However, the roles and responsibilities of health educators in pandemic response are unknown. Researchers examined multiple factors that described how health educators' work priorities and lives have been affected by COVID-19. An electronic questionnaire was administered nationally to health educators to assess the effect of the pandemic on their professional responsibilities, the challenges they are facing, and their fears about the future. Of the 913 respondents, 487 (43%) reported changing work priorities, with 80% of that group (389) sharing that their work priorities shifted focus to COVID-19. Most felt qualified to take on the new job responsibilities, but many feared the inability to get back to previous work roles or for their organizations to financially withstand the pandemic. Regardless of workplace setting or job priorities, health educators are prepared in the skills outlined in the Responsibilities and Competencies for Health Education Specialists, which may have led to their abilities in shifting roles so quickly and effectively. Findings from this study may prepare public health agencies to better use and train health educators for their roles in rapidly shifting public health priorities. To study the corneal flattening effect of cross-linking (CXL) overtime and to look for a potential association with preoperative topographic variables and the central depth of demarcation line (DDL). 201 eyes of 146 patients (mean age of 31.2 ± 7.3 years) with progressive keratoconus who underwent CXL between June 2007 and December 2012 were enrolled in this retrospective study. Follow-up visits were performed at different time intervals for at least 5 years. Preoperative parameters and depth of demarcation line were collected from LaserVision ophthalmology center in Lebanon. Corneal flattening was defined by a change in postoperative
