方法：回顾性分析2018-05/2020-12晶状体完全脱位于玻璃腔、核硬度3级及以上、并接受25G玻璃体切割、超声乳化术联合人工晶状体巩膜层间固定术的患者20例20眼。观察患者裸眼视力、最佳矫正视力、眼压、角膜内皮细胞计数、中央角膜厚度、并发症等。

结果：手术后裸眼视力、最佳矫正视力均较治疗前提高(P<0.05)。手术后角膜中央部位角膜内皮细胞计数较术前减少，但差异无统计学意义(P>0.05)。术后2wk中央角膜厚度与术前比较无差异(P>0.05)。患者中3眼出现低眼压，2眼出现眼压升高，但随访结束时均恢复正常。所有患者人工晶状体位置居中，未见明显偏心及倾斜。无玻璃体、视网膜并发症发生。

结论：25G玻璃体切割、超声乳化联合人工晶状体巩膜层间固定术治疗晶状体全脱位是一种快捷、安全、简便的手术方法。

METHODS: Totally 20 patients(20 eyes)with complete lens luxation and the hardness of lens nucleus was grade 3 or above who underwent 25G vitrectomy, phacoemulsification combined with intrascleral fixated IOL implantation between May 2018 and December 2020 were analyzed retrospectively. The uncorrected visual acuity, best corrected visual acuity, intraocular pressure, the count of corneal endothelium cell, central corneal thickness and complications were observed.

RESULTS: The uncorrected visual acuity and best corrected visual acuity after operation were improved than those before treatment(P<0.05). The number of corneal endothelial cells in the central part of cornea after operation was lower than that before operation(P >0.05). There was no significant difference in central corneal thickness 2wk after operation compared with that before operation(P >0.05). There were 3 cases of low intraocular pressure and 2 cases of high intraocular pressure, but they all returned to normal at the end of follow-up. The IOL were all centered and there were no obvious eccentricity and inclination. No other complications such as vitreous hemorrhage and retinal detachment occurred.

CONCLUSION: 25G vitrectomy, phacoemulsification combined with intrascleral fixated IOL implantation is a fast, safe and simple method for the treatment of complete lens luxation.
