目的 分析Ozil横向扭动模式的超声能量场分布特征,对Ozil轴向控制的必要性及其对眼内非靶组织的影响进行评估.方法 对2011年7月至2012年6月在无锡市第二人民医院眼科选择老年白内障手术病例126例(126只眼),年龄65～80岁,平均68.4岁;男54例(54只眼),女72例(72只眼).分组:Ozil轴向控制组:60例(Ⅱ级14只眼,Ⅲ级20只眼,Ⅳ级26只眼);非轴向控制组:未进行轴向控制的回顾性病例,66例(Ⅱ级14只眼,Ⅲ级22只眼,Ⅳ级30只眼).两组病例同等硬度核术中使用的超声模式相同,就两组病例术后累积能量复合参数、术后8～10 h眼压、术后24 h角膜水肿平均度进行对照.结果 使用相同乳化模式下,Ozil轴向控制组病例术后24 h角膜组织水肿平均度明显低于非轴向控制组病例(x2=5.41,P＜0.05);术后8～10 h眼压升高幅度亦低于非控制组病例(t =2.069,P＜0.05);两组病例的累积能量复合参数差异无统计学意义.结论 Ozil横向扭动超声具有不同于传统超声能量场的分布特征,横向扭动在手术空间内产生的终端能量场具有轴向特征;轴向控制可以使横向扭动的超声能量获得精确控制,提升其效率与安全性.
目的 分析Ozil橫嚮扭動模式的超聲能量場分佈特徵,對Ozil軸嚮控製的必要性及其對眼內非靶組織的影響進行評估.方法 對2011年7月至2012年6月在無錫市第二人民醫院眼科選擇老年白內障手術病例126例(126隻眼),年齡65～80歲,平均68.4歲;男54例(54隻眼),女72例(72隻眼).分組:Ozil軸嚮控製組:60例(Ⅱ級14隻眼,Ⅲ級20隻眼,Ⅳ級26隻眼);非軸嚮控製組:未進行軸嚮控製的迴顧性病例,66例(Ⅱ級14隻眼,Ⅲ級22隻眼,Ⅳ級30隻眼).兩組病例同等硬度覈術中使用的超聲模式相同,就兩組病例術後纍積能量複閤參數、術後8～10 h眼壓、術後24 h角膜水腫平均度進行對照.結果 使用相同乳化模式下,Ozil軸嚮控製組病例術後24 h角膜組織水腫平均度明顯低于非軸嚮控製組病例(x2=5.41,P＜0.05);術後8～10 h眼壓升高幅度亦低于非控製組病例(t =2.069,P＜0.05);兩組病例的纍積能量複閤參數差異無統計學意義.結論 Ozil橫嚮扭動超聲具有不同于傳統超聲能量場的分佈特徵,橫嚮扭動在手術空間內產生的終耑能量場具有軸嚮特徵;軸嚮控製可以使橫嚮扭動的超聲能量穫得精確控製,提升其效率與安全性.

Objective To analyze the actual terminal phacoemulsification energy effect in intraocular space,axis motion control model of Ozil torsional handpiece and to evaluate the necessity and the impact of the non-target tissues within the eye.Methods Induced by high aspiration pressure (300～350mmHg),hard nucleus (Grade:Ⅲ～Ⅳ) of senile cataract was chopped before phacoemulsification in 126 patients (126 eyes).Sixty patients (60 eyes) accepted ultimate energy control on the base of Ozil torsional handpiece axis control model; Another 66 patients (66 eyes) were compared as the Ozil torsional handpiece non-axis control group.The differences of accumulated energy complex and 8～10 hr postoperation intraocular pressures (IOP) and 24hr postoperation comeal edema rate were compared between two groups.Results The difference of accumulated energy complex was compared between two groups.(t =2.263,P ＜0.05).Difference of 8～10hr postoperation IOP existed between two groups.(t =2.069,P ＜0.05).The rates of 24hr postoperation corneal edema was lower in energy dissipation control group than that in the reviewed group (x2=5.41,P ＜0.02).Ozil torsional handpiece axis control could focus phaco energy terminal effects more precisely and protect non-target tissues injuries from energy dissipation.Conclusions Ozil torsional handpiece axis control can minimize the level of dissipated energy and improve the accuracy and safety of Ozil phaco mode.
