有效晶状体位置预测的研究进展

Research progress on prediction of effective lens position

有效晶状体位置(effective lens position,ELP)是指白内障术后人工晶状体(intraocular lens,IOL)的有效位置,对于白内障术后屈光状态的计算尤其重要,如今有许多研究发现了新的ELP预测方法,比如术前晶状体赤道平面预测ELP,沟到沟(angle to angle,ATA)预测ELP,术中前房深度的测量预测ELP,晶状体前后表面深度预测ELP,术前晶状体三维重建预测ELP,甚至基于人工智能方法来预测ELP等。随着研究深入,对ELP的预测方法更加准确,不仅普通的白内障手术效果更加优良,在某些特殊情况下,如睫状沟植入IOL,角膜屈光术后植入IOL,多焦点、散光IOL植入等也有了进一步的探索,在未来,随着测量技术的进步、手术技术的提升以及预测方法的演变,白内障手术会更加精准。

Effective lens position(ELP)refers to the effective position of intraocular lens(IOL)after cataract surgery,which is especially important for the prediction of refractive power in the cataract surgery.Now many studies have found new methods of ELP prediction,such as the ELP prediction from preoperative lens equatorial plane,angle to angle(ATA),intraoperative anterior chamber depth(ACD),lens anterior and posterior surface depth,preoperative lens three-dimensional reconstruction,and even based on artificial intelligence methods to predict ELP.With the deepening of research,the prediction method of ELP is more accurate,not only the effect of ordinary cataract surgery is better,but also there are further explorations in some special cases such as IOL implantation in ciliary sulcus,after corneal refractive surgery and so on.In the future,with the progress of measurement and surgical techniques,and the evolution of prediction methods,cataract surgery will be more accurate.
