高度近视眼白内障手术中的后囊处理

目的：探讨高度近视眼白内障手术中后囊的处理。方法：高度近视眼白内障患者22例30只眼，平均眼轴长度31.62mm，行3.0mm常规白内障超声乳化，术中行后囊连续环形撕囊术12只眼，行后囊切开联合前部玻璃体切割术18只眼，未植入人工晶体。结果：所有病例在术后裸眼视力提高，后囊连续环形撕囊组视力≥0．1者100％，其中视力≥0．3者占58．3％；后囊切开联合前部玻璃体切割组视力≥0．1者为88．9％，其中视力≥0．3者占50％。术中及术后并发症；后囊连续环形撕囊组中未出现并发症；后囊切开联合前部玻璃体切割组一例出现脉络膜脱离，二例3只眼发现视网膜破孔。结论：后囊连续环形撕囊术是减少高度近视患者白内障术后并发症的安全，经济，有效的方法，在未植入人工晶体眼也适用。

The Management of Posterior Capsular in Cataract Operations of High Myopia

OBJECTIVE: To study the management of posterior capsular in cataract operation of high myopia in order to avoid posterior capsular opacity(PCO). METHODS: Twenty-two cases(30 eyes) of high myopia with an average axial length of 31.62 mm were analyzed. Cataract phacoemulsification were performed in all cases, among which 12 eyes were operated with continuous curvilinear capsulorhexis (group I) of posteror capsular and 18 eyes were operated with capsulorectomy combined with anterior segment vitrectomy (group II). No artificial lenses were implanted in all cases. RESULTS: The post-operative naked vision were improved in both groups. Group I: The VA > or = 0.1 in all 12 eyes(100%), > or = 0.3 in seven eyes (58.3%) and no complication happened. Group II: The VA > or = 0.1 in 16 eyes(88.9%), > or = 0.3 in nine eyes (50%), and one eye with hemmorhage choroid detachment in the operation and three eyes with retina tear after the operation. CONCLUSION: Continuous curvilinear capsulorhexis of posteror capsular in treating PCO of high myopia with cataract is a safe effective and economic way compared with capsulorectomy combined with anterior segment vitrectomy.
