摘要：Purpose We investigated the refractive outcomes of second-operated eyes whose diopters of intraocular lens (IOL) were selected based on the prediction error (PE) of the first-operated eye in 1-week-delayed sequential bilateral cataract surgery. Methods Medical records of 100 patients who had undergone delayed sequential bilateral cataract surgery with a 1-week interval were reviewed retrospectively. The postoperative subjective refraction was evaluated at 1 week and 1 month after surgery. The refractive error (RE) was determined by comparing postoperative refraction with the intended postoperative refractive target. The PE was determined by comparing postoperative refraction with the predicted postoperative refraction calculated by multiple different formulae (SRK-T, Hoffer Q, and Haigis). When the PE of the first eye was outside the range of ± 0.25 diopters (D) at postoperative 1 week, selection of IOL power was adjusted to reduce the PE of the second eye. Mean numerical and mean absolute errors of RE were calculated. The correlations between PE of the first eye measured at 1 week and PE of the second eye measured at 1 month were analyzed. Results The mean absolute value of RE was decreased on the second operated eye, but was not significant (p > 0.05). The subgroup whose RE of the first eye was > ± 0.5 D at 1 week showed a significantly decreased mean absolute value of RE in the second eye ( p 0.5 D.
