The influence of angle alpha, angle kappa and optical aberra-tions on the visual outcomes after implantation of a high-addition trifocal IOL_2021

The aim of our investigation was to examine the possible correlations between optical aberrations, angle kappa, angle alpha and the visual outcomes following cataract surgery. 56 eyes of 28 patients were implanted with the Liberty 677MY trifocal intraocular lens (IOL). Pre- and postoperative higher order aberrations, coma, astigmatism, angle alpha and angle kappa were registered, along with uncorrected and corrected visual acuities at multiple distances. Visual acuity and contrast sensitivity defocus curves were plotted and the areas under curve were calculated 1 and 3 months postoperatively.

本研究旨在探究光学像差、角kappa、角alpha与白内障手术后的视觉效果之间可能存在的相关性。在28名患者的56只眼中植入了Liberty 677MY三焦点人工晶状体(IOL)。记录了术前和术后的高阶像差、慧差、散光、角alpha和角kappa，以及多个距离下的未矫正和矫正视力。绘制了视力清晰度和对比度灵敏度失焦曲线，并在术后1个月和3个月计算了曲线下面积。
