免水分离超声乳化白内障摘除术临床观察

The clinical observation of phacoemulsification with intraocular lens implantation without hydrodissection

目的 :探讨免水分离术在超声乳化白内障摘除术中临床应用的有效性。方法 :随机选择白内障患者 2 0 0只眼 ,分两组。一组 (对照组 ) 95例 10 0只眼进行常规水分离术 ,二组 (观察组 ) 94例 10 0只眼 ,行免水分离术 ,所有患者均由同一医师进行超声乳化白内障摘除术联合人工晶体植入。临床观察超声乳化能量和时间 ,术后第一天、第三天、一周时视力 ,术中、术后并发症。结果 :( 1)平均超声能量Ⅰ、Ⅱ、Ⅲ、Ⅳ级核 ,一组分别是 :( 10 5 6± 4 16) %、 ( 17 88± 2 2 6) %、 ( 2 9 2 2± 3 5 4) %、 ( 3 7 88± 2 67) % ;二组分别是 ( 11 3 0± 1 89) %、 ( 18 76± 1 61) %、 ( 2 7 99± 3 5 8) %、 ( 3 9 2 2± 3 3 3 ) % ;两组平均超声能量差异无显著意义 (t =-0 5 12、 -1 496、 1 70 6、 -1 3 60 ,P =0 615、 0 14 2、 0 0 91、 0 182 ) ;平均超声时间一组分别为 ( 7 5 6±3 2 1)s、 ( 2 6 68± 5 15 )s、 ( 71 72± 17 2 2 )s、 ( 13 7 71± 3 8 60 )s ,二组分别为 ( 9 10± 1 2 0 )s、 ( 2 4 71± 4 0 9)s、 ( 76 17± 18 74)s、 ( 12 2 0 9± 3 5 14 )s ,两组平均超声时间差异无显著意义 (t =-1 42、 -1 415、 -1 3 69、 1 3 3 3 ,P =0 173、0 164、 0 174、 0 190 )。 ( 2 )

Objective:to investigate the clinical effect of phacoemulsification with intraocular lens implantation without hydrodissection. Methods:200 eyes of cataract patients with nucleus of the lens in Grade Ⅰ?Ⅱ?Ⅲ?Ⅳ were divided into 2 groups,the first group(95 cases,100 eyes) accepting regular hydrodissection,and the second group (94 cases,100 eyes) without the hydrodissection procedure.The energy and time of phacoemulsification,the vision in 1 st ,3 rd & 7 th day after operation,and the subsequent diseases perioperation were analyzed. Results:The average energies and times of phaco between 2 groups were no difference (P>0 05).The vision after operation and the subsequent diseases between 2 groups were also no difference (P>0 05). Conclusions:Phacoemulsification with intraocular lens implantation without hydrodissection can obtain the same clinical result with regular mode if the technique of phacoemulsification mastered.
