CDVA = corrected distance visual acuity (6 m); D = diopters; CI =
confidence interval; DCIVA = distance-corrected intermediate visual
acuity (at 60 cm); DCNVA = distance-corrected near visual acuity (40
cm); Dif = difference; FPR = first Purkinje reflex; LogMAR = logarithm
of the minimum angle of resolution; PC = pupil center; UDVA =
uncorrected distance visual acuity (6 m); UIVA = uncorrected
intermediate visual acuity (at 60 cm); UNVA = uncorrected near visual
acuity (40 cm)
The uncorrected distance visual acuity, the difference between UDVA and
CDVA and the postoperative refractive cylinder for both groups are shown
in Figure 4 (A, B and D). The accuracy was similar for both groups,
regarding the postoperative spherical equivalent (Figure 4C); in the FPR
group, 100% of the eyes fell in ±0.50D range, compared to 96.7% of the
eyes in the PC group. One eye (3.3%) in the PC group presented with
negative postoperative spherical equivalent in the range of -0.51 to
-1.25D.
