title: Influence of the overall intraocular lens diameter on rotational stability.
abstract: OBJECTIVE
  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° (SD: 4.0; range: 0.3-17.8) and 3.0° (SD: 2.4; range: 0.1-7.8), respectively. The differences between the two IOLs were not found to be statistically significant.
  
  
  CONCLUSIONS
  The effect of the overall length of an IOL appears to have little impact on early rotation after cataract surgery.
