Summary

Contact lens induced dry eyes leads to lens intolerance and discontinuation. Incidence of dry eye in contact lens wearer is significantly higher in Asian population compared to other ethnic group considering Asian has lower tear break up time. Disruptions of tear integrity in contact lens wearer will further exacerbate the condition. Factors for successful contact lens fitting derive from the biocompatibility of lens material, lens design and stability of tear film in front of the contact lens. This study aim to investigate the efficacy of a novel daily disposable contact lens with zwitterionic material that contains alginic acid which act as a moisturizing agent. The improved lens material may likely improve the comfort and treat symptomatic wearers.
