Toric intraocular lenses (IOLs) have been developed to enhance visual acuity impaired by cataracts and correct corneal astigmatism. However, residual astigmatism caused by postoperative rotation of the toric IOL is an important factor affecting visual quality after implantation. To decrease the rotation of the toric IOL, significant advancements have been made in understanding the characteristics of toric IOL rotation, the factors influencing its postoperative rotation, as well as the development of various measurement techniques and interventions to address this issue. It has been established that factors such as the patient's preoperative refractive status, biological parameters, surgical techniques, postoperative care, and long-term management significantly impact the rotational stability of the toric IOL. Clinicians should adopt a personalized approach that considers these factors to minimize the risk of toric IOL rotation and ensure optimal outcomes for each patient. This article reviews the influence of various factors on toric IOL rotational stability. It discusses new challenges that may be encountered to reduce and intervene with rotation after toric IOL implantation in the foreseeable future.
环曲面人工晶状体（IOL）已被研发出来，以提高因白内障而受损的视力，并矫正角膜散光。然而，环曲面IOL术后旋转引起的残余散光，是影响植入后视觉质量的一个重要因素。为了减少环曲面IOL的旋转，在了解环曲面IOL旋转的特征、影响其术后旋转的因素，以及开发各种测量技术和干预措施以解决这一问题方面，已经取得了重大进展。已经确定，患者的术前屈光状态、生物学参数、手术技术、术后护理和长期管理等因素，会显著影响环曲面IOL的旋转稳定性。临床医生应采用个性化方法，考虑这些因素，以将环曲面IOL旋转的风险降至最低，并确保每个患者都能获得最佳效果。本文综述了各种因素对环曲面IOL旋转稳定性的影响。它讨论了在可预见的未来，在环曲面IOL植入后减少和干预旋转可能遇到的新挑战。
