Figure 4. Lysozyme and albumin distribution through balafilcon A. CLSM (confocal laser scanning microscopy) scans were analyzed to locate the fluorescent-conjugated protein on the front surface, within the bulk region, and on the back surface of balafilcon A after one and 14 days of incubation. Lenses were either rinsed in phosphate buffered saline (PBS), soaked overnight in hydrogen peroxide (H2O2) or soaked overnight in a multipurpose solution (MPS) with (MPS-RUB) or without (MPS-NO-RUB) manual lens rubbing. A, B: These panels show the results for HEL (hen egg lysozyme), C, D: These panels show the results for BSA (bovine serum albumin).
