目的：测量使用毛果芸香碱后，由睫状肌收缩引起的可调节板触觉型人工晶状体 (IOL) 沿视轴的移动。地点：奥地利维也纳维也纳医科大学眼科。方法：这项前瞻性研究包括 28 名年龄相关性白内障患者的 54 只眼睛。每位患者在标准化白内障手术后均接受了 AT-45 硅胶可调节 IOL（Crystalens，Eyeonics Corp.）。在一个由 24 只眼睛组成的亚组中，通过使用狭缝套管对前囊进行广泛抛光，减少了囊袋纤维化。评估包括使用部分相干干涉测量法测量前房深度，在应用2%毛果芸香碱前后进行评估，并评估术后1个月和3个月的近视力。 结果：未抛光组中IOL轻微向后移动151μm（P）
Purpose: To measure the shift of an accommodating plate-haptic intraocular lens (IOL) along the visual axis induced by ciliary muscle contraction after application of pilocarpine.Setting: Department of Ophthalmology, Medical University of Vienna, Vienna, Austria.Methods: Fifty-four eyes of 28 patients with age-related cataract comprised this prospective study. Each patient received an AT-45 silicone accommodating IOL (Crystalens, Eyeonics Corp.) after standardized cataract surgery. In a subgroup of 24 eyes, capsular bag fibrosis was reduced by extensive polishing of the anterior capsule with a slit cannula. Assessment included measurements of anterior chamber depth, assessed with partial coherence interferometry, before and after application of pilocarpine 2% and evaluation of near visual acuity 1 month and 3 months postoperatively.Results: A slight backward shift of the IOL of 151 mu m in the nonpolished group (P
