截至2021年，中国已进行超过280万例小切口拔牙（SMILE）手术。然而，关于SMILE术后白内障患者选择人工透镜（IOL）屈光度计算公式的知识仍然有限。本研究纳入了来自中国北方的26名近视患者的52只眼，这些患者于2022年9月至2023年2月在天津眼科医院接受了SMILE手术，以使用理论手术模型研究多种IOL计算公式在SMILE术后患者中的适用性。我们比较了美国白内障和屈光手术学会（ASCRS）提供的三种基于人工智能（AI）的公式和六种传统公式的术后结果。使用总角膜曲率（TK）和角膜曲率（K）值，应用这些公式计算IOL屈光度，并将结果与从Barrett Universal II（BUII）公式获得的SMILE患者术前结果进行比较。在评价的公式中，从具有TK的正视眼矫正光学2.0公式（EVO-TK）获得的结果（0.40 ± 0.29 D，范围0-1.23 D），Barrett True K（含K公式）（BTK-K，0.41 ± 0.26 D，范围0.01-1.19 D）和K公式的Masket（Masket-K，0.44 ± 0.33 D，范围0.02-1.39 D）显示最接近BUII。值得注意的是，BTK-K（71.15%）、EVO-TK（69.23%）和Masket-K（67.31%）的预测误差在0.5 D内的比例最高，BTK-K的比例显著高于Masket-K（p < 0.001）。我们的研究表明，在SMILE后患者中，EVO-TK，BTK-K和Masket-K可能会产生更准确的计算结果。在目前的发展阶段，基于人工智能的配方并没有表现出比传统配方更大的优势。然而，历史数据的应用可以增强这些公式的性能。
As of 2021, over 2.8 million small-incision lenticule extraction (SMILE) procedures have been performed in China. However, knowledge regarding the selection of intraocular lens (IOL) power calculation formula for post-SMILE cataract patients remains limited. This study included 52 eyes of 26 myopic patients from northern China who underwent SMILE at Tianjin Eye Hospital from September 2022 to February 2023 to investigate the suitability of multiple IOL calculation formulas in post-SMILE patients using a theoretical surgical model. We compared the postoperative results obtained from three artificial intelligence (AI)-based formulas and six conventional formulas provided by the American Society of Cataract and Refractive Surgery (ASCRS). These formulas were applied to calculate IOL power using both total keratometry (TK) and keratometry (K) values, and the results were compared to the preoperative results obtained from the Barrett Universal II (BUII) formula for the SMILE patients. Among the evaluated formulas, the results obtained from the Emmetropia Verifying Optical 2.0 Formula with TK (EVO-TK) (0.40 ± 0.29 D, range 0–1.23 D), Barrett True K with K formula (BTK-K, 0.41 ± 0.26 D, range 0.01–1.19 D), and Masket with K formula (Masket-K, 0.44 ± 0.33 D, range 0.02–1.39 D) demonstrated the closest proximity to BUII. Notably, the highest proportion of prediction errors within 0.5 D was observed with the BTK-K (71.15%), EVO-TK (69.23%), and Masket-K (67.31%), with the BTK-K showing a significantly higher proportion than the Masket-K (p < 0.001). Our research indicates that in post-SMILE patients, the EVO-TK, BTK-K, and Masket-K may yield more accurate calculation results. At their current stage in development, AI-based formulas do not demonstrate significant advantages over conventional formulas. However, the application of historical data can enhance the performance of these formulas.
