Figure 3. HCEC α₃ (integrin CD49c) expression 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. Integrin expression was measured by flow cytometry and is expressed as a percentage relative to cells grown in the absence of a lens. n=4 to 5, ^* significantly different from cells grown in the absence of lens and PBS-soaked lens (p<0.04), ^# significantly different from its respective buffer control soaked lens (p≤0.04). Complete - Complete Moisture Plus; OFX - Opti-Free Express; ReNu - ReNu MultiPlus; Solo -SoloCare Aqua; BBS - borate buffer saline; PBS - phosphate buffer saline.
