Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. They understand their rights as a research subject and are willing to sign a Statement of Informed Consent.
3. They are willing and able to follow the protocol.
4. They can attain at least 6/9 in each eye with their spectacle refraction.
5. They have successfully worn contact lenses within six months of starting the study.
6. They can be fitted with toric soft contact lenses to match the available power range.
Exclusion Criteria
2. They have a systemic disorder which would normally contra-indicate contact lens wear.
3. They are using any topical medication such as eye drops or ointment.
4. They are aphakic.
5. They have had corneal refractive surgery.
6. They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
7. They are pregnant or lactating.
8. 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.
9. They have taken part in any other clinical trial or research, within two weeks prior to starting this study.
