本文评估了有助于形成有效的囊弯曲以阻止后囊混浊的因素。其目的是帮助执业眼科医生将目前对这一过程的理解与以前提出的各种工作模型分开。虽然方形边缘设计明显提高了对后囊膜混浊的抵抗力，但重要因素仍在外科医生的控制之下。这些因素联合收割机形成囊弯曲的生理和心理障碍。创新的数字成像显示透镜上皮细胞迁移，允许更快速地评估后囊膜混浊抗性。三件式眼内透镜允许围绕光学边缘形成完整的360度囊弯曲;某些单件式设计可能抑制囊弯曲形成。减少但不消除存活的透镜上皮细胞群可降低囊弯曲强度，这可降低面对再生皮质时对后囊膜混浊的抵抗力。透明/屈光性透镜交换的所有人口统计学特征表明后囊混浊发生率高于标准白内障手术。囊弯曲形成的质量将决定人工透镜对皮质再生导致的后囊混浊的抵抗力。随着屈光性透镜交换和新的可调节人工透镜设计越来越流行，皮层再生的问题将越来越严重。
This paper assesses the factors that contribute to the formation of an effective capsular bend as a deterrent to posterior capsule opacification. Its goal is to assist the practicing ophthalmologist in separating current understanding of this process from various working models previously proposed.While a square-edge design appreciably improves resistance to posterior capsule opacification, significant factors remain under the control of the surgeon. These factors combine to form the physical and psychological barrier of a capsular bend. Innovative digital imaging has shown lens epithelial cell migration, allowing for a more rapid assessment of posterior capsule opacification resistance. A three-piece intraocular lens allows for full 360 degree capsular bend formation surrounding the optic edge; some single-piece designs may inhibit capsular bend formation. Decreasing, but not eliminating, the surviving lens epithelial cell population may diminish capsular bend strength, which may decrease resistance to posterior capsule opacification in the face of a regenerating cortex. All demographic features of clear/refractive lens exchange suggest higher rates of posterior capsule opacification than with standard cataract surgery.The quality of capsular bend formation will determine how resistant an intraocular lens will be to posterior capsule opacification as a consequence of regenerating cortex, As refractive lens exchange and new accommodating intraocular lens designs become more popular, the problems of regenerating cortex will increase in magnitude.
