ICL植入术后拱高的预测及研究进展

Prediction of vault after implantable collamer lens implantation and its research progress

摘要:

近视被认为是在遗传-环境等因素影响下产生的一种疾病，只能通过矫正手术恢复视力，目前的手术方式有角膜激光手术和有晶状体眼人工晶状体植入手术(PIOL)，其中PIOL具有矫正范围广、可重复手术、对角膜组织损伤小等优点，植入人工晶状体后就可获得较好的视力改善，可植入折叠透镜(ICL)植入术是目前其在临床上最常见的手术方式。植入人工晶状体的后表面中心最高点与晶状体前囊膜表面的垂直距离被称为拱高，如果拱高异常则会带来严重并发症，术前可以通过多项检查来预测术后拱高，截至目前尚无最佳预测方式，本文以拱高为中心，讨论术后拱高的理想范围，手术的安全性及有效性，并对现有预测方式做出分析，为日后的临床研究提供方向。

Abstract:

Myopia is considered to be a disease occurred under the influence of genetic and environmental factors, and it can only be restored by corrective surgeries. The current surgical methods include laser surgeries and phakic intraocular lens(PIOL)implantation, and PIOL has the advantages of wide range of correction, repeatable procession and small damage to corneal tissue. Furthermore, good visual acuity can be achieved after implantation of intraocular lens. Implantable collamer lens(ICL)is the most common surgical method in this group. The vertical distance between the highest point of the posterior central surface of the implanted lens and the anterior surface of the crystalline lens is called vault. It will cause serious complications if the vault turns out to be abnormal. Up to now, there is no optimal prediction method. This research focuses on vault, discusses the ideal range of postoperative vault, the safety and effectiveness of this surgery, and analyzes the existing prediction methods to provide directions for future clinical research.
