ABSTRACT
Purpose: To evaluate how covid-19 protective measures in Greece, especially teleworking and use of face masks, affect dry eye syndrome (DES) in contact lens (CLW) and non-contact lens (non-CLW) wearers. Method(s): In this cross-sectional study, two specially modified and reliable (Cronbach's Alpha) questionnaires were distributed electronically. The effects of teleworking, use of face masks and their combination on DES were studied. Amongst others, face mask use and duration, change of workplace and type of CL used were investigated. ANOVA statistics, x2 tests and non-parametric tests were performed. Result(s): 121 subjects completed the study, 44 CLW and 77 non-CLW. In the CLW group, teleworking showed statistically significant higher DES (p = 0.011). Additionally, dryer workplace (p = 0.007) and use of frequent replacement contact lenses (CL) other than monthlies (p = 0.014) increased DES. In the non-CLW group, teleworking (p < 0.0001) and the combination of teleworking and use of face masks (p = 0.003) showed statistically significant higher DES. Longer teleworking hours led to higher DES (p = 0.034) and higher eye discomfort (p = 0.015);when this was combined with face masks, the eye discomfort was even higher (p = 0.038). Finally, in between CLW and non-CLW, when they were under the combination of teleworking and face mask use, a statistically significant difference in eye discomfort (p < 0.0001) and in eye dryness (p = 0.010) was found, with very intense symptoms (p = 0.007 and 0.009 respectively). Conclusion(s): Analogous to international studies, face mask use and lengthy use of electronic devices led to elevated DES in both CLW and non-CLW;the novelty of this study is that examines also the two in combination. The even higher eye discomfort found should motivate CL practitioners to inform CLW and non-CLW better during this covid-19 pandemic. Copyright © 2022
