In 5 wk alphaA/BKO lenses (Figure 3C), a greater variation in cross sectional diameter was observed, with cell diameters ranging from less than 2 microns up to approximately 25 microns, compared to the 5 wk and 46 wk wild type lenses, whose diameters ranged from less than 2 microns up to approximately 10 microns (Figure 3M and 3R).
