Introduction. Previous cataract surgery studies assumed that first-eye predicted and observed postoperative refractions are equally important for predicting second-eye postoperative refraction. Methods. In a retrospective analysis of 173 patients having bilateral sequential phacoemulsification, multivariable linear regression was used to predict the second-eye postoperative refraction based on refractions predicted by the SRK-T formula for both eyes, the first-eye postoperative refraction, and the difference in IOL selected between eyes. Results. The first-eye observed postoperative refraction was an independent predictor of the second eye postoperative refraction (P < 0.001) and was weighted more heavily than the first-eye predicted refraction. Compared with the SRK-T formula, this model reduced the root-mean-squared (RMS) error of the predicted refraction by 11.3%. Conclusions. The first-eye postoperative refraction is an independent predictor of the second-eye postoperative refraction. The first-eye predicted refraction is less important. These findings may be due to interocular symmetry.
引言。以往的白内障手术研究认为，第一眼预测的和观察到的术后屈光不正对于预测第二眼术后屈光不正同样重要。方法。在一项对173例行双眼顺序性超声乳化白内障吸除术患者的回顾性分析中，采用多变量线性回归，基于SRK-T公式预测的双眼屈光不正、第一眼术后屈光不正以及两眼之间所选人工晶状体的差异，来预测第二眼术后屈光不正。结果。第一眼观察到的术后屈光不正为第二眼术后屈光不正的独立预测因素（P < 0.001），且其权重比第一眼预测的屈光不正更大。与SRK-T公式相比，该模型将预测屈光不正的均方根（RMS）误差降低了11.3%。结论。第一眼术后屈光不正为第二眼术后屈光不正的独立预测因素。第一眼预测的屈光不正重要性较低。这些发现可能归因于两眼间的对称性。
