  1. * In contrast to Table 3, Table 4 refers to the mean value / standard deviation in the entire population (patients at regular follow-up or prior to possible revision surgery)
  2. ** Literature source does not state unambiguously whether misalignment was calculated from original values with positive and negative signs or from absolute values
  3. n. r.: not reported, CTR: capsular tension ring, mo: months, we: weeks, post-op.: postoperative, Re-OP: revision surgery
