Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Slit Lamp Findings [ Time Frame: Summarized over all follow-up visits through 1 month ]
    Graded Slit lamp findings (epithelial edema, epithelial microcysts, corneal staining, limbal injection, bulbar injection, upper lid tarsal conjunctival abnormalities, corneal neovascularization, and corneal infiltrates) > grade 2 over all follow-up visits, summarizes the worst case over all follow-up visits. Graded 0-4 with 0=none and 4=severe

  2. logMAR Visual Acuity (VA) [ Time Frame: Summarized over all visits, and dispensed visit ]
    Non-inferiority of distance high contrast logMAR lens VA. A negative value indicates improved VA. Lens VA was established for All Study, Dispensed, 2-Week Follow-up Visit, and 1-Month Follow-up Visit

  3. logMAR Visual Acuity (VA) [ Time Frame: 2 week and 1 month follow-up ]
    Non-inferiority of distance high contrast logMAR lens VA. A negative value indicates improved VA. Lens VA was established for All Study, Dispensed, 2-Week Follow-up Visit, and 1-Month Follow-up Visit


Secondary Outcome Measures :
  1. Lens Wettability [ Time Frame: Summarized over all follow-up visits through 1 month ]
    Lens wettability was rated as Grade 4-0. Grade 4 = 100% of anterior surface wettable (optimal); Grade 3 = presence of small (< 0.1 mm), individual, discrete non-wetting areas (slight); Grade 2 = presence of single area of non-wetting between 0.1 mm and 0.5 mm in size (mild); Grade 1 = presence of several areas on non-wetting, each between 0.1 mm and 0.5 mm in size (moderate); Grade 0 = presence of one or more non-wetting areas > 0.5 mm in size (severe). Suboptimal lens wettability was defined as a rating other than Grade 4, ie slight, mild, moderate, or severe ratings. Over All Visits summarizes the worst case over the dispensing and all follow-up visits.

  2. Lens Deposits [ Time Frame: Summarized over all follow-up visits through one month ]
    Degree of lens deposits was assessed as none, light, medium, or heavy. Suboptimal lens deposits were defined as a degree rating of medium or heavy. Measured over all visits through one month

  3. Lens Centration [ Time Frame: Summarized over all follow-up visits through 1 month ]

    Lens centration was assessed as excellent(fully centered), good (slight decentration, no corneal exposure), fair (decentration, intermittent corneal exposure), or poor (incomplete corneal coverage and/or edge lift).

    Suboptimal lens centration was defined as a rating other than excellent.


  4. Lens Movement [ Time Frame: Summarized over all follow-up visits through one month ]
    Lens movement was assessed as adequate, excessive (> 0.6 mm), insufficient (< 0.2 mm), or adherence. Suboptimal lens movement was defined as a rating other than adequate.

  5. Symptoms & Complaints [ Time Frame: Summarized over all follow-up visits through one month ]
    Subject symptoms/complaints were assessed on a scale from 0 to 100, with 0 denoting least favorable symptoms/complaints and 100 being the most favorable score.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects must have clear central corneas and be free of any anterior segment disorders.
  • Subjects must be adapted wearers of soft contact lenses, wear a lens in each eye, and each lens must be of the same manufacture and brand.
  • Subjects must be correctable through spherocylindrical refraction to 32 letters (0.3 logMAR) or better (distance, high contrast) in each eye.
  • Subjects must be of Asian descent.
  • Subjects must require plano or myopic correction and must require contact lens correction from plano to -6.00 D in both eyes.

Exclusion Criteria:

  • Subjects who have any systemic disease affecting ocular health.
  • Subjects using any systemic or topical medications that will, in the Investigator's opinion, affect ocular physiology or lens performance.
  • Subjects with an active ocular disease or are using any ocular medication.
  • Subjects with any "Present" finding during the slit lamp examination that, in the Investigator's judgment, interferes with contact lens wear.
  • Subjects with any scar or neovascularization within the central 4 mm of the cornea. Subjects with minor peripheral corneal scarring (that does not extend into the central area), that in the Investigator's judgment, does not interfere with contact lens wear, are eligible for this study.
  • Subjects who currently wear monovision, multifocal, or toric contact lenses.
  • Subjects who are adapted wearers of 1-Day Acuvue Define daily disposable cosmetic tint contact lenses.
