经结膜无缝合23G玻璃体切除术灌注系统在玻璃体切除术后白内障手术中的应用

Application of 23G transconjunctival sutureless vitrectomy irrigation system in surgery for post-vitrectomy cataract

回顾性分析30例(30只眼)均系玻璃体切除术后白内障的患者,经结膜无缝合23G玻璃体切除术(23G TSV)灌注系统的支持下行小切口非超声乳化白内障摘除术和白内障超声乳化术,观察视力预后、术中及术后并发症。1例患者在行超声乳化时,术中发现后囊膜破裂改行小切口手术。3例患者术后低眼压,其中1例发现是脉络膜脱离所致,另外2例考虑有切口的渗漏,经处理后恢复正常。4例硬核和3例合并糖尿病视网膜病变的患者术后出现角膜水肿和前房闪辉。所有患者没有出现巩膜塌陷、晶体核沉入玻璃体腔、脉络膜上腔出血等严重的并发症。28例患者术后视力得到改善。

A retrospective study included 30 cataract cases （30 eyes） with history of vitrectomy. Phacoemulsification or small incision non-phacoemulsification was performed with vitreous irrigation of 23G TSV. Observe the visual acuities, intraoperative and postoperative complications. Posterior capsule rupture intraoperatively occurred in one patient with phacoemulsification. Three patients suffered intraocular hypotension postoperatively, including one with choroidal detachment, and the other two probably with leakage from incisions. However, the intraoeular pressure rised to normal after treatment. Corneal edema and aqueous flare postoperatively occurred in four patients with hard nucleus cataract and three patients with diabetic retinopathy. There were no serious complications occurred in all patients, such as sclera collapse, nucleus sinking into vitreous chamber and bleeding in epichoroidal space. The visual acuities were improved after operation in twenty-eight patients.
