飞秒激光原位角膜磨镶术（FS-LASIK）和小切口晶状体摘除术（SMILE）是中国最流行的两种屈光手术，有相当数量的患者接受过这两种手术。然而，对于这些有FS-LASIK或SMILE病史的患者，关于选择人工透镜（IOL）屈光度计算公式的知识仍然有限。本前瞻性队列研究共纳入了50例术后屈光手术患者的100只眼，其中25例（50只眼）接受了FS-LASIK，25例（50只眼）接受了SMILE。我们利用理论手术模型来模拟术后FS-LASIK和SMILE患者的IOL植入过程。随后，我们在手术前后进行了全面的生物测量，包括人口统计学信息，角膜生物特征参数和眼轴长度。采用各种公式（包括Barrett Universal II（BUII）公式）作为基线计算患者的IOL屈光度。Barrett True K（BTK）公式表明，FS-LASIK和SMILE组的平均绝对误差（AE）均在0.5 D范围内（分别为0.28 ± 0.25 D和0.36 ± 0.24 D）。值得注意的是，与术前BUII结果相比，FS-LASIK组显示82%的结果差异小于0.25 D。Barrett True K无病史（BTKNH）公式也包含测量的后角膜曲率，在两组中的表现与BTK相似。此外，与BTK相比，Masket公式依赖于基于经验的屈光变化，显示出SMILE患者IOL计算的良好潜力（p = 0.411）。该研究揭示了BTK和BTKNH公式用于近视FS-LASIK/SMILE患者IOL屈光度计算的准确性和稳定性。此外，Masket配方在SMILE患者中显示出令人鼓舞的结果。这些发现有助于提高有屈光手术史患者IOL屈光度计算的可预测性和成功率，为临床实践提供有价值的见解。进一步的研究和更大的样本量是必要的，以验证和优化确定的公式，以获得更好的患者结果。
As the two most prevalent refractive surgeries in China, there is a substantial number of patients who have undergone Femtosecond Laser-assisted In Situ Keratomileusis (FS-LASIK) and Small Incision Lenticule Extraction (SMILE) procedures. However, there is still limited knowledge regarding the selection of intraocular lens (IOL) power calculation formulas for these patients with a history of FS-LASIK or SMILE. A total of 100 eyes from 50 postoperative refractive surgery patients were included in this prospective cohort study, with 25 individuals (50 eyes) having undergone FS-LASIK and 25 individuals (50 eyes) having undergone SMILE. We utilized a theoretical surgical model to simulate the IOL implantation process in postoperative FS-LASIK and SMILE patients. Subsequently, we performed comprehensive biological measurements both before and after the surgeries, encompassing demographic information, corneal biometric parameters, and axial length. Various formulas, including the Barrett Universal II (BUII) formula, as a baseline, were employed to calculate IOL power for the patients. The Barrett True K (BTK) formula, demonstrated an mean absolute error (AE) within 0.5 D for both FS-LASIK and SMILE groups (0.28 ± 0.25 D and 0.36 ± 0.24 D, respectively). Notably, the FS-LASIK group showed 82% of results differing by less than 0.25 D compared to preoperative BUII results. The Barrett True K No History (BTKNH) formula, which also incorporates measured posterior corneal curvature, performed similarly to BTK in both groups. Additionally, the Masket formula, relying on refractive changes based on empirical experience, displayed promising potential for IOL calculations in SMILE patients compared with BTK (p = 0.411). The study reveals the accuracy and stability of the BTK and BTKNH formulas for IOL power calculations in myopic FS-LASIK/SMILE patients. Moreover, the Masket formula shows encouraging results in SMILE patients. These findings contribute to enhancing the predictability and success of IOL power calculations in patients with a history of refractive surgery, providing valuable insights for clinical practice. Further research and larger sample sizes are warranted to validate and optimize the identified formulas for better patient outcomes.
