Academic Article
Overview
abstract
OBJECTIVES: Beginning in January 2023, numerous eye drops were recalled following reports of contamination. To investigate hesitancy in topical therapies for dry eye disease (DED), we analyzed trends in Internet search traffic for alternative DED therapies and eye drop safety concerns following initial recalls. METHODS: Google Trends (GT) was used to measure the popularity of specific search terms during a given time period. The main GT output metric for gauging interest in a search term is the Search Volume Index (SVI). We collected worldwide SVI data for terms "dry eye vitamin," "are eye drops safe," "stop eye drops," "lipiflow," "ilux treatment," "dry eye mask," "dry eye warm compress," "omega-3 for dry eyes," "dry eye plugs," "dry eye humidifier," "itear," and "IPL dry eye" from April 24, 2022, to October 29, 2023. Statistical analysis was performed with Microsoft Excel v.16.77.1, and comparisons between groups were performed using paired t tests. RESULTS: A significant increase in SVI was observed for most keywords. When comparing the 40-week period before and after the initial recall, 7/10 alternative DED therapies demonstrated a statistically significant surge in Internet search traffic after recall (P < 0.05). Furthermore, 2/2 keywords pertaining to eye drop safety concerns demonstrated an increase in SVI (P < 0.0001). CONCLUSIONS: We identified a significant surge in Internet search activity for eye drop safety and alternative DED therapies following eye drop recalls. Public health agencies and physicians may find this information valuable while attempting to address safety concerns and navigating noncompliance of routine eye drop therapy.
