目的：观察改良四点固定人工晶状体悬吊植入术在无晶状体眼中的有效性及安全性。

方法：前瞻性研究。选2020-10/2021-05于我院行改良四点固定人工晶状体悬吊植入术的无晶状体眼患者32例32眼，平均年龄44.56±8.48岁。观察手术前后裸眼视力(UCVA)、最佳矫正视力(BCVA)、角膜散光、术中及术后并发症。

结果：所有患者平均随访4.84±0.64mo，术前UCVA、(LogMAR)为1.25±0.42，末次随访时为0.5±0.25(P<0.001)； 术前BCVA(LogMAR)为0.41±0.19，末次随访时为0.42±0.19(P>0.05)； 术前角膜散光为1.17±0.64D，末次随访时为1.20±0.59D(P>0.05)。术中无并发症发生，术后发生低眼压2眼、高眼压1眼、角膜水肿2眼，无前房积血、玻璃体积血、黄斑囊样水肿、角膜内皮失代偿、人工晶状体倾斜或偏心、缝线外露等并发症。

结论：改良四点固定人工晶状体悬吊植入术可显著提高无晶状体眼患者术后视力、未增加额外角膜散光、并发症少。

METHODS:A prospective study. A total of 32 aphakic patients(32 eyes)with an average age of(44.56±8.48)years who underwent modified four-point fixed intraocular lens suspension implantation in our hospital from October 2020 to May 2021 were selected. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), corneal astigmatism, intraoperative and postoperative complications were observed before and after operation.

RESULTS:The mean follow-up of all patients was(4.84±0.64)mo. The preoperative UCVA(LogMAR)was 1.25±0.42 and the last follow-up was 0.5±0.25(P<0.001). The preoperative BCVA(LogMAR)was 0.41±0.19 and the last follow-up was 0.42±0.19,(P >0.05). The preoperative corneal astigmatism was(1.17±0.64)D and the last follow-up was(1.20±0.59)D(P>0.05). There were no intraoperative complications, but 2 eyes had low intraocular pressure, 1 eye had high intraocular pressure and 2 eyes had corneal edema occurred after operation. There were no complications of hyphema, vitreous hemorrhage, macular cystoid edema, corneal endothelial decompensation, inclination or eccentricity of intraocular lens and exposure of suture.

CONCLUSION:The modified four-point fixed intraocular lens suspension implantation can significantly improve the postoperative visual acuity of aphakic patients without additional corneal astigmatism,and with fewer complications.
