超声乳化白内障摘除术中后囊破裂的Ⅰ期后房型人工晶体植入术

目的评价超声乳化白内障摘除术中后囊破裂的Ⅰ期后房型人工晶体植入术的疗效。方法对１８４例（２００只眼）施行超声乳化白内障摘除术中后囊破裂者２９例（２９只眼）行Ⅰ期后房型人工晶体植入术。结果１０例囊袋内植入,１９例睫状沟植入。术后３个月随访,裸眼视力１．０以上者１７例（５８．６２％）,０．５～０．９者１０例（３４．４８％）;矫正视力１．０以上者２２例（７５．８６％）,０．５～０．９者５例（１７．２４％）。本组并发症主要为角膜水肿,瞳孔缘虹膜咬伤,前段玻璃体炎症等。结论对于后囊破裂及玻璃体脱出的患者,适当利用残留的前、后囊作为支撑,清除前段玻璃体,仍可植入后房型人工晶体。

Primary posterior chamber intraocular lens implantation of posterior capsular ruptur with cataract extracted by phacoemulsification

OBJECTIVE: To evaluate the effect of primary posterior chamber intraocular lens (IOL) implantation of posterior capsular rupture (PCR) with cataract extracted by phacoemulsification. METHOD: Primary posterior chamber IOL implantation was performed on 29 cases (29 eyes) with PCR occurring in 184 cases (200 eyes) during cataract extraction by phacoemulsification. RESULTS: In-the-bag implantation was performed on 10 cases, and sulcus-fixed lens implantation on 19 cases. The post-operative uncorrected visual acuities in 17 cases (58.62%) were 1.0 or better and 0.5 - 0.9 in 10 cases (34.48%). The corrected visual acuities in 22 cases (75.86%) were 1.0 or better and 0.5 - 0.9 in 5 cases (17.24%) after 3 months of operation. The complications included corneal edema and damage of pupillary margin in the operation, and anterior vitreous inflammatory reaction after the operation. CONCLUSION: The posterior chamber IOL can be primarily implanted in cases with PCR and functional anterior or posterior capsular support after the anterior segment vitreous was cleaned.
