Influence of the overall intraocular lens diameter on rotational stability.

Purpose: To evaluate the rotational stability of two intraocular lenses (IOLs) of similar design and material but with a difference of 1 mm in overall length. Methods: In this prospective study patients with age-related cataract were included. An IOL with an overall diameter of 12 mm (ACR6 = small-diameter IOL) was compared to an IOL with an overall diameter of 13 mm (IDEA 613 XC = large-diameter IOL). Results: In total, 60 patients were included in this study. Absolute rotation in the small-and large-diameter groups was 4.4 degrees (SD: 4.0; range: 0.3-17.8) and 3.0 degrees (SD: 2.4; range: 0.1-7.8), respectively. The differences between the two IOLs were not found to be statistically significant. Conclusion: The effect of the overall length of an IOL appears to have little impact on early rotation after cataract surgery. (C) 2015 S. Karger AG, Basel
