  1. Values are presented as mean ± standard deviation. Mean absolute neck angle was calculated as the absolute value of the average of neck angles in CCC, phacoemulsification, IOL placement.
  2. LogMAR, logarithm of the minimum angle of resolution; BCVA, best corrected visual acuity; CCC, continuous curvilinear capsulorhexis; IOL, intraocular lens; VAS, visual analog scale; Positive values in neck angle indicate neck flexion, negative values indicate neck extension; *, statistically significant.
