有晶状体眼人工晶状体植入术矫正高度近视在视觉质量上的优越性

Superiority on visual quality of Phakic intraocular lens implantation in high myopic patients： compared with LASIK

有晶状体眼人工晶状体植入术（PIOL）是一种新的矫正高度近视的手术方法。视觉质量包括视力、对比敏感度（CS）、波前像差及角膜的非球面参数（Q值）等。传统的准分子激光角膜原位磨镶术（LASIK）由于切削改变角膜的非球面性导致术后视觉质量下降。可植入性接触镜（ICL）植入术具有矫治范围大和矫治高度近视及超高度近视安全、有效、手术并发症少的优点，在视觉质量的评价方面也优于LASIK。进一步提出对高度近视患者于术方案的选择，旨在寻求最适合患者的手术方式，进而获得最佳的视觉质量。

Phakic intraocular lens implantation （PIOL） is one of the primary surgery fashions for correcting high myopia. The evaluation of visual quality following the surgery, including visual activity, contrast sensitivity, aberration and corneal Q value,is very important. Researches showed that the visual quality of patients after tradition laser in situ keratomileusis （LASIK） decreased because of the alteration of corneal asphericity by laser excision cornea;while compared with LASIK,implantation of implantable contact lenses （ICL） is popular due to its excellent safety,effectiveness,reversibility and fewer complication. The visual quality after ICL is also superior than that of I.ASIK. Therein,the surgical project will furthermore be recommend for the high myopia patients. The purpose is to find the optimal strategy for the high myopia patients to get the best visual quality.
