  • 简介:AIMTo评估关于光质量的培植根据包括的decentering.METHODSThis的不同的度估计了的V4c可植入的collamer透镜(洞ICL)的临床的结果收到了常规ICL的49只眼睛和收到了洞ICL的94只眼睛。收到了洞ICL的眼睛根据decentering的度被划分成三个组:组织1,在从学生中心的1条洞直径(HD)以内的中央洞;组织2,在到2HD的1HD以内的中央洞;并且组织3,在到3HD的2HD以内的中央洞。视觉尖酸(VA),intraocular压力(IOP),和球形的等价物(SE)价值在1wk被估计,1并且在外科以后的3mo。在surgery.RESULTSThere不是在VA,IOP,和SE的重要差别在之中以后,眼睛的调整转移功能,Strehl比率,客观散布索引,和更高的顺序错误(HOA)在3mo为4公里学生被测量常规并且洞ICL组。关于HOA,为昏迷和球形的错误的价值没显示出差别。全部的HOA和翘摇价值在比在组1的组2是显著地更高的(P=0.02,0.03,分别地)。在surgery.CONCLUSIONOur结果建议洞ICL培植提供等价于由常规ICL提供了那的令人满意的视觉质量以后,在关于在3mo的另外的光优秀参数的组之中没有重要差别,不管decentering的中央洞和度的存在。

  • 简介:我们的学习回顾地考察了外科的结果直到经历了trabeculectomy(n=18)或phacotrabeculectomy(n=20)的38个连续中国绿内障病人的3mo。基线年龄,视觉尖酸,和intraocular压力是可比较的。到3mo的从手术后的1d的Intraocular压力在2个组之间是类似的。完全的成功被获得在65%phacotrabeculectomy,和66.7%trabeculectomy盒子;当失败发生了在时16.7%phacotrabeculectomy,和在3mo的10%trabeculectomy盒子。Phacotrabeculectomy组一致地在视觉尖酸显示出更好的改进。弥漫的水泡发生在65%phacotrabeculectomy和83%trabeculectomy眼睛;并且在trabeculectomy以后的在35%phacotrabeculectomy的扁平的水泡,而是没有。在phacotrabeculectomy以后有更多的hypotony(5%对0)。得出结论,phacotrabeculectomy和trabeculectomypost-operatively表明了可比较的intraocular压力控制直到3mo。然而,phacotrabeculectomy病人最好视觉尖酸改进。尽管如此,更弥漫的水泡和更少hypotony是在场的跟随trabeculectomy。

  • 简介:这篇文章在优秀通货膨胀的存在下面与消费者参考质量效果学习联合定价和动态产品质量投资的一个问题。最佳的控制模型被构造与一个有限优秀投资能力最大化全部的利润,在需求对历史的产品质量水平敏感的地方。为有限、无限的计划地平线的最佳的优秀投资策略被根据Pontryagins最大的原则解决这些最佳的控制模型分别地给,它随着时间的过去与引用质量效果使最佳的优秀投资的准确轨道能被描绘。另外,一个有效算法被设计为系统产生最佳的联合定价和动态优秀投资政策。有限计划地平线和无限的计划地平线的策略之间的主要差别是后者是一个常数。我们的学习显示公司在整个计划地平线一路上增加优秀投资从来不是最佳的。当考虑参考质量的影响时,优秀投资的水平更高。而且,数字例子被给说明理论结果的正当。另外,敏感分析被执行显示出系统参数怎么影响最佳的政策,并且一些经理的建议被介绍。
