In the CACG group, 23 eyes (51%) had three\u2010piece IOL implantation and 22 eyes (49%) had one\u2010piece IOL implantation. In the normal control group, 25 eyes (52%) had three\u2010piece IOL implantation and 23 eyes (48%) had one\u2010piece IOL implantation. Using the SRK\/T formula, the mean difference between the predicted and actual postoperative spherical equivalent [mean absolute error (MAE)] was obtained and converted to natural logarithm (ln) for statistical analysis. The power of the implanted IOL was calculated to predict postoperative SE using three formulas: SRK II, Holladay II and Hoffer Q by <jats:italic>post hoc<\/jats:italic> analysis in each group. The predictive accuracy of each formula was analysed by comparing the lnMAE.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> In the one\u2010piece IOL group, there was no difference in lnMAE between the CACG and normal control group (p\u2003=\u20030.314). In the three\u2010piece IOL group, the lnMAE of the CACG group was larger than that of the normal control group (p\u2003&lt;\u20030.001). The lnMAEs calculated by the SRK\/T formula were more accurate than the Holladay II (p\u2003=\u20030.045) and Hoffer Q (p\u2003=\u20030.042) formula in the CACG one\u2010piece IOL group.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> Implantation of one\u2010piece IOLs provides similar power prediction accuracy comparable to normal cataract patients; this result may be explained by the IOL haptic configuration or design.<\/jats:p>","DOI":"10.1111\/j.1755-3768.2012.02499.x","type":"journal-article","created":{"date-parts":[[2012,9,12]],"date-time":"2012-09-12T12:00:03Z","timestamp":1347451203000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Power
