To report a new technique for sutureless intrascleral fixation of three-piece foldable intraocular lenses (IOLs) using 25-gauge trocars.
We performed this technique on patients with insufficient posterior capsule support. Seventeen eyes from 15 patients with aphakia, dislocated IOL, or subluxated crystalline lens undergoing posterior chamber sutureless implantation of an IOL were studied. The haptics of the IOL were externalized using two 25-gauge forceps. The haptics were bended back (hook-like) into the vitreous cavity through a scleral incision made by using a 25-gauge trocar. And, IOL tilt was determined by using a slit lamp and UBM, and complications were recorded.
The IOLs were fixed with exact centration and axial stability. No wound leakage was reported even without the use of sutures. The mean best-corrected visual acuity (BCVA) was 0.82 logarithm of the minimum angle of resolution (logMAR) units preoperatively, and the mean BCVA was 0.44 logMAR units at the 6-month follow-up visit. No postoperative retinal detachment, endophthalmitis, IOL tilt or dislocation, or vitreous hemorrhage was noted.
Sutureless intrascleral haptic-hook posterior chamber IOL implantation using 25-gauge trocars provides good IOL fixation with reliable wound closure without the use of sutures. This trial is registered with ChiCTR1800017436.
报告一种使用25G套管针进行三片式可折叠人工晶状体(IOL)无缝线巩膜内固定的新技术。
我们对后囊支持不足的患者实施了该技术。研究了15例无晶状体眼、人工晶状体脱位或晶状体半脱位患者的17只眼,这些患者接受了后房型人工晶状体无缝线植入术。使用两把25G镊子将人工晶状体的襻引出眼外。通过使用25G套管针制作的巩膜切口将襻向后弯曲(呈钩状)送入玻璃体腔。并且,使用裂隙灯和超声生物显微镜(UBM)确定人工晶状体的倾斜度,并记录并发症。
人工晶状体固定中心准确且轴向稳定。即使不使用缝线也未报告伤口渗漏。术前平均最佳矫正视力(BCVA)为0.82最小分辨角对数(logMAR)单位,随访6个月时平均BCVA为0.44 logMAR单位。未观察到术后视网膜脱离、眼内炎、人工晶状体倾斜或脱位或玻璃体出血。
使用25G套管针进行无缝线巩膜襻钩状后房型人工晶状体植入术可实现良好的人工晶状体固定,且无需缝线即可可靠地闭合伤口。本试验在中国临床试验注册中心注册,注册号为ChiCTR1800017436。
