Description
Inclusion Criteria:
- They are of legal age (17 years) and capacity to volunteer.
- They understand their rights as a research subject and are willing to sign a Statement of Informed Consent.
- They are willing and able to follow the protocol.
- They would be expected to attain at least 6/9 (20/30) in each eye with the study lenses.
- They are able to wear contact lenses with a back vertex power of -1.00 to -6.00DS.
- They have a maximum of 1.00D of refractive astigmatism (i.e. ≤ 1.00 DC).
- They have successfully worn contact lenses within six months of starting the study.
Exclusion Criteria:
- They have an ocular disorder which would normally contra-indicate contact lens wear.
- They have a systemic disorder which would normally contra-indicate contact lens wear.
- They are using any topical medication such as eye drops or ointment.
- They are aphakic.
- They have had corneal refractive surgery.
- They have any corneal distortion resulting from previous hard or rigid lens wear or has keratoconus.
- They are pregnant or lactating.
- They have grade 2 or greater of any of the following ocular surface signs: corneal oedema, corneal vascularisation, corneal staining, tarsal conjunctival changes or any other abnormality which would normally contraindicate contact lens wear.
- They have any infectious disease (e.g. hepatitis) or any immunosuppressive disease (e.g. HIV).
- They have diabetes.
- They have taken part in any other clinical trial or research, within two weeks prior to starting this study.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Limbal Hyperemia
Time Frame: At 2 weeks and 4 weeks
|
Measures the redness of the limbal region of the eye on a scale of 0 to 100 grade with 0=none and 100=severe.
The analysis is the average grade over all time frames.
|
At 2 weeks and 4 weeks
|
Lens Comfort
Time Frame: At 3,7,10,13,17,21,24, and 27 days
|
Rating of lens comfort by rating agreement to the following statement: "The lenses I am wearing are comfortable." Rating using the following scale: 1=strongly agree, 2=agree, 3=neutral, 4=disagree, 5=strongly disagree. The rating is averaged over all time frames. |
At 3,7,10,13,17,21,24, and 27 days
|
Upper Lid Margin Staining
Time Frame: At 2 weeks and 4 weeks.
|
Measures the trauma to tissue that lines the margin of the inside of the upper eyelid on a 0 to 3 scale, with 0=none to 3=severe.
The analysis is the average grade over all time frames.
|
At 2 weeks and 4 weeks.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Tarsal Roughness
Time Frame: At 2 weeks and 4 weeks
|
Measures the amount of roughness to the tissue of the inside upper and lower eyelid on a scale of 0 to 100 with 0=none and 100=severe.
The analysis is the average grade over all time frames.
|
At 2 weeks and 4 weeks
|
Tarsal Hyperemia
Time Frame: At 2 weeks and 4 weeks.
|
Measures the amount of redness to the tissue of the inside upper and lower eyelid using a 0 to 100 scale with 0=none and 100=severe.
|
At 2 weeks and 4 weeks.
|
Corneal Staining
Time Frame: At 2 weeks and 4 weeks.
|
A measure of corneal abrasion using a 0 to 100 scale with 0=none, 25=micropunctate, 50=macropunctate, 75=coalescence, 100=patch.
The analysis is the average grade over all time frames.
|
At 2 weeks and 4 weeks.
