A Clinical Comparison of Two Soft Toric Contact Lenses

The aim of this study is to evaluate the short-term clinical performance of two toric contact lenses when compared to each other after 15 minutes of daily wear each.

Inclusion criteria

• They are of legal age and capacity to volunteer.
• They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
• They are willing and able to follow the protocol.
• They currently wear soft contact lenses, or have done so within the past two years.
• 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.

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 have keratoconus.
• They are pregnant or breastfeeding.
• They have an eye or health condition including an immunosuppressive or infectious disease which would, in the opinion of the investigator, contraindicate contact lens wear or pose a risk to study personnel; or a history of anaphylaxis or severe allergic reaction.
• They have taken part in any contact lens or care system clinical research within two weeks prior to starting this study.
