Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Comparison of on-eye performance of marketed contact lenses to establish compatibility with commercially available lens care products (solutions). The comparison will involve evaluation of ocular health, lens performance on-eye and subjective responses with these lenses when used up to 3 months on a daily wear or extended wear and disposal schedule.
A range of 19 different contact lens brands (O2OPTIX [Trade mark], NIGHT & DAY, DAILIES AquaComfort Plus [Registered trade mark], ACUVUE ADVANCE [Trade mark], ACUVUE OASYS [Trade mark], ACUVUE 2 [Registered trade mark],1-DAY ACUVUE, 1-DAY ACUVUE. MOIST [Trade mark], Biofinity, Proclear, SofLens One Day, Biomedics One Day, Day by Day, Clear 1 Day, Gelflex 1 Day, PureVision [Trade mark], Avaira [Trade mark], AIR OPTIX [Trade mark], Aqua, AIR OPTIX Individual [Registered trade mark]),will each be combined with one of six different contact lens solutions (AOSept Plus, AQuify, ReNu MultiPlus, OPTI-FREE EXPRESS, OPTI-FREE RepleniSH, COMPLETE Multi-Purpose Solution Easy Rub [Trade mark] Formula). Each contact lens/solution combination will be administered to a minimum of 40 subjects who are involved in a trial for a period of 3 months. Within this 3 month period, each subject will be wearing only one contact lens brand and solution combination. There can be up to 50 different contact lens/solution combinations trialled over a 5 year period.

Outcomes
Primary outcome [1] 4448 0
Primary Outcome: To evaluate the on-eye performance and response of marketed contact lenses and contact lens solutions. The primary outcome will be measured by the evaluation of comfort of lenses on-eye and determination of physiological response to contact lens and contact lens solution combinations.
Timepoint [1] 4448 0
At Baseline, 2 weeks, 1 month, 2 months and 3 months of contact lens wear
Secondary outcome [1] 7520 0
Secondary Outcome 1: To evaluate which combinations of marketed contact lenses and contact lens solutions perform best with each other. This is measured by observing ocular variables including redness, corneal and conjunctival staining.
Timepoint [1] 7520 0
At Baseline, 2 weeks, 1 month, 2 months and 3 months of contact lens wear

Eligibility
Key inclusion criteria
Participants enrolled in the trial must:
- be 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;
- be 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;
- have vision correctable to at least 6/12 (20/40) or better in each eye with contact lenses on a standard Bailey-Lovie logMAR distance letter chart (For a person to see 6/12 or better, this person needs to be able to distinguish clearly an object at 6 metres away that the 'average' person can distinguish at 12 metres away, 20/40 is the equivalent measurement in feet);
- may be experienced or inexperienced at wearing contact lenses.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Participants enrolled in the trial must NOT have:
- 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 e.g. diabetes, Graves disease, and auto-immune diseases such as ankylosing spondylitis, multiple sclerosis, Sjögrens syndrome and systemic lupus erythematosis. Conditions such as systemic hypertension and arthritis do not automatically exclude prospective participants;
- A need for concurrent category S3 and above ocular medication up to 12 weeks prior to and during the trial;
- 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 either in an adverse or beneficial manner;
N.B. Systemic antihistamines are allowed on an ‘as needed basis’, provided they are not used prophylactically during the trial;
- Eye surgery within 12 weeks immediately prior to enrolment for this trial;
- Previous corneal refractive surgery;
- Contraindications to contact lens wear;
- Known allergy to ingredients in contact lens solutions;
- Currently enrolled in another clinical trial;
- Participation in a clinical trial within the previous 2 weeks or participation in an ‘inhouse’ clinical trial within the previous 48 hours;
- Be pregnant*
- Allergy or intolerance to topical anaesthetics

The Investigator may, at his/her discretion, exclude anyone else who they believe may not be able to fulfil the study requirements, or if it is believed to be in the participant’s best interests.

*Formal testing of pregnancy is not required. A participant’s verbal report is sufficient.
