Purpose

The objective of this trial is compare the visual performance, ratings, and preference of two multifocal, soft contact lenses.

Condition	Intervention
Presbyopia	Device: Lotrafilcon B Device: Senofilcon A


Study Type:	Interventional
Study Design:	Allocation: Randomized Intervention Model: Crossover Assignment Masking: Single Blind (Participant) Primary Purpose: Treatment
Official Title:	Clinical Evaluation of Two New Silicone Hydrogel Multifocal Products

Primary Outcome Measures:

Corrected Distance Binocular Visual Measurement in Normal Illumination Reported as Binocular Distance Visual Acuity [ Time Frame: After 1 week of wear ]
Tested while reading charts distant to the subject with both eyes together in normal lighting. This outcome is measured in logMAR units (logarithm of the minimum angle of resolution). A logMAR acuity of 0.0 equates to 20/20 Snellen acuity and is considered normal. Positive logMAR values indicate poorer vision and negative values denote better visual acuity.
