CI = confidence interval; Dif = difference; FPR = first Purkinje reflex;
Mean Dif., mean difference; PC = pupil center; SD, standard deviation.
*Statistically significant.
The mean postoperative IOL center (IOLC) – FPR distance was 0,193±0088
mm in the PC group, whereas it was 0,159±0,068 mm in the FPR group,
representing a statistically significant difference between the two
capsulotomy groups (mean difference: 0.034±0.046 mm; 95% CI: 0.017 to
0.050; p<0.001). Likewise, a statistically significant
difference (mean difference: 0.015±0.025 mm; 95% CI: 0.006 to 0.024;
p<0.01) was also found between groups regarding the IOLC – OC
(optical center of the cornea). Considering IOLC – PC (pupil center)
distance, no statistically significant difference was found between PC
and FPR capsulotomy centration (mean difference: 0.020±0.056 mm; 95%:
0.000 to 0.040; p=0.064) (Table 3). Figure 3 illustrates the difference
in distance from IOL center to FPR between both eyes of the same
patient, with a different capsulotomy centration per eye.
