For cataract patients with astigmatism, the insertion of a toric intraocular lens is a safe and effective method to achieve emmetropia. The exact alignment of the lens along the calculated axis is essential for effective correction of astigmatism. The purpose of this study is to evaluate our own data using descriptive statistics. The primary focus is on the refractive outcome and thus the verification of the alignment accuracy of toric IOLs with the Zeiss Callisto system.
The study evaluated a total of 106 eyes of 72 patients who underwent cataract surgery with implantation of a toric intraocular lens at our hospital between January 2019 and December 2020. Preoperative biometry and intraoperative marking of the implantation axis was performed using the Zeiss Callisto system. Postoperative controls were performed after one day, one week and 4 weeks, either at our hospital or by the referring ophthalmologist. For the analysis, only the data of the 4-week control were used.
In 64 eyes (60%), a Zeiss AT Torbi 709 M or MP and in 42 eyes (40%) a PhysIOL Ankoris toric yellow IOL were implanted. In 46 eyes, postoperative uncorrected visual acuity was not recorded. Of the remaining 60 eyes, the mean postoperative uncorrected visual acuity was 0.07 ± 0.12 logMAR. Postoperative uncorrected visual acuity ≥ 1.0 (decimal) was achieved in 48% of the eyes and visual acuity ≥ 0.6 (decimal) in 92%. The postoperative cylinder averaged - 0.65 ± 0.53 D. The cylinder of the target refraction was - 0.45 ± 0.39 D on average. The mean of the absolute value of the postoperative cylinder minus the cylinder of the target refraction was 0.42 ± 0.32 D.
The Zeiss Callisto system is an effective tool to align toric intraocular lenses.
对于合并散光的白内障患者，植入散光人工晶状体是实现正视化的一种安全有效的方法。晶状体沿计算轴的精确对齐对于有效矫正散光至关重要。本研究的目的是使用描述性统计评估我们自己的数据。主要重点是屈光结果，从而验证蔡司Callisto系统对散光人工晶状体的对齐准确性。
本研究评估了2019年1月至2020年12月期间在我院接受白内障手术并植入散光人工晶状体的72例患者的106只眼。术前使用蔡司Callisto系统进行生物测量并标记植入轴。术后一天、一周和4周在我院或由转诊的眼科医生进行复查。分析时仅使用4周复查的数据。
64只眼（60%）植入了蔡司AT Torbi 709 M或MP人工晶状体，42只眼（40%）植入了PhysIOL Ankoris散光黄色人工晶状体。46只眼未记录术后未矫正视力。其余60只眼中，术后平均未矫正视力为0.07±0.12 logMAR。48%的眼术后未矫正视力≥1.0（小数），92%的眼视力≥0.6（小数）。术后柱镜平均为-0.65±0.53 D。目标屈光的柱镜平均为-0.45±0.39 D。术后柱镜绝对值减去目标屈光柱镜的平均值为0.42±0.32 D。
蔡司Callisto系统是对齐散光人工晶状体的有效工具。
