摘要
可植入式人工晶状体(ICL)植入术因其良好的近视矫治效果而广泛开展并日趋成熟.术后ICL位置的变化会导致视力下降、并发白内障、青光眼等并发症.本文依据ICL型号、测量参数、ICL周边组织形态、ICL固定位置等从拱高和旋转2个方面总结造成ICL稳定性改变的影响因素及预测参数,发现型号选择参数、眼内空间组织参数、晶状体脚襻位置、生理调节等因素均可能影响ICL/散光型ICL的拱高和轴位.对这些因素的正确判断可为规范ICL手术、提高ICL眼内稳定性、减少并发症提供参考,也是ICL手术精确性及可预测性提高的发展趋势.
Abstract
Implantable collamer lens(ICL)is widely used because of its good effect of myopia correction.The change of ICL position after surgery increases the risk of postoperative complications such as vision loss,complications,and glaucoma.This article summarizes the influencing factors and predictive parameters of ICL position change from two aspects of arch height and rotation according to ICL type,measurement parameters,the shape of the surrounding tissue of ICL,and the fixed position of ICL and found that type selection parameters,the parameter change of intraocular spatial tissue,the position of the lens foot loop,physiological adjustment and other factors can affect the arch height and axial position of ICL/toric ICL.Correct assessment of these factors can provide references for standardizing ICL operation,improving ICL stability,and reducing complications.It is also a trend to improve the accuracy and predictability of ICL surgery.
