Time course of changes in uncorrected (UDVA) and corrected distance visual acuity (CDVA) in eyes with preoperative against-the-rule astigmatism. UDVA (p < 0.001) and CDVA (p < 0.001) showed a significant decline after surgery. UDVA at 5 years (*p = 0.009) and 8 years (**p < 0.001) postoperatively was significantly worse than UDVA at 1 month postoperatively. CDVA at 5 years (†p = 0.003) and 8 years (‡p = 0.002) after surgery was significantly worse than CDVA at 1 month postoperatively. logMAR logarithm of minimum angle of resolution.
