Results In the 121 patients, 47 patients(39%) were accommodative failure, 66 patients(55%) were lag of accommodation checking with FCC, 53 patients (43.8%) were uncorrected presbyopia, 65 patients (53.7%) were break up time of tear film＜10s, 87 patients (71.8%) couldn't been corrected the refraction errors or the correction of refractive errors was unsatisfied, 24 patients(19.8%) were esophoria, 17 patients (14%) were exophoria, 8 patients (7%) were anisometropia.

结果 121例患者中，调节灵活性明显降低者47例，占39%；FCC检查调节滞后者66例，占55%；未矫正老视者53例，占43.8%；泪膜破裂时间＜10s者65例，占53.7%；屈光矫正不足或未予矫正者87例，占71.8%；内隐斜者24例，占19.8%；外隐斜者17例，占14%；屈光参差者8例，占7%。

In such a medium, the direction of the Poynting vector monochromatic plane wave is antiparallel to that of its phase velocity. Because of that, DNG displays some unusual electromagnetic properties such as backward-wave effect, negative refractive effect, perfect lens and a limit situation, zero index of refraction materials.

在这种材料中，单色均匀平面波的相速方向和坡印亭矢量方向是相反的，因此使双负材料表现出一系列反常的电磁特性如：回波效应、负折射效应、完美透镜效应和一种极限情况即零折射率材料等。

The soft contact lens is acceptable for aphakia children under the monitor of their parents.It improves the visual acuity,binocular fusion and stereo visual acuity.It can be used as early as possible for monocular aphakia children to prevent the amblyopia and refractive strabismus.

婴幼儿在其监护人的帮助下，配戴接触镜是安全的，视力较矫正前明显提高，斜视的避免关键在于坚持规范配戴和积极的弱视治疗，戴镜后屈光参差减少，双眼融合功能和立体视得到改善，从而提高了视觉质量。
