Narrative Responses:

Purpose
To investigate the component of the higher-order aberrations (HOAs) related with the increased near visual acuity in the eyes implanted with aberration-free monofocal intraocular lenses (IOLs).

Methods
All patients underwent phacoemulsification followed by aberration-free monofocal IOL (Envista MX-60, Bausch & Lomb) implantation in the capsular bag. The distance corrected near visual acuity (DCNVA), corrected and uncorrected near and distance visual acuity, defocus curve and HOAs were examined at postoperative 1-month. HOAs were measured using OPD-Scan III (Nidek, Japan). All near visual acuity were examined with a 4 mm external aperture after pharmacologic pupil dilation. We compared the HOAs between the two groups in which DCNVA are better than 0.4 (Group I) and less than 0.25 (Group II) in decimal form (unpaired t-test).

Results
Forty eyes from 40 patients were included. The mean total HOAs were not significantly different between two groups. Vertical coma and spherical aberration were significantly different between two groups.

Conclusion
Negative vertical coma and spherical aberration were related with increased depth of focus in the eyes implanted with aberration-free monofocal IOLs.
