BACKGROUND
To compare accuracy in intraocular lens (IOL) power calculation in eyes undergoing combined cataract and Descemet stripping and automated endothelial keratoplasty (C-DSAEK) surgery of the following formulas: Barrett Universal II, EVO, Haigis, Hoffer Q, Holladay 2, Kane and SRK/T.
METHODS
72 eyes from 72 patients (38 males, (53%)) with a mean age 68.08 ± 8.69 years (from 44 to 88 years old) underwent combined C-DSAEK were included. The IOL powers to implant were calculated with Barrett Universal II formula targeting -1 D refraction. Preoperative and postoperative data were used to obtain the median of absolute prediction errors (MAE) targeting emmetropia with every tested formula.
RESULTS
Means of MAE calculated were +1.45 D for Barrett Universal II, +1.37 D for EVO, +1.48 D for Haigis, +1.38 D for Hoffer Q, +1.37 D for Holladay 2, +1.39 D for Kane and +1.31 D for SRK/T. SRK/T MAE showed major significant (p < 0.01) differences compared to the other formulas.
DISCUSSION
Even if tested formulas are not able to accurately target emmetropia, SRK/T seems to be able to provide closer results in eyes undergoing C-DSAEK.
背景
比较在白内障合并 Descemet 撕囊和自动化内皮角膜移植术（C-DSAEK）手术中以下公式计算人工晶状体（IOL）屈光力的准确性：Barrett Universal II、EVO、Haigis、Hoffer Q、Holladay 2、Kane 和 SRK/T。
方法
72 例（男性 38 例（53%））72 只眼纳入本研究，平均年龄 68.08 ± 8.69 岁（44-88 岁）。使用 Barrett Universal II 公式，目标屈光度为-1D，计算植入的 IOL 屈光力。使用术前和术后数据，计算每种测试公式的中位绝对预测误差（MAE），以获得正视目标。
结果
Barrett Universal II 的 MAE 平均值为+1.45D，EVO 为+1.37D，Haigis 为+1.48D，Hoffer Q 为+1.38D，Holladay 2 为+1.37D，Kane 为+1.39D，SRK/T 为+1.31D。与其他公式相比，SRK/T 的 MAE 差异具有显著统计学意义（p<0.01）。
讨论
即使测试公式不能准确地将屈光度调整为正视，但是 SRK/T 似乎能够为接受 C-DSAEK 的患者提供更接近的结果。
