Investigating the impact of residual refraction within ±1.0 dioptre on uncorrected distance visual acuity in pseudophakic eyes: a cross-sectional study
The impact of refractive errors (≤1.0 D) on UDVA was associated with the magnitude and type of astigmatism. Residual astigmatism of ≥0.50 D exerted a significant negative effect on UDVA. A plano SE (0 D) was optimal for minimum and WTR astigmatism, whereas slight hyperopia yielded superior UDVA in ATR and oblique astigmatism.
