AB  - AIM: To predict postoperative intraocular lens (IOL) position using the Sirius 
      anterior segment analysis system and investigate the effect of lens position and 
      IOL type on postoperative refraction. METHODS: A total of 97 patients (102 eyes) 
      were enrolled in the final analysis. An anterior segment biometry measurement was 
      performed preoperatively with Sirius and Lenstar. The results of predicted lens 
      position (PLP) and IOL power were automatically calculated by the software used 
      by the instruments. Effective lens position (ELP) was measured manually using 
      Sirius 3mo postoperatively. Pearson's correlation analysis and linear regression 
      analysis were used to determine the correlation of lens position to other 
      parameters. RESULTS: PLP and ELP were positively correlated to axial length (AL; 
      r=0.42, P<0.0001 and r=0.49, P<0.0001, respectively). There was a weak 
      correlation between the peLP (ELP-PLP) and the prediction error of spherical 
      refraction (peSR; r=0.34, P<0.0001). The peLP of Softec HD IOL differed 
      statistically from those of both the TECNIS ZCB00 and Sensor AR40E IOLs. Multiple 
      linear regression was used to obtain the prediction formula: 
      ELP=0.66+0.63x[aqueous depth (AQD)+0.6LT] (r=0.61, P<0.0001), and a new variable 
      (AQD+0.6 LT) was found to have the strongest correlation with ELP. CONCLUSION: 
      The Sirius anterior segment analysis system is helpful to predict ELP, which 
      reduces postoperative refraction error.
