To evaluate a recently introduced ESCRS online calculator for intraocular lens (IOL) calculation of a multifocal IOL in refractive lens exchange and cataract surgery in a prospective setting.
Department of Ophthalmology, Goethe University Frankfurt, Germany.
Prospective, consecutive case series.
Eyes that received lens extraction and multifocal IOL implantation were included. The mean prediction error, mean absolute error, and median absolute prediction error (MedAE) provided by the ESCRS online calculator were compared, as were the number of eyes within ±0.5 diopters (D), ±1.0 D, ±2.0 D of target refraction. The SRK/T formula was also included for comparison. Postoperative spherical equivalent was measured at 3 months. 1 eye per patient was included.
88 eyes from 88 patients with a mean age of 62 ± 9.5 years were included. The MedAE was low for all formulas and ranged from 0.26 D (Kane), Hill-RBF (0.27 D), Hoffer Q Savini/Taroni (Hoffer QST) (0.27 D), Barrett Universal II (BUII) (0.28 D), Emmetropia Verifying Optical (EVO) (0.29 D), Cooke K6 (0.27 D), 0.30 D (Postoperative spherical Equivalent prediction using Artificial intelligence and Linear algorithms, by Debellemaniére, Gatinel, and Saad [Pearl DGS]) to 0.31 D (SRK/T). No statistically significant difference was found ( P = .627). Considering the number of eyes within ±0.5 D of the calculated refraction the best performing was again the Hill-RBF (84%, 74 eyes), again followed by Kane (71, 81%), EVO, Pearl DGS, Hoffer QST, BUII (each 80%, 70 eyes), Cooke K6 (78%, 69 eyes), and SRK/T (74%). Again, no statistically significant difference was found ( P = .39).
Using a recently introduced ESCRS online IOL calculator in multifocal IOLs leds to a high number of eyes reaching target refraction and low prediction errors. All formulas performed similarly well. Hill-RBF showed the highest number of eyes within ±0.5 D, but no significance was found.
在一项前瞻性研究中，评估最近推出的欧洲白内障与屈光手术医师学会（ESCRS）在线计算器，用于屈光性晶状体置换术和白内障手术中多焦点人工晶状体（IOL）的计算。
德国法兰克福歌德大学眼科。
前瞻性、连续病例系列。
纳入接受晶状体摘除和多焦点IOL植入的眼睛。比较ESCRS在线计算器提供的平均预测误差、平均绝对误差和中位数绝对预测误差（MedAE），以及目标屈光度数±0.5屈光度（D）、±1.0 D、±2.0 D范围内的眼睛数量。还纳入SRK/T公式进行比较。术后3个月测量等效球镜度。每位患者纳入1只眼。
纳入88例患者的88只眼，平均年龄62±9.5岁。所有公式的MedAE都较低，范围从0.26 D（凯恩公式）、希尔径向基函数（Hill-RBF）（0.27 D）、霍弗Q萨维尼/塔罗尼（Hoffer Q Savini/Taroni，Hoffer QST）（0.27 D）、巴雷特通用二代（Barrett Universal II，BUII）（0.28 D）、正视验证光学（Emmetropia Verifying Optical，EVO）（0.29 D）、库克K6（0.27 D）、0.30 D（德贝莱马尼埃、加蒂内尔和萨德[珍珠DGS]使用人工智能和线性算法进行的术后等效球镜度预测）到0.31 D（SRK/T）。未发现统计学显著差异（P = 0.627）。考虑计算屈光度±0.5 D范围内的眼睛数量，表现最佳的仍是Hill-RBF（84%，74只眼），其次是凯恩公式（71只，81%）、EVO、珍珠DGS、Hoffer QST、BUII（均为80%，70只眼）、库克K6（78%，69只眼）和SRK/T（74%）。同样，未发现统计学显著差异（P = 0.39）。
在多焦点IOL中使用最近推出的ESCRS在线IOL计算器，可使大量眼睛达到目标屈光度数且预测误差较低。所有公式的表现都相似。Hill-RBF在±0.5 D范围内的眼睛数量最多，但未发现显著差异。
