For statistical analysis of visual acuity, logarithm of minimum angle of resolution (logMAR) acuity values were used. Similarly, the recorded contrast sensitivity values were transformed into log values as described by Vector Vision. All data analyses were performed using SPSSX statistical programs (SPSS Inc, Chicago, IL). The 2 IOLs were compared between eyes intraindividually. The analysis was based on a non-normal distribution of the data. The nonparametric Mann-Whitney U test was used to compare data between the 2 IOL groups. A P value less than 0.05 was considered statistically significant.
