CDVA = corrected distance visual acuity (6 m); D = diopters; FPR = first Purkinje reflex centration; LogMAR = logarithm of the minimum angle of resolution; PC = pupil center centration; SD=standard deviation; UDVA = uncorrected distance visual acuity (6 m). †Lens Opacities Classification System III grade
Postoperative data
As to the postoperative chord mu, there was no statistically significant difference between the two groups (95% CI: -0.004 to 0.017; p=0.182); the same statistical findings regarding postoperative alpha distance were registered (95% CI: 0.000 to 0.00; p=0.067). Nevertheless, a statistically significant difference was found between pre and postoperative chord mu in each group (p<0.001), traducing a shorter distance between PC and FPR after surgery. Furthermore, when comparing the change in chord mu between groups, a statistically significant difference was found (95% CI: -0.026 to -0.002; p=0.022), with a higher change in the PC group (Table 2).
