A Clinical Comparison of Two Multifocal Toric Soft Contact Lenses

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

Inclusion criteria

• They are aged 35 years or over and have capacity to volunteer.
• They understand their rights as a subject and are willing to sign a Statement of Informed Consent.
• They are willing and able to follow the protocol.
• They agree not to participate in other clinical research for the duration of this study.
• They are currently wearing soft contact lenses or have done so within the past 12 months.
• They have a spherical prescription between +10.00 and -10.00DS inclusive, (based on the ocular refraction).
• They have astigmatism of between -0.75 and -5.75DC (based on the ocular refraction) in each eye.
• They have a reading addition component to their spectacle refraction of between +0.75 and +2.50DS.
• They can be satisfactorily fitted with the study lenses.
• They own a wearable pair of spectacles.

Exclusion criteria

• They have an ocular disorder which would normally contraindicate contact lens wear.
• They have a systemic disorder which would normally contra-indicate contact lens wear.
• They are using any topical medications such as eye drops or ointment.
• They have had cataract surgery.
• They have had corneal refractive surgery.
• They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
• They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear.
• They have eye or health conditions including immunosuppressive or infectious diseases 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 other contact lens or care solution clinical trial or research, within two weeks prior to starting this study.
