放射

Purpose: To evaluate the efficacy and safety of Mitomycin-C use in inhibiting haze formation of photorefractive keratectomy eyes following undercorrected radial keratotomy.

目的：以雷射屈光角膜切除术并用Mitomycin-C治疗屈光欠矫之放射状角膜切开术病例，评估其安全性及抑制术后角膜雾浊的效果。

Until the 1990s, surgical treatment involved a procedure called radial keratotomy, which entailed making radial cuts in the corneal surface to flatten the curvature to correct myopia.

直到20世纪90年代，外科治疗所涉及的一个程序，所谓的放射状角膜切开术，其中涉及决策径向削减在角膜表面平坦的曲率，以纠正近视。

Methods One stage radial keratotomy and second stage DLKP were performed, the uncorrected and corrected visual acuity, refractive status and results of slit-lamp microscopic examination were followed up for 4 years.

对1例急性圆锥角膜水肿患者，采用I期放射状角膜切开术、Ⅱ期DLKP术的方法治疗，对患眼裸眼及娇正视力、屈光状态、裂隙灯检查结果进行观察，随访期4年。

Eyeglasses, vision exams, contact lenses, hearing tests, hearing aids, hearing implants, eye refraction, visual therapy, orthoptics or visual eye training or eye surgery (including cataract surgery and radial keratotomy) or for any examination or fitting related to these devices or procedures.

眼镜，视力考试，隐形眼镜，听力测验，助听器，听力植入，视力矫正，视觉疗法，视觉矫正视力或眼睛培训或眼科手术（包括白内障手术和放射状角膜切开术），或作任何考试或装修相关的这些设备或程序。

Results First stage radial keratotomy could effectively promote healing after corneal hydrops in the acute stage in this patient. The Descemet's membrane could be completely exposed during second stage DLKP, and the operation was successfully done without mircro-puncture during the whole procedure.

结果 该患者在急性圆锥角膜水肿阶段，采用放射状角膜切开术能有效控制急性期的各种症状，Ⅱ期DLKP术中能够完整的暴露角膜后弹力层，术中无后弹力层微穿孔发生。

In addition, there is a "pseudo-myopia", which due to excessive use of regulatory role For example, in children, adolescents reading, the reading with the eye too close a distance, it is bound to increase the regulatory role of the eye, causing ciliary muscle function to enhance or spasm, this occurrence of myopia in school, and family to learn some of the irrational factors , for example, a natural classroom lighting, lighting, lighting, seating, seated, excessive use eyes, pay attention to eye health, eye fatigue is closely related to myopia is divided into mild myopia (-3D below); moderate myopia (-- 3D - 6D),-6D or more as high myopia, myopia authenticity required to wear appropriate glasses, children and adolescents need to be fully dilated in the absence of regulating state optometry, refraction measured by the eye itself, after the age of 18 , in the myopia progression-free circumstances, do radial keratotomy to correct myopia.

此外尚有一种"假性近视"，其因过度运用调节作用，例如在儿童、青少年读书时，读物与眼球的距离过于接近，势必增加眼球的调节作用，引起睫状肌功能增强或痉挛，这种近视的发生与在学校以及家庭学习的一些不合理因素有关，例如教室的自然采光，灯光照明，坐位、坐姿，过度用眼，不注意用眼卫生、眼疲劳有密切关系，近视眼又分为轻度近视（－3D以下）；中度近视（－3D—－6D），－6D以上者为高度近视，真性近视需配戴合适的眼镜，儿童和青少年均需充分散瞳，在无调节状态下验光，测出眼球本身的屈光度，18岁以后，在近视无进展的情况下，可做放射状角膜切开术，以矫正近视。
