Abstract :
Background: Contact lens wear offers convenient vision correction, but dryness and discomfort remain common, affecting ocular health and quality of life. This study aims to assess dryness and discomfort in symptomatic silicone hydrogel lens wearers and evaluate symptom improvement following refitting with new silicone hydrogel lenses.Materials and Methods: Symptomatic participants attended two clinical visits: those wearing habitual contact lenses (Balafilcon A or Lotrafilcon B) during the initial visit and those transitioning to study silicone hydrogel lenses (Samfilcon A) at the first follow-up. Symptoms related to contact lens dryness and discomfort was measured using the Contact lens dry eye questionnaire-8 (CLDEQ-8) during both visits. A thorough examination of the eyes and contact lenses was performed, followed by an assessment of dry eye. Subsequently, all participants were fitted with the study silicone hydrogel lenses and re-evaluated after two-weeks.Results: Sixty participants completed the trial. Participants reported higher CLDEQ-8 scores while wearing their habitual contact lenses compared to when wearing study silicone hydrogel lenses (12.8 ± 2.6 vs. 3.2 ± 2.9, P
