Abstract

Purpose: The aim of the study was to evaluate the clinical results of the implantation of the toric intraocular lens Acrysof IQ Toric SN6AT3_8 (Alcon Laboratories, Inc., Fort Worth, TX, USA), including an evaluation of its rotational stability.

Material and methods: 30 eyes of 16 patients (4 males, 12 females; mean age 68 years) with regular corneal astigmatism ranging from -1.5 to -4.0 Dcyl were included in this retrospective study. All the patients underwent uncomplicated cataract surgery with the implantation of a toric intraocular lens (TIOL) at the Department of Ophthalmology of the Faculty of Medicine and Dentistry of Palacký University in Olomouc and University Hospital Olomouc during the course of 2020. Follow-up examinations were performed 3-6 months after cataract surgery. We monitored the resulting uncorrected distance visual acuity (UDVA), postoperative refraction, rotational stability of the implanted lens and subjective patient satisfaction.

Results: mean preoperative corneal astigmatism was -2.41 ±0.67 Dcyl. UDVA improved from a mean value of 0.45 ±0.25 (expressed in decimal Snellen optotype values) to 0.91 ±0.16. The spherical equivalent value of 0.41 ±2.92 improved to -0.11 ±0.27 postoperatively. The mean deviation from the planned axis was 4.87 ±4.75. Subjective satisfaction was rated by patients on a scale of 1-5, with a mean score of 1.5.

Conclusion: TIOL implantation is a safe and effective solution for patients with corneal astigmatism and cataract. Our results demonstrate improved UDVA, rotational stability of the TIOL and subjective patient satisfaction with the outcome of the surgery.

包括旋转稳定性在内的散光眼内透镜植入临床效果评估。

目的：该研究旨在评估植入散光人工晶体 Acrysof IQ Toric SN6AT3_8（Alcon Laboratories, Inc.所有患者均于 2020 年期间在奥洛穆茨帕拉茨基大学医学和牙科学院眼科系以及奥洛穆茨大学医院接受了植入散光眼内透镜 (TIOL) 的无并发症白内障手术。随访检查在白内障手术后 3-6 个月进行。结果：术前角膜散光的平均值为-2.41 ±0.67 Dcyl。UDVA 从平均值 0.45 ±0.25（以十进制 Snellen 光学值表示）提高到 0.91 ±0.16。术后，球面等效值从 0.41 ±2.92 降至 -0.11 ±0.27。与计划轴线的平均偏差为 4.87 ± 4.75。患者的主观满意度按 1-5 级评分，平均分为 1.5 分：TIOL植入术是角膜散光和白内障患者安全有效的解决方案。我们的研究结果表明，TIOL 的 UDVA、旋转稳定性和患者对手术效果的主观满意度均有所提高。
