Results In 950 patients with successful cataractous operations,187 eyes(18.4%)had the vision of super-1.0,395 eyes(39.5%)had the Vision of 1.0-0.5,292 eyes(29.2%)had the vision of 0.5-0.3,106 eyes(10.4%)had the vision of 0.1-0.3,25 eyes(2.5)had the vislon of below-0.1.In 950 patients,242 eyes(24.2%)had diabetic retinopathy,15l eyes(15.1%)had aged-related macular degeneration,27 eyes(2.7%)had ischemic optic neuropathy,7 eyes(0.07%)had choroiditis,15 eyes(1.5%)had retinal vein occlusion,12 eyes(1.2%)had cystoid macular edema,5 eyes(0.2%)had traumatic retinopathy.

结果 950例患者的l 005只眼中，187只眼(18.4%)视力达1.0以上，395只眼(39.5%)视力在1.0-0.5，292只眼(29.2%)视力在0.5-0.3，106只眼(10.4%)视力在0.3-0.1，25只眼(2.5%)视力低于0.1.950例患者的1005只眼中，242只眼(24.2%)息有糖尿病视网膜病变，151只眼(15.1%)息有老年性黄班变性，27只眼(2.7%)息有缺血性视神经病变，7只眼(0.07%)息有陈旧性脉络膜炎，15只眼(1.5%)患有视网膜静脉闭塞，12只眼患有黄斑囊样水肿(1.2%)，5只眼(0.05%)患有外伤性视网膜病变。

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。

An individual with 20/40 vision can read letters on an eye chart from 20 feet away, while a person with normal 20/20 vision can read the chart from 40 feet away; 20/40 vision is good enough to get a driver's license in most states.

20/40的视力是可以站在20英尺外看清楚视力表上的字母，而一个视力为20/20的人则可以站在40英尺外看清楚实力标上的字母，20/40的视力是可以在美国很多州申请到驾照）。

RESULTS: In the 1105 girl students examined, the average interpupillary distance was 59.27mm in the normal eyesight group and 59.35mm in the myopia group, without significant difference by statistical treatment.

结果：1105名受检青年女性中，视力正常组与近视眼组的瞳距均值分别为59.27，59.35mm，两组瞳距比较经统计学处理无差异性存在；眼球突出度均值视力正常组为15.49mm，近视眼组为15.76mm；视力正常眼，轻度、中度、高度近视眼各组人群测定眼球突出度经方差分析比较有显著性差异（F=6.108，P.01），4组人群眼球突出度经LSD处理后两两比较：视力正常眼与中、高度近视眼，高度近视眼与轻、中度近视眼等4组之间均有显著性差异（P.05）；各组眼球突出度左、右眼间比较，差异均无显著性。

Twenty-twenty 视力正常的 I am a twenty-twenty student but many of classmates are near-sighted.

我班的许多同学都得了近视，可我的视力却很正常。

One of the most serious injury was the weeder is sprayed from a small stone hit the case, as a result of the breakdown of the eye, despite surgical suture, but almost blind; all of the cases, about 53% of vision can be restored to more than 0.5 good Degree of visual medium, about 0.2 to 0.4 between 10% and 0.1 vision in more than 23%, while other recovery is unknown, about 40 visually impaired.

其中伤势最严重的是被除草机喷起的小石头击中的病例，因眼球破裂，虽经手术缝合、但仍几乎全盲；全部的个案中，约有53%视力能恢复到0.5以上的良好程度，视力中等约0.2到0.4之间占10%，视力在0.1以上的则有23%，其他则恢复情况不明，视力受损约有四成。

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。

Result: Following up 3～12 months (average 6 months), the corrected vision was from 0.1 to 1.0 and 28 eyes corrected visual acuity were more than 0.3 (82.4%). Poor vision was because of the fundal diseases. 3 eyes intraocular pressure increased postoperation,then decreased to the normal range with medicine. All eyes had no complication.

结果：随访3—12月，平均随访半年，复查时矫正视力最佳1.0，最低0.1，视力≥0.3者28眼（占82.4%），视力≥0.6者20眼（占58.8%），视力偏低多为眼底病变所致。34眼中，术后早期眼压增高者3眼（占8.8%），经用降眼压药后均降至正常范围。34眼中术后均无明显并发症。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
