Refractive and visual outcomes in the manifest topography-guided group three months postoperative. (a) Cumulative distribution of uncorrected distance Snellen visual acuity (UDVA) compared with preoperative best-corrected distance visual acuity (BCVA). Twenty-four (60.0%) and 36 (90.0%) eyes had a UDVA better than 20/16 and 20/20, respectively, at three months after surgery. (b) Scatter plots of attempted versus achieved manifest refraction spherical equivalent (MRSE). (c) Accuracy of MRSE. Thirty-three eyes (82.5%) had MRSE within ±0.75 D of emmetropia at three months after surgery. (d) Cumulative distribution of refractive astigmatism (RA) compared with the preoperative value. Twenty-six (65.0%) and 35 (87.5%) eyes had an RA less than 0.25 D and 0.50 D, respectively, at three months after surgery
