Why carry out this study?

Understanding the nature of postoperative intraocular lens (IOL) shift, refractive change, and margin of error in predicted postoperative refraction (PPR) is crucial for the accuracy of PPR.

We aimed to assess the relationships between different fixation methods of IOLs with different haptic designs and describe the correlation between IOL shift, postoperative refraction, margin of error in PPR, and preoperative biometric variables.

What was learned from the study?

The relationship between the postoperative IOL shift and refraction change varied among IOLs with different haptic designs; preoperative anterior chamber depth, lens thickness, and axial length may have predictive roles.

The study results indicate that capsulorhexis may be more stable than in-the-bag IOL fixation, leading to improved accuracy of PPR and better refractive outcomes.
