Figure 1. HCEC viability after 24 h contact with Lotrafilcon A (LA), Balafilcon A (BA), Lotrafilcon B (LB), Galyfilcon A (GA), and Comfilcon
A (CA) lenses soaked in various MPS. Viability was measured by MTT assay and is expressed as a percentage relative to cells
grown in the absence of lenses. n=4 to 5, * significantly different from cells grown in the absence of lens and PBS-soaked lens (p<0.045). & significantly different from cells grown in the absence of lens only (p≤0.01). Complete - Complete Moisture Plus; OFX - Opti-Free
