视力

Tests of preliminary models show this conversion can be done to better than 3 cm, and that random error in GPS height is of greater concern.

试验表明该模型的初步，可转换视力测定比3厘米，随机误差在全球定位系统的高度是更大的关注。

The induced changes in log mesopic contrast sensitivity showed significant negative correlation with the changes in third-order (r =-0.490, P =.0013 without glare; r =-0.362, P =.0177 with glare; Spearman rank correlation coefficient) and fourth-order root mean square (r =-0.586, P =.0001 and r =-0.306, P =.0450, respectively).

中间视力对比敏感度log值的变化与三阶像差(r =-0.490， P =。0013 无眩光； r =-0.362， P =。0177 ，有眩光； Spearman 等级相关系数)和四阶像差(r =-0.586， P =。0001无眩光；； r =-0.306， P =。0450有眩光，)的均方根呈显著负相关。

Results All cases had got retinal reattachment, and their postoperative vision improved in different level.

结果 全组32眼术后视网膜脱离均成功的复位，术后视力有不同程度的提高。

The visual acuity of 25 cases was increased and 11 eyes (91.7%) retina reattachment after follow-up period for 3 to 10 months.

术后随访观察3~10个月，31只眼中25只眼视力不同程度提高，11(91.7%)眼视网膜复位。

Glare and refection off the monitor can cause eye problems leading to blurred vision.

眩光及茶点序幕监测可造成眼部问题导致视力模糊。

Main outcome measures were done on final visual acuity, early complications and refractional deviation.

主要记录患者最佳矫正视力，早期并发症及屈光偏差。

The refractional condition,ocular position and their relationship in six hundred and fifty eyes of 325 healthy youths 16-18 yr.

调查16～18岁视力正常男性325人650眼的屈光状态、眼位以及它们之间的关系。

AIM: To analyze the postoperative visual outcome, early complications and refractional deviation of secondary intraocular lens implantation for traumatic cataract caused by open-globe injury.

目的：分析开放性眼外伤二期人工晶状体（intraocular lens， IOL）植入术后的视力、早期并发症及屈光偏差。

The goal of refractive surgery is to improve a patient's vision.

的目标，屈光手术是改善患者的视力。

RESULTS:There was obvious difference between the observation group and the control group on solving visual regression and establishing triple visual function.

结果：观察组与对照组在解决儿童视力回退及建立三级视功能的问题上，有显著差异。
