✓. They have ocular astigmatism in both eyes of between 0.75DC and 2.00DC.
✓. They have a spherical component: plano to -7.00DS (based on ocular refraction).
✓. They are expected to be able to be fitted with the study lenses within the power range available.

✕. 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.
