To compare the accuracy of intraoperative wavefront aberrometry (ORA) and the Hill-radial basis function (RBF) formula with other formulas based on preoperative biometry in predicting residual refractive error after cataract surgery in eyes with axial myopia.
Private practice, Harrisburg, Pennsylvania, USA.
Retrospective consecutive case series.
Eyes with an axial length (AL) greater than 25.0 mm had cataract extraction with intraocular lens implantation. For each eye, the 1-center Wang-Koch AL-optimized Holladay 1 formula was used to select an IOL targeting emmetropia. Residual refractive error was predicted preoperatively using the SRK/T, Holladay 1 and 2, Barrett Universal II, and Hill-RBF formulas and intraoperatively using wavefront aberrometry. The postoperative refraction was compared with the preoperative and intraoperative predictions.
The study comprised 37 patients (51 eyes). The mean numerical errors ± standard error associated with using the SRK/T, Holladay 1, AL-optimized Holladay 1, Holladay 2, Barrett Universal II, and Hill-RBF formulas and intraoperative wavefront aberrometry were 0.20 ± 0.06 diopters (D), 0.33 ± 0.06 D, -0.02 ± 0.06 D, 0.24 ± 0.06 D, 0.19 ± 0.06 D, 0.22 ± 0.06 D, and 0.056 ± 0.06 D, respectively (P < .001). The proportion of patients within ±0.5 D of the predicted error was 74.5%, 62.8%, 82.4%, 79.1%, 73.9%, 76.7%, and 80.4%, respectively (P = .090). Hyperopic outcomes occurred in 70.6%, 76.5%, 49.0%, 74.4%, 76.1%, 74.4%, and 45.1% of the eyes, respectively (P = .007).
Intraoperative wavefront aberrometry was better than all formulas based on preoperative biometry and as effective as the AL-optimized Holladay 1 formula in predicting residual refractive error and reducing hyperopic outcomes. The Hill-RBF formula's performance was similar to that of the fourth-generation formulas.

眼轴（AL）大于 25.0 毫米的患者行白内障超声乳化吸除术联合人工晶状体植入术。对于每只眼，使用 1 中心点 Wang-Koch AL 优化 Holladay 1 公式选择用于矫正正视的人工晶状体。使用 SRK/T、Holladay 1 和 2、Barrett Universal II 和 Hill-RBF 公式在术前预测残余屈光误差，并在术中使用波前像差进行预测。比较术后屈光度与术前和术中预测值的差异。
本研究共纳入 37 名患者（51 只眼）。使用 SRK/T、Holladay 1、AL 优化 Holladay 1、Holladay 2、Barrett Universal II 和 Hill-RBF 公式及术中波前像差预测时，平均数值误差±标准误差分别为 0.20±0.06 屈光度（D）、0.33±0.06 D、-0.02±0.06 D、0.24±0.06 D、0.19±0.06 D、0.22±0.06 D 和 0.056±0.06 D（P<.001）。预测误差在±0.5 D 以内的患者比例分别为 74.5%、62.8%、82.4%、79.1%、73.9%、76.7%和 80.4%（P=.090）。远视眼发生率分别为 70.6%、76.5%、49.0%、74.4%、76.1%、74.4%和 45.1%（P=.007）。
术中波前像差优于所有基于术前生物测量的公式，与 AL 优化 Holladay 1 公式在预测残余屈光误差和减少远视眼发生率方面同样有效。Hill-RBF 公式的性能与第四代公式相似。
