Figure 2. HCEC β1 (integrin CD29) 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=3 to 4, * significantly different from cells grown in the absence of lens and PBS-soaked lens (p<0.045), # significantly different from 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.
