Figure 1 Comparison of contrast sensitivity between Allegretto and visx laser platforms at 3, 6, 12, and 18 cycles per degree (cpd) preoperatively (n = 21) and at 3 months postoperatively (n = 21) using the Vectorvision CSV-1000E chart.

Figure 2 Comparison of higher-order aberrations before surgery (n = 20) and 3 months postoperatively (n = 20) in the wavefront optimized platform. Total, coma, Z(3, 1), trefoil, Z(3, 3), and spherical aberration, Z(4, 0) were measured using the Wavescan at a mean diameter of 6 mm. RMS HOA = root-mean-square higher-order aberration

Figure 3 Comparison of higher-order aberrations before surgery (n = 20) and 3 months postoperatively (n = 20) in the wavefront-guided platform. Total, coma, Z(3, 1), trefoil, Z(3, 3), and spherical aberration, Z(4, 0) were measured using the Wavescan at a mean diameter of 6 mm. (p ≥ 0.126). RMS HOA = root-mean-square higher order aberration.
