查询词典 visual acuity

The main outcome measures were uncorrected distant visual acuity , best corrected distant visual acuity , uncorrected near visual acuity , distant-corrected near visual acuity , the best corrected near visual acuity , defocus curves and depth of focus, the rate of posterior capsule opacification of the study group, IOL decentration distance of the study group. A questionnaire was applied to evaluate the visual function and rate of spectacles usage.

术后检查内容包括：术后裸眼远视力、最佳矫正远视力、裸眼近视力、矫正远视力时的近视力、最佳矫正近视力；在两组患眼中选择最佳矫正远视力≥0.9的患眼进行焦点深度及离焦曲线测量；观察实验组后囊膜混浊情况；选取实验组的部分病例进行散瞳裂隙灯照相测量人工晶状体偏中心的距离。

The visual acuity, dioptometry and corneal topography were investigated in a 12-month follow-up study.results the postoperative visual acuity of the 56 eyes(84.8%)was equal to or above the best corrected visual acuity before lasik.conclusion lasik for ametropia after cataract extraction and intraocular lens implantation is an effective and safe surgery.but the indication must be selected appropriately.

观察视力、屈光状态、角膜地形图情况。结果 56眼（84.8%）lasik术后视力均达到或超过术前的最佳矫正视力，10眼（15.2%）lasik术后最佳矫正视力下降1～2行。结论 lasik是矫治白内障摘除人工晶体植入术后屈光不正的安全、有效的方法。

In older age group, the visual acuty of Comprehensive refractometer is higher than Visual projector and Visual box. The difference of the visual acuity may be caused by the different contrast in different background luminance and visual box luminance.

在老年组的裸眼视力测量结果中，综合验光仪好于视力表投影仪和视力表箱，这种视力测量的差异可能是由于不同背景亮度及视标照度下视标的对比度不同所引起。

This investigation shows that exotropia was found more frequently in distance lateral phoria in myopes. Stereopsis acuity negatively correlated with the degree of my-opia and subjects with a lower stereopsis acuity had a higher degree of myopia. There was no significant correlation between distance lateral phoria and stereopsis acuity.

本组近视眼视远时水平隐斜视中，外斜偏多；立体视锐度与近视屈光度呈正相关，立体视锐度较差者多分布于近视眼度数较大患者中；近视眼人群中视远时水平隐斜视和立体视锐度无显著相关。

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。

Objective Through visual acuity research after modern extracapsular cataract extirpation and intraocular lens implantationoperation, we will improve the technology and method to make patients obtain good visual acuity.

目的 通过对297例（315眼）现代白内障囊外摘除人工晶体植入术后视力研究，进而改进技术和方法，使患者获得良好视力。

With the amount of anisometropia increased,the stereo-visual acuity decreased(t test P＜0.05) and the stereopsis visual acuity of "simple" hypermetropia decreased more significantly than that of "simple" myopia of the same amount.

立体视敏度随着屈光参差度数的增加而下降(t检验，P＜0.05)，相同程度的单纯远视性屈光参差比单纯近视性屈光参差立体视敏度下降更明显(t检验，P＜0.05)。

Methods For the cosmetic purpose of 26 cases of full-cornea leucoma without visual acuity and of the leucoma deviated from pupil with better visual acuity, the lamellar keratoplasty plus interlamellar dyeing with tattoo-eyebrow liquid was adopted. The postoperative follow-up ranged from 1 year to 4 years (2.5 years on the average).

对26例丧失视力的全角膜白斑和白斑偏离瞳孔且视力尚可的患者，为达到美容目的，采取板层角膜移植加层间染色术，用文眉液做染色剂。

METHODS:We examined the visual acuity of preschoolers aged 4-6 years after precluding the organic disease in the six public kindergartens in Daxing district.Children with visual acuity ≤0.8 and strabismus underwent skiascopy.

对我区6所公立园所4～6岁学龄前儿童给予系统检查，排除器质性病变后进行视力检查，对视力低常和斜视者(≤0.8)进行验光检测。

Mean spherical equivalent, uncorrected visual acuity, best spectacle-corrected visual acuity, and higher wavefront analyses were determined.

低劣的球同等物，不改正视觉的锐敏，最好值得看的东西改正的视觉锐敏和较高的波前分析被决定。
