The aim of our study was to evaluate the outcome of cataract surgeries with implantation of intraocular trifocal toric lens, and to study the accuracy of astigmatism correction, lens rotational stability, and safety of the procedures.
Our study comprised 22 eyes of 16 patients who underwent unilateral or bilateral implantation of AT LISA tri toric 939MP, or its implantation in combination with AT LISA tri 839MP. Mean patient age was 58 ± 11 years (39 to 75 years). Mean follow-up was 5 months. Evaluated parameters were preoperative and postoperative decimal corrected (CDVA) and uncorrected (UDVA) distance visual acuity. Uncorrected near (UNVA) and intermediate (UIVA) visual acuity was obtained with Jaeger optotypes. Furthermore, we studied manifest refraction, amount of corneal astigmatism, implanted lens position, and potential complications. Using two types of questionnaires we surveyed patients on their subjective satisfaction with vision.
Spherical equivalent changed from preoperative -1.32 ± 4.05 D (-9.25 to 4.00 D) to postoperative -0.23 ± 0.21 D (-0.75 to 0.00 D). Preoperative corneal astigmatism was -1.97 ± 0.76 D (-4.02 to -1.01 D), manifest astigmatism was -1.70 ± 1.26 D. After the surgery, manifest astigmatism significantly improved to -0.34 ± 0.37 D (p<0.001). Mean monocular UDVA increased from 0.26 ± 0.18 (0.05 to 0.60) to postoperative 0.88 ± 0.13 (0.60 to 1.00) (p<0.001). CDVA also improved significantly, from 0.57 ± 0.24 to a final value of 1.02 ± 0.07 (p<0.001). Mean postoperative monocular UNVA was Jaeger 1-2, UIVA corresponded to Jaeger 3-4.No serious complications were recorded. Based on the outcome of questionnaires, all patients are satisfied with their vision and they are independent of spectacles.
In the present study we have obtained very good functional outcomes of vision at far, near and intermediate in cataract patients after trifocal AT LISA tri toric lens implantation. Also, total astigmatism in studied eyes was substantially reduced. The treatment led to a high subjective satisfaction of patients and to their independence of spectacles.

本研究旨在评估植入眼内三焦点环曲面人工晶状体的白内障手术效果，并研究散光矫正的准确性、晶状体旋转稳定性以及手术的安全性。
本研究纳入了16例患者的22只眼，这些患者接受了单侧或双侧AT LISA tri toric 939MP人工晶状体植入，或其与AT LISA tri 839MP联合植入。患者平均年龄为58±11岁（39至75岁）。平均随访时间为5个月。评估参数包括术前和术后小数矫正（CDVA）及未矫正（UDVA）远视力。使用耶格视力表获得未矫正近视力（UNVA）和中视力（UIVA）。此外，我们研究了显验光、角膜散光量、植入晶状体位置以及潜在并发症。我们使用两种问卷对患者的视力主观满意度进行了调查。
等效球镜度从术前的-1.32±4.05 D（-9.25至4.00 D）变为术后的-0.23±0.21 D（-0.75至0.00 D）。术前角膜散光为-1.97±0.76 D（-4.02至-1.01 D），显散光为-1.70±1.26 D。手术后，显散光显著改善至-0.34±0.37 D（p<0.001）。平均单眼UDVA从术前的0.26±0.18（0.05至0.60）提高到术后的0.88±0.13（0.60至1.00）（p<0.001）。CDVA也显著改善，从0.57±0.24提高到最终值1.02±0.07（p<0.001）。术后平均单眼UNVA为耶格1-2级，UIVA相当于耶格3-4级。未记录到严重并发症。根据问卷结果，所有患者对其视力满意，且无需依赖眼镜。
在本研究中，我们发现白内障患者在植入三焦点AT LISA tri toric人工晶状体后，在远、近和中距离均获得了非常好的视力功能结果。此外，研究眼中的总散光也大幅降低。该治疗使患者获得了较高的主观满意度，且无需依赖眼镜。
