Contact Lens Discomfort Report is freely available to scientists and clinicians worldwide. Complete or partial translations of the report will be offered in numerous languages.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
