方法：对晶状体脱位(Ⅱa型及Ⅱb型)患者23例23眼行囊袋内超声乳化手术，术中行Ⅰ期人工晶状体植入，对术中及术后并发症、术后视力、眼压、角膜内皮细胞、人工晶状体位置等情况进行观察。

结果：所有患者均按照预定手术方案顺利完成手术； 术中未发生晶状体核或其碎块坠入玻璃体腔； 术后1d角膜水肿20例，眼压升高17例，未出现人工晶状体偏位或移位及视网膜脱离等严重并发症； 术后1wk平均眼压为(15.81±2.10)mmHg，与术前比较差异有统计学意义(P<0.01)，术后1wk所有病例视力均有不同程度提高，与术前比较差异有统计学意义(P<0.01)，术后1wk角膜内皮细胞密度及六角形细胞百分比下降，变异系数增大，但与术前比较差异无统计学意义(P>0.05)。

结论：囊袋内超声乳化联合Ⅰ期人工晶状体植入术治疗晶状体全脱位(Ⅱa型及Ⅱb型)能够有效恢复患者视功能并控制眼压，减少对角膜内皮细胞的损伤，是治疗是外伤性晶状体脱位的有效方法。

METHODS: A total of 23 cases(23 eyes)of lens dislocation(IIa and IIb)were underwent innercapsular phacoemulsification combined with primary IOL implantation. IOL implantation were underwent during operation, the complications of intraoperative and postoperative, postoperative vision, intraocular pressure(IOP), corneal endothelial cell, IOL location were analyzed.

RESULTS: The operations were successfully completed for all patients in accordance with the pre-surgery program; lens nucleus or its fragments did not crash into the vitreous cavity; 20 cases of corneal edema and 17 cases of IOP presented at the first day after surgery, the deviation or displacement of IOL and serious complications such as retinal detachment were not appeared. At the first week postoperation, the average IOP was 15.81±2.10mmHg, with statistically significant differences when compared with the preoperative(P<0.01), the visual acuity in all eases increased, with statistically significant differences when compared with the preoperative(P<0.01). Corneal endothelial cell density and percentage of hexagonal cells decreased, the variation coefficient increased in first week of postoperative, with no statistically significant differences when compared with the preoperative(P>0.05)

CONCLUSION: Innercapsular phacoemulsification combined with primary IOL implantation in the treatment of the whole lens dislocation(Ⅱa and Ⅱb)can restore function in patients with diplopia and control IOP effectively, reduce corneal endothelial cell damage, which is an effective method to treat the whole traumatic lens dislocation.
