Although the combined cataract and minimally invasive glaucoma surgeries (MIGS) were an appropriate surgical option, the presence of band keratopathy made it difficult to perform ab interno glaucoma surgery in her right eye (OD);therefore, the corneal opacity was removed using ethylenediaminetetraacetic acid (EDTA) chelation procedure. One month after chelation, microhook ab interno trabeculotomy and cataract surgery were performed successfully. Clear intraoperative visualization of the angle structures is critical for the success of these MIGS procedures. In glaucomatous eyes that require MIGS, EDTA chelation is a good neoadjuvant therapy for coexisting band keratopathy.展开更多
使用介质阻挡放电和脉冲电晕放电2种低温等离子体对电厂锅炉乙二胺四乙酸二钠(EDTA)清洗废水进行处理,采用COD降解率、色度去除率为评价指标,探寻放电功率、电介质间距(介质阻挡放电)/电极间距(脉冲电晕放电)、放电时间、处理量等因素对...使用介质阻挡放电和脉冲电晕放电2种低温等离子体对电厂锅炉乙二胺四乙酸二钠(EDTA)清洗废水进行处理,采用COD降解率、色度去除率为评价指标,探寻放电功率、电介质间距(介质阻挡放电)/电极间距(脉冲电晕放电)、放电时间、处理量等因素对COD降解率及色度去除率性能的影响。结果表明,当放电功率为15 k W,电介质间距/电极间距为5 mm时,2 h可使电厂锅炉EDTA清洗废水COD降解率70%以上、色度去除率90%以上。展开更多
