摘要
前房是人眼中由前方角膜与后方虹膜及瞳孔区晶状体组成的空间,也是眼前节最具研究价值的参数之一,与多种眼病的发生、转归和治疗密切相关。白内障术前正确地评估与应用前房深度有利于术后达到最佳视觉质量。人工晶状体有效位置是近几年为了更好地表达人工晶状体植入术后的人工晶状体位置而被提出的术语,为了更充分地理解前房深度和人工晶状体有效位置,文章分别阐述了两者的定义和联系,列举了前房深度的术前测量方式并对比了不同仪器的适用场景,此外进一步总结了其在人工晶状体度数计算及人工晶状体有效位置预测方面的应用,并推荐了如Kane公式等前房深度特殊时预测性更优的晶状体计算公式,探讨了特殊前房深度对白内障术后视觉质量的影响及术中的相关干预措施,以期为临床工作提供一定的参考价值。
The anterior chamber(AC),a space bounded anteriorly by the cornea and posteriorly by the iris and the lens in the pupillary zone,is one of the most significant parameters in the anterior segment of the eye clinically.It is closely associated with the pathogenesis,progression,and treatment of various ocular diseases.Accurate preoperative assessment and utilization of anterior chamber depth(ACD)before surgery are crucial for achieving optimal postoperative visual outcomes.The term,effective lens position(ELP),has been introduced in recent years to better describe the postoperative position of the intraocular lens(IOL).To enhance the comprehension of ACD and ELP,this review elaborates on their definitions and interrelationship.It enumerates preoperative ACD measurement methodologies and compares the applicability of different devices.Furthermore,the review synthesizes its application on IOL power calculation and ELP prediction,recommending optimized formulas such as the Kane formula for scenarios with atypical ACD.The discussion extends to the impact of abnormal ACD on postoperative visual quality and relevant intraoperative interventions,aiming to provide evidence-based references for clinical practice.
