预留人工晶体度数的选择在白内障手术中的研究进展

Research Progress in the Selection of Reserved IOL in Cataract Surgery

白内障的摘除结合人工晶体植入是目前治愈白内障的唯一手术方法。由于白内障手术朝着屈光手术的发展趋势,病人不但需要再看的见,也同时对视力有了更高的需求,而影响术后视力改善的首要原因便是对人工晶体度数的选择。人工晶体度数的计算主要是通过眼球生物测量的数据结合人工晶体度数计算公式的选择,而眼球生物测量的准确性是白内障手术后视力提高,保证视觉质量的关键因素。白内障手术的眼球生物测量主要包括眼轴长度、角膜曲率、前房深度等。本文就这几个方面的测量方法、进展及优缺点进行综述。

At present, cataract extraction combined with IOL implantation is the only surgical method to cure cataract. Due to the development trend of cataract surgery toward refractive surgery, patients not only need to see again, but also have a higher demand for vision, and the primary reason affecting postoperative vision improvement is the choice of IOL degree. Intraocular lens power calculation is mainly through the measured data of eyeball creature in combination with the choice of intraocular lens power calculation formula, and biological vision after cataract surgery is to improve the accuracy of measurement, a key factor to ensure the quality of vision. Cataract surgery of eye biological measurement mainly includes the ocular axial length corneal curvature anterior chamber depth, etc. In this paper, the measuring method of these a few respects, the progress and advantages and disadvantages are reviewed.
