Overview

Cross-sectional study analyzes risk behaviors for infectious keratitis among different contact lens types in Switzerland, suggesting the need for targeted education.

Key Points

  • The aim is to evaluate risk behaviors related to infectious keratitis among Swiss contact lens wearers, focusing on differences by lens type.
  • Cross-sectional survey conducted across five eye care institutions in Switzerland.
  • Participants (N=156) were categorized into four contact lens subgroups: daily disposable, reusable, rigid corneal, and rigid scleral.
  • Data on demographics, lens type, knowledge, and risk behaviors were collected through a structured questionnaire.
  • 24.4% of participants wore daily disposable soft contact lenses, while 30.8% wore reusable, 25.6% rigid corneal, and 19.2% rigid scleral lenses.
  • Users of rigid contact lenses reported better knowledge and exhibited fewer risk behaviors than soft contact lens users.
  • Common risk behaviors included improper lens handling, extended wear, sleeping with lenses, and water exposure across all lens types.
