  Purpose

The purpose of this study is to evaluate the use of a multifocal contact lens in people who previously wore contact lenses but discontinued due to age-related, near vision demands.


Condition Intervention
Presbyopia
Device: lotrafilcon B multifocal contact lens
Device: lotrafilcon B single vision contact lens
Other: Over-reader spectacles

Study Type: Interventional
Study Design: Allocation: Randomized

Primary Outcome Measures:
  • Overall Satisfaction With the Lenses [ Time Frame: 1 week of wear ] [ Designated as safety issue: No ]
    Overall satisfaction with the lenses was interpreted by and assessed by the subject as a single, retrospective measurement of one week's wear time. Overall satisfaction with the lenses was recorded on a questionnaire as a numerical rating on a scale of 1 to 100, with 1 being completely dissatisfied, and 100 being excellent, completely satisfied.

Reading glasses worn over single vision contact lenses for near vision work on an as-needed basis
Single vision CL + reading glasses / Multifocal CL
Lotrafilcon B single vision contact lenses (CL) and over-reader spectacles worn first, with lotrafilcon B multifocal contact lenses (CL) worn second. Both contact lens products worn bilaterally on a daily wear basis; over-reader spectacles worn on an as-needed basis.
Device: lotrafilcon B multifocal contact lens
Commercially marketed, silicone hydrogel, multifocal contact lens for daily wear use
Device: lotrafilcon B single vision contact lens
