The mean values of high-contrast logMAR visual acuity at far, intermediate (67 cm), and near (40 cm) were \u22120.10, 0.11, and 0.37 for control, 0.04, 0.00, and 0.15 for \u22120.15 \u00b5m, and 0.23, 0.00, and 0.06 for \u22120.30 \u00b5m conditions. The 95% confidence interval ranged from \u00b10.14 to \u00b10.45 logMAR and the middle 50% of the distribution was approximately 0.2 logMAR.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Negative values of spherical aberration extend the depth of focus in different ways depending on each patient.
