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

Eligibility
Key inclusion criteria
- • Able to read and comprehend English and give informed consent as demonstrated by
signing a record of informed consent;

- Be at least 18 years old;

- Willing to comply with the wearing and clinical trial visit schedule as directed
by the investigator;

- Have ocular health findings considered to be "normal" and which would not prevent
the participant from safely wearing contact lenses;

- Has vision correctable to at least 6/12 (20/40) or better at distance in each eye
with contact lenses;

- Be experienced at wearing contact lenses.

Can healthy volunteers participate?
Yes
Key exclusion criteria
- • Any pre-existing ocular irritation, injury or condition (including keratoconus and
herpes keratitis) of the cornea, conjunctiva or eyelids that would preclude contact
lens fitting and safe wearing of contact lenses;

- Any systemic disease that adversely affects ocular health

- An active corneal infection or any active ocular disease that would affect
wearing of contact lenses;

- Use of any topical ocular medication during trial with the exception of saline
drops ;

- Use of or a need for any systemic medication or topical medications which may
alter normal ocular findings/are known to affect a participant's ocular
health/physiology or contact lens performance

- Eye surgery within 12 weeks immediately prior to enrolment for this trial;

- Previous corneal refractive surgery;

- Contraindications to contact lens wear;

- Participated or currently enrolled in another clinical trial that may have
affected vision or ocular physiology within the previous 2 weeks;

- Be pregnant (formal testing of pregnancy is not required. A participant's verbal
report is sufficient);

- Worn soft contact lenses 2 calendar days or rigid gas permeable/ orthokeratology
lenses 7 calendar days prior.
