The experimental groups in this study are represented by a combination of different in vivo eye treatment conditions (normal, control, treated) and ex vivo strip treatments (FRESH, PBS, GEN). Five of the possible nine combinations of eye and strip treatments were tested (normal FRESH, control FRESH, control PBS, treated PBS, treated GEN). Both strips from normal animal eyes were mechanically tested after enucleation (normal FRESH). Strips of the control eyes of −5D lens treated animals were either tested after enucleation (control FRESH) or after incubation for 24 hours in PBS (control PBS). The strips of the lens treated eyes were tested after 24 incubation hours in PBS (treated PBS) or PBS supplemented with genipin (treated GEN). * Only one eye of each normal animal (randomly chosen between left and right eye) was used in this study.
