■本研究旨在评估集成了术中像差测定(IA)和两个人工晶状体(IOL)频率公式的多数决策算法的功效。主要目的是比较三个公式的准确性(IA;桑德斯,Retzlaff,和Kraff/理论界(SRK/T);和巴雷特通用II(BUII)),在植入TFNT透镜(Alcon)的眼睛中实现正视。
■共145例患者的145只眼纳入评价。术前数据从IOLMaster700获得,而术中数据从ORASYSTEMTM收集。确认术后3个月视力≥0.8。我们评估屈光预测误差(RPE),这是预测屈光度(PR)和术后主观屈光度之间的差异。该评估旨在利用所实现的算法来确定最佳IOL功率。
■在评估的145只眼睛中,55.9%,78.7%,97.2%的患者术后主观屈光在±0.13屈光度(D)内,±0.25D,和±0.50D,分别。PR±0.25D范围内的眼睛百分比因公式类型而异,值为57%,57%,和54%的IA,BUII,和SRK/T,分别。对于眼轴长度短至中等(AL<26.00mm)的眼睛,RPE±0.25D内的百分比为52%,58%,IA为58%,SRK/T,BUII,分别。相比之下,对于轴向长度长(≥26.00mm)的眼睛,百分比为68%,52%,IA为45%,BUII,和SRK/T,分别。
■提出的结合IA和两个IOL频率公式的多数决策算法可有效减少术后屈光不正。IA对于具有长眼轴长度的眼睛特别有益。这些发现表明该算法具有优化IOL功率选择以改善患者生活质量和临床实践结果的潜力。
UNASSIGNED: This study aimed to evaluate the efficacy of a majority decision algorithm that integrates intraoperative aberrometry (IA) and two intraocular lens (IOL) frequency formulas. The primary objective was to compare the accuracy of three formulas (IA; Sanders, Retzlaff, and Kraff/Theoretical (SRK/T); and Barrett Universal II (BUII)), in achieving emmetropia in eyes implanted with TFNT lenses (Alcon).
UNASSIGNED: A total of 145 eyes of 145 patients were included in the evaluation. Preoperative data were obtained from IOLMaster 700, while intraoperative data were collected from ORA SYSTEMTM. Visual acuity ≥0.8 at the 3-month post-surgery mark was confirmed. We assessed refractive prediction error (RPE), which is the difference between predicted refraction (PR) and postoperative subjective refraction. This evaluation aimed to identify the optimal IOL power with the implemented algorithm.
UNASSIGNED: Among the 145 eyes evaluated, 55.9%, 78.7%, and 97.2% achieved postoperative subjective refraction within ±0.13 Diopters (D), ±0.25 D, and ±0.50 D, respectively. The percentages of eyes within ±0.25 D of PR varied by formula type, with values of 57%, 57%, and 54% for IA, BUII, and SRK/T, respectively. For eyes with short to medium axial length (AL<26.00 mm), the percentages within ±0.25 D of RPE were 52%, 58%, and 58% for IA, SRK/T, and BUII, respectively. In contrast, for eyes with long axial length (≥26.00 mm) the percentages were 68%, 52%, and 45% for IA, BUII, and SRK/T, respectively.
UNASSIGNED: The proposed majority decision algorithm incorporating IA and two IOL frequency formulas was effective in reducing postoperative refractive error. IA was particularly beneficial for eyes with long axial length. These findings suggest the algorithm has potential to optimize IOL power selection to improve quality of life of patients and clinical practice outcomes.
