准分子激光手术术后视觉质量评价

Visual quality in myopia patient after excimer laser operation

准分子激光手术不仅要改善屈光不正患者术后的裸眼视力及最佳矫正视力,同时也要保证患者术后的视觉质量。视觉质量主要是通过近视患者手术后的客观视力、像差、对比敏感度与眩光敏感度、非球面参数(Q值)、主观视觉生活质量、优势眼改变以及双眼视功能等方面来评价,本文就此几个方面进行综述。

Excimer laser not only should improve refractive error patients, uncorrected visual acuity and best corrected visual acuity, but also preserve the visual quality. Visual quality is evaluate by objective vision,aberration,contrast sensitivity, glare sensitivity, asphericities （ Q-values ）, subjective visual acuity, alternative of dominant eye, visual performante of both eyes. Now the article summarize from around these parts.
