The TFOS International Workshop on Contact Lens Discomfort: Introduction
MetadataShow full item record
For many years, the contact lens field had focused on safety associated with contact lens wear—and for good reason, given the lack of understanding of the risk factors and etiology of serious complications such as microbial keratitis. However, as knowledge came to light on these complications through the 1980s and 1990s, it allowed for practitioners to become more comfortable managing these complications, along with the introduction of products that helped reduce or prevent some of these problems. It was during this time, beginning in the mid-1980s, that the field itself became cognizant of the issues associated with comfort, or discomfort, during contact lens wear. Since that time, we have witnessed the field (and industry) shift its attention toward understanding the issue of contact lens discomfort (CLD). Contact lens discomfort is a substantial and burdensome problem experienced frequently by contact lens wearers. It is well established that most contact lens wearers experience CLD, at least occasionally, although many experience CLD to such a severity that they feel compelled to alter their wearing habits. Common, although palliative at best, treatments include the periodic use of rewetting drops, contact lens removal, contact lens refitting (using different lens designs or materials or replacement schedules), and changes in the contact lens care solutions or regimens, in addition to other less commonly used approaches including topical or systemic medications, alterations in diet, and punctal plugs. Ultimately, CLD is the primary factor associated with permanent discontinuation from contact lens wear. Given the importance of the issue of CLD to both patients and practitioners alike, the time was right to move the field forward by taking steps to bring global consensus to our current understanding of this condition.
