We report a novel technique characterized by sutureless scleral fixation of three-pieces foldable intraocular lens (IOL) using 25-gauge transconjunctival sutureless vitrectomy (TSV) trocars in patients with insufficient posterior capsule support.
We performed this technique on the eight eyes of the seven patients. The scleral tunnels (STs) are prepared by insertion of the 25-gauge TSV microcannulas using the trocars, and anterior vitrectomy is performed through the clear corneal paracentesis with the aid of anterior chamber maintainer (ACM). Finally, the three-piece foldable IOL haptics are incarcerated into the prepared STs.
The patients were followed up 5-8 months. None of the patients had complications such as postoperative endophthalmitis, glaucoma, IOL tilt or decentralization, and retinal detachment. Injection of a foldable IOL through a clear corneal small incision also contributes the less surgical-induced astigmatism.
The presented novel sutureless scleral IOL fixation technique may provide minimal trauma to the surrounding tissues, good IOL stabilization decreasing the incidence of IOL tilt along with shorter operation time, and postoperative quiet eye.
我们报告了一种新的技术，该技术采用 25G 经结膜无缝线玻璃体切割（TSV）套管针，对后囊膜支持不足的患者进行无缝线巩膜固定三片式折叠式人工晶状体（IOL）。
我们对 7 名患者的 8 只眼进行了这项技术。通过套管针插入 25G TSV 微套管来制备巩膜隧道（ST），并通过前房维持器（ACM）在前角膜穿刺口进行前玻璃体切割。最后，将三片式折叠人工晶状体襻固定到准备好的 ST 中。
患者随访 5-8 个月。所有患者均无术后眼内炎、青光眼、IOL 倾斜或偏心、视网膜脱离等并发症。通过小切口透明角膜注射折叠式 IOL 也有助于减少手术引起的散光。
所提出的新型无缝线巩膜 IOL 固定技术可能对周围组织造成最小的创伤，良好的 IOL 稳定性降低 IOL 倾斜的发生率，手术时间更短，术后安静的眼睛。
