Clinical application of 8-0 polypropylene scleral-sutured fixed intraocular lens suspension implantation with the double knots technique in aphakic eyes

摘要:

目的：观察8-0聚丙烯缝线巩膜双联结缝合固定人工晶状体悬吊术在无晶状体眼中的临床效果。

方法：回顾性病例研究。收集2021-01/2022-11于我院行人工晶状体悬吊术的无晶状体患者30例31眼(其中男22例22眼)的临床资料，术中均采用8-0聚丙烯缝线巩膜双联结缝合法固定人工晶状体(AcrySof IQ或Tecnis ZCB00)，术后至少随访6 mo，观察所有患者视力、眼压、术后人工晶状体位置和术中术后并发症发生情况。

结果：术前术眼裸眼视力(UCVA，LogMAR)和最佳矫正视力(BCVA，LogMAR)分别为2.53±0.78和0.35±0.26，术后6 mo分别为0.58±0.26和0.36±0.27，手术前后UCVA比较有差异(t=15.408，P<0.01)，BCVA比较无差异(t=-1.677，P=0.104)。术中未出现并发症。术后所有人工晶状体位置均居中，出现人工晶状体倾斜3眼，术后发生高眼压2眼、角膜水肿5眼、缝线外露1眼。术后未出现前房积血、玻璃体积血、黄斑水肿、角膜内皮失代偿、低眼压、脉络膜脱离、视网膜脱离、爆发性脉络膜上腔出血、眼内炎等并发症。

结论：8-0聚丙烯缝线巩膜双联结缝合固定人工晶状体悬吊术早期可提高无晶状体患者的术后视力、并发症较少，可作为治疗无晶状体、晶状体脱位、悬韧带异常患者的一种手术方式选择。

Abstract:

AIM: To observe the clinical efficacy of 8-0 polypropylene scleral-sutured fixed intraocular lens(IOL)suspension implantation with the double knots technique in aphakic eyes.

METHODS: Retrospective case series study. The data of 30 aphakic cases(31 eyes, 22 males)that underwent IOL suspension in our hospital from January 2021 to November 2022 were collected. The suspension of IOL(AcrySof IQ or Tecnis ZCB00)was performed by 8-0 polypropylene scleral-sutured with the double knots technique. The visual acuity, intraocular pressure(IOP), IOL position and complications with at least 6 mo of follow-up were observed.

RESULTS: The mean preoperative uncorrected visual acuity(UCVA, LogMAR)and best-corrected visual acuity(BCVA, LogMAR)were 2.53±0.78 and 0.35±0.26, respectively, which were 0.58±0.26 and 0.36±0.27 at 6 mo postoperatively, respectively. And the differences in UCVA were statistically significant(t=15.408, P<0.01), whereas the difference in BCVA was not(t=-1.677, P=0.104). There were no intraoperative complications, with IOL position all centered, but 3 eyes had IOL tilt, 2 eyes had intraocular hypertension, 5 eyes had corneal edema, and 1 eye had suture exposure postoperatively. There were no complications such as hyphema, vitreous hemorrhage, macular edema, corneal endothelial decompensation, hypotony, choroidal detachment, retinal detachment, fulminant superior choroidal hemorrhage, endophthalmitis, or others.

CONCLUSION: The 8-0 polypropylene scleral-sutured fixed intraocular lens suspension implantation with the double knots technique can improve the postoperative visual acuity of aphakic patients, and fewer complications, which is an option for the treatment of aphakia, dislocation of the lens and ligament abnormalities.
