Evaluation of diagnostic test or technology.
Stage 1 was a prospective study. The sulcus-to-sulcus (STS) distance was measured using ultrasound biomicroscopy (UBM) (Vumax 2), and the distance from iris pigment end to iris pigment end was assessed using a proposed AS-OCT algorithm. Part 2 used retrospective data from patients after implantation of a PC pIOL with the size selected according to AS-OCT (Visante) measurements of the distance from iris pigment end to iris pigment end. The PC pIOL vault was measured by AS-OCT, and adverse events were assessed.
Stage 1 comprised 32 eyes of 32 myopic patients (mean age 28.4 years ± 6.3 [SD]; mean spherical equivalent [SE] -13.11 ± 4.28 diopters [D]). Stage 2 comprised 29 eyes of 16 patients (mean age 27.7 ± 4.7 years; mean SE -16.55 ± 3.65 D). The mean STS distance (12.35 ± 0.47 mm) was similar to the mean distance from iris pigment end to iris pigment end distance (examiner 1: 12.36 ± 0.51 mm; examiner 2: 12.37 ± 0.53 mm). The PC pIOL sized using the new AS-OCT algorithm had a mean vault of 0.53 ± 0.18 mm and did not produce adverse events during the 12-month follow-up. In 16 of 29 eyes, the PC pIOL vault was within an optimum interval (0.35 to 0.70 mm).
The new measurement algorithm can be effectively used for PC pIOL sizing.

使用眼前节光学相干断层扫描（AS - OCT），基于测量虹膜色素端到虹膜色素端的距离，评估可植入式胶原晶状体后房型有晶状体眼人工晶状体（PC pIOL）尺寸确定的临床效果。

诊断试验或技术评估。
第一阶段为前瞻性研究。使用超声生物显微镜（UBM）（Vumax 2）测量睫状沟到睫状沟（STS）的距离，并使用一种提议的AS - OCT算法评估虹膜色素端到虹膜色素端的距离。第二部分使用植入PC pIOL患者的回顾性数据，PC pIOL的尺寸根据AS - OCT（Visante）测量的虹膜色素端到虹膜色素端的距离来选择。通过AS - OCT测量PC pIOL的拱高，并评估不良事件。
第一阶段包括32例近视患者的32只眼（平均年龄28.4岁±6.3[标准差]；平均等效球镜度[SE] - 13.11±4.28屈光度[D]）。第二阶段包括16例患者的29只眼（平均年龄27.7±4.7岁；平均SE - 16.55±3.65 D）。平均STS距离（12.35±0.47 mm）与虹膜色素端到虹膜色素端的平均距离相似（检查者1：12.36±0.51 mm；检查者2：12.37±0.53 mm）。使用新的AS - OCT算法确定尺寸的PC pIOL平均拱高为0.53±0.18 mm，在12个月的随访期间未产生不良事件。在29只眼中的16只眼中，PC pIOL的拱高处于最佳区间（0.35至0.70 mm）。
新的测量算法可有效地用于确定PC pIOL的尺寸。
