1 Scanning Electron Microscopy (SEM) images of rabbit corneas after wearing Bausch & Lomb PureVision® contact lenses for two hours that were soaked overnight in OPTI-FREE Express or Bausch & Lomb ReNu MultiPlus Multi-Purpose Solution.
2 Fresh bovine corneas were stained with a combination of the cell-permeable mitochondria and nuclear-specific dyes rhodamine 123 and Hoechest 33342 or acridine orange and imaged with a Confocal Laser Scanning Microscope (CLSM). High-resolution X-Y images of corneal epithelium were taken using a Zeiss 510 CLSM at 0.44-062 μm Z step and 3-D images of the entire thickness of corneal epithelium were reconstructed. Semi-automated quantitative MatLab software analysis was applied to count the mitochondria in each optical slide. Corneas were treated for 30 minutes with OPTI-FREE Express and ReNu MultiPlus Solution and were investigated and compared to HBSS control.
