What Underlies Contact Lens-Related Dry Eye?
The authors look at the role of treatments, contact lens materials and care solutions in trying to address the enigma of contact lens-related dry eye. The use of high water content materials was strongly related to dry eye in lens wearers, while care solutions were not.Lubricant Effect on Contact Lens Comfort Discomfort related to dryness sensation is a common problem, too often leading to discontinuation of contact lens wear. The authors use lubricants of 3 different viscosities but conclude that although each helped reduce dryness symptoms with silicone hydrogel lens wear, increased lubricant viscosity did not lead to improved longer-term comfort.Before-and-After Dry Eye Symptoms Are a Clue to Role of Hydrogel Lenses This study looks at ocular dryness symptoms in hydrogel contact lens wearers before and after they are refit with silicone hydrogel lenses. It compares the clinically significant reduction in symptoms in patients who do, and do not, wear hydrogel contact lenses.
