Brief Summary

The aim of this study is to compare the short-term clinical performance of two toric contact lenses.

Conditions

Astigmatism

Outcome Measures

Primary Outcomes (1)

• Subjective Overall Score

  The primary outcome measure for this study is the subjective overall score on a scale of 0-100. (0 = Extremely poor. Unmanageable. Cannot use lenses. 100 = Excellent. Highly impressed with these lenses overall.)

  At the end of 15 minutes of daily wear

Secondary Outcomes (2)

• Subjective Vision

  At the end of 15 minutes of daily wear

• Subjective Comfort

  At the end of 15 minutes of daily wear

Study Arms (2)

Device: Lens 1 (ocufilcon D)

Lens 2 (somofilcon A)

EXPERIMENTAL

All participants will wear lens 2 for 15 minutes (Period 2).

Device: Lens 2 (somofilcon A)

Interventions

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• 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.

You may not qualify if:

• 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.
