COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised to wear either lotrafilcon A silicone hydrogel contact lenses on a daily wear basis for up to 10 days OR comfilcon A silicone hydrogel contact lenses on a daily wear basis flor up to 10 days and then, following a washout period of 7 days where no lenses are worn, crossed over to the other lens group.
Hydrogen peroxide disinfection system (AOSept or Omnicare) will be used for disinfection after each day of wear.

Summary
Brief summary
This project aims to deepen our understanding of the causes of discomfort during contact lens wear. Participants will wear two types of contact lenses (lotrafilcon and comfilcon) for up to 10 days at a time.The project hypothesises that there is a link between the saltiness of peoples' tears, of their contact lenses and the presence of superficial damage to the portion of the upper eyelid that wipes over the contact lens and the sensation of discomfort during lens wear.
