Purpose: To report (1) results of the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8) among a large sample of SCL wearers before and during 1 year after fitting with one of 2 daily disposable (DD) lenses (etafilcon A or narafilcon B) in the TEMPO Registry, (2) the cut-off score to identify highly symptomatic SCL wearers and (3) the clinically important difference (CID) in the CLDEQ-8 score. Methods: Demographics, CL history and patterns of SCL use were documented. Construct validity of the CLDEQ-8 was tested versus overall opinion (OO) of habitual SCLs, eye dryness and eye sensitivity at baseline. Responsiveness to change in OO was tested. Cutoff score, CID, and predictive accuracy were analyzed with general linear mixed models, adjusting for clustering by site with Bonferoni correction for multiple comparisons. Results: Baseline CLDEQ-8 data from 977 habitual SCL wearers showed significant association with OO, eye dryness and sensitivity (p< 0.0001, all). CLDEQ-8 scores improved significantly after refitting and reflected change in OO over time (p< 0.0001). Diagnostic cutoff of >= 12 and CID of 3 points performed best. Conclusions: The CLDEQ-8 score of >= 12 points is proposed to identify SCL wearers who could benefit from clinical management of their CL-related symptoms. The clinically important difference was +/- 3 points. Refitting to these DD lenses in the TEMPO Registry provided significant and stable reduction in SCL-related symptoms across the year of follow-up. Use of the CLDEQ-8 in clinical practice and clinical research will help quantify and standardize symptom measures in SCL wearers. (C) 2016 British Contact Lens Association. Published by Elsevier Ltd.
