Notes: (A) Preoperative CDVA and postoperative UDVA and CDVA for group 1 (emmetropia). (B) Preoperative CDVA and postoperative UNVA and CDVA for group 2 (mild myopia for monovision). (C) Difference between UDVA and CDVA for group 1 (emmetropia). (D) Change in CDVA for all 97 eyes.
Abbreviations: UNVA, uncorrected near visual acuity; UDVA, uncorrected distance visual acuity; CDVA, corrected distance visual acuity.
Abbreviations: UNVA, uncorrected near visual acuity; UDVA, uncorrected distance visual acuity; CDVA, corrected distance visual acuity.
Notes: (A) Attempted versus achieved SEQ: group 1. (B) Attempted versus achieved SEQ refraction: group 2. (C) SEQ accuracy (all patients). (D) Pre- versus postoperative astigmatism. (E) TIA versus SIA. (F) Refractive astigmatism AE. The blue lines show attempted correction = achieved correction; the green lines show +0.5 and −0.5 from attempted correction; the pink lines show +1 and −1 from attempted correction; the black lines correspond to the linear regression analysis; the linear regression equations are on the gray boxes in the graphs.
Abbreviations: SEQ, spherical equivalent; TIA, target-induced astigmatism; SIA, surgically induced astigmatism; AE, angle of error; D, diopters.
