The best corrected visual acuity ( BCVA) and macular structural changes were observed before the surgery, and at1,2,3,4,8 months after the surgery.

手术后1、2、3、4、8个月复查，对比观察手术前后最佳矫正中心视力和黄斑部的结构变化。

The Best Correct Visual Acuity ( BCVA) was 1 02 ± 0 16 in group one, and 0 96 ± 0 17 in group two.

第一组最佳矫正视力为1.02±0.16，第二组为0.96±0.17。

Pre-and postoperative refraction and best corrected visual acuity ( BCVA) were registered.

记录术前、术后的屈光度和最佳矫正视力（BCVA）。

Blind: The best corrected visual acuity ( BCVA) of good eye was less than 0.05;

视障情况：全盲为好眼的最佳矫正视力低于0.05；低视力指好眼的最佳矫正视力低于0.3。

Results Preoperative BCVA was finger counting to 0.05 in all 15 eyes.

结果术前15眼视力均≤0·05。

There was also no difference in the BCVA between the two groups.

并且两组的最佳视觉敏感度没有差异。

At 24 months, there were 3 eyes ( 3.8%) had lost 2 or more lines of BCVA because of secondary keratoconus.

再次术后24月最佳矫正视力与再次术前相比下降2行以上的3眼占3.8%。

Methods The condensation of 2-bromo-5,6-dimethoxy-indan-1-one with various aminoalkyl phenols in the presence of ( K_ ( 2) CO_ ( 3)) and acetonitrile gave the corresponding title compounds, and the in vitro AchE and BchE inhibitory activities were evaluated by the modified Ellman method.

方法在K2CO3和乙腈存在下，将2-溴-5,6-二甲氧基-1-茚酮与多种胺烷基苯酚缩合得到一系列苯氧茚酮类衍生物，并采用改进的Ellman方法研究它们的体外AchE和BchE抑制活性。

The BChE was purified to electrophoretic homogeneity by salting out, ion-exchange chromatography on DEAE-cellulose and gel filtration on Sephadex G-200. Finally the enzyme was purified 278. 5 folds and the enzyme activity recovery ratio was 17.8%.

该酶经过两次硫酸铵盐析、DEAE-52离子交换层析和Sephadex G-200凝胶过滤层析后，其比活力由21.5U/mg提高到5944.1U/mg，纯化278.5倍，回收率为17.8%，达到电泳纯。
