Descrição
Inclusion Criteria:
- Be between 40 and 65 years of age (inclusive)
- Require a reading addition of +1.25 to +2.50D (inclusive)
- Spherical distance CL or spectacle prescription between +3.00D and -5.00D(inclusive)
- Spectacle cylinder less than or equal to 0.75D in both eyes.
- Currently has a reading add correction in their spectacle or CL habitual correction (e.g. if myope, removes distance correction to read)
- Normal binocularity (no amblyopia, no strabismus, no habitually uncorrected anisometropia ≥ 2.00D)
- Have a minimum 2 weeks soft contact lens experience
- Be able to wear the study lens (e.g. good fit is attained and acceptable subjective comfort and vision for the duration of the study)
- Able to read, comprehend and sign an informed consent
- Willing to comply with the wear and study visit schedule
- Monocular best-corrected distance visual acuity ≥ 20/25 in each eye
- No gas permeable contact lens wear for 1 month prior to the study
Exclusion Criteria:
To be eligible for the study, each candidate must not present with any of the following
- Any active corneal infection, injury, inflammation, or ocular abnormality
- Systemic or ocular allergies, which might interfere with contact lens wear
- Systemic disease, which might interfere with contact lens wear
- Ocular disease, which might interfere with contact lens wear
- Pregnant or lactating
- Strabismus/amblyopia
- Habitually uncorrected anisometropia greater than or equal to 2.00 D
- Subjects who have undergone corneal refractive surgery
- Subjects with keratoconus or other severe corneal irregularity contraindicating lens wear

Comparador Ativo: omafilcon A / PC 1-D MF
omafilcon A (PC 1-D MF) / lotrafilcon B (AIR OPTIX MF) Subjects were randomly assigned into either the omafilcon A/PC 1-D MF lenses with +0.75D over-correction in the non-dominant eye or the lotrafilcon B/Air Optix MF lenses then crossed-over into the alternative pair of study lenses. |

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Objective Vision Assessments: High Contrast Distance Visual Acuity
Prazo: After 1 hour of lens wear
|
Tested with charts distant to the subject with both eyes together in normal lighting conditions.
The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity.
Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.
|
After 1 hour of lens wear
|
|
Objective Vision Assessments: High Contrast Intermediate Visual Acuity
Prazo: After 1 hour of lens wear
|
Tested with charts at intermediate distance (100cm)distant to the subject with both eyes together in normal lighting conditions.
The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity.
Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.
|
After 1 hour of lens wear
|
|
Objective Vision Assessments: High Contrast Near Visual Acuity
Prazo: After 1 hour of lens wear
|
Tested with charts set at near point (40cm)distant to the subject with both eyes together in normal lighting conditions.
The unit of measure is logMAR units (logarithm of the minimum angle of resolution) A logMAR acuity of 0.0 equates to 20/20 Snellen acuity.
Positive logMAR values indicate poorer vision and negative values denote better visual acuity than baseline 20/20 value.
