Fig. 129. Comparison of PCO/Nd:YAG laser rates of different PC-IOL types implanted in patients in the United States. The exact percentages and order noted here are slightly different than seen in Figure 143 because the time of the calculations was several months before the figures accumulated in the analysis of Figure 143.
