Outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive outcomes, defocus curves, subjective DOF, spectacle independence, and Visual Function questionnaire (VF-14) after 3 months postoperatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Postoperatively, 70% of the Post-LASIK and 86.7% of the Virgin group had refractive error within \u00b1 0.50 D (<jats:italic>P<\/jats:italic> = 0.28). The majority of both groups achieved 20\/25 or better UDVA, with no significant differences between groups for UDVA, CDVA and UIVA (<jats:italic>P<\/jats:italic> &amp;gt; 0.05). The UNVA was significantly better in the Post-LASIK group (0.31 \u00b1 0.08 logMAR) than Virgin group (0.45 \u00b1 0.10 logMAR, <jats:italic>P<\/jats:italic> &amp;lt; 0.001). The Post-LASIK group showed a smoother curve with a wider landing area, and better subjective DOF compared to the Virgin group (<jats:italic>P<\/jats:italic> &amp;lt; 0.001). Spectacle independence at near ranges in bright light was higher in the Post-LASIK group (81.3 % vs 48 %, <jats:italic>P<\/jats:italic> = 0.033).
