Brief Summary

The study objective was to gather short-term clinical performance data for two soft toric contact lenses.

Conditions

Astigmatism

Outcome Measures

Primary Outcomes (1)

• Subjective Overall Score

  The subjective overall impression of the contact lens (scored as a single value per participant) was assessed using a 0-100 visual analogue scale where 0=Extremely poor, 100=Excellent.

  15 minutes

Secondary Outcomes (2)

• Subjective Comfort

  15 minutes

• Subjective Vision

  15 minutes

Study Arms (2)

Lens 1

EXPERIMENTAL

All participants wore Lens 1 for 15 minutes (Period 1)

Device: Lens 1 (omafilcon B)

Lens 2

EXPERIMENTAL

All participants wore Lens 2 for 15 minutes (Period 2)

Device: Lens 2 (fanfilcon A)

Interventions

Lens 1 (omafilcon B) DEVICE

Toric daily wear contact lens for 15 minutes

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 (18) 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 3.00DC.
• 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 lactating.
• 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.
