目的探讨结膜下环线固定植入后房折叠型人工晶状体临床疗效。方法选择就诊于郑州市第二人民医院的无晶状体眼患者38例(38眼),眼外伤引起:29例;继发于白内障术中后囊破裂9例。患者均为Ⅰ期手术后3～6个月,散瞳检查无连续存在的残存后囊。固定缝线从角膜缘后2.5mm3、9点区进出。上方3.2mm透明角膜切口入前房,引出固定缝线固定晶状体两襻,晶状体折叠后植入后房。纵行剪开上方球结膜,沿角膜缘结膜下钝性分离至固定缝线位置,结膜下勾出两端固定缝线并结扎。术后应用典必殊眼水及散瞳剂治疗。观察角膜及晶状体情况,随访6个月。结果术后第1、3、7天观察,所有患者角膜透明,晶状体位置稳定。1例患者术后7天发现结膜下缝线断裂,晶状体位置无移动,随访6个月未见变化。术后平均视力(0.35±0.23),与术前相比差异有统计学意义。结论结膜下环线固定植入折叠型人工晶状体可以明显缩短手术时间,减轻眼内炎症反应,加速术后伤口愈合,减少术中及术后并发症的出现。
Objective To investigate the clinical effect of subconjunctival loop fixation of posterior chamber foldable intraocular lens implantation. Methods Thirty-eight patients (38 eyes) with aphakia who were seen at the Second People’s Hospital of Zhengzhou City were selected. Ocular trauma was caused by 29 cases and posterior capsule rupture was caused by cataract surgery in 9 cases. Patients were stage Ⅰ 3 to 6 months after surgery, dilated examination without residual persistence of the posterior capsule. Fixed suture from the corneal edge after 2.5mm3, 9 points out. The top 3.2mm clear corneal incision into the anterior chamber, lead to fixed suture fixation of the two lenses, the lens folded after implantation of the posterior chamber. Longitudinal cut the bulb above the conjunctiva, along the limbal conjunctival blunt dissection to a fixed suture position, under the conjunctiva hooked at both ends of the fixed suture and ligation. After the application of the code must be special eye water and mydriatic treatment. Corneal and lens observation, follow-up 6 months. Results The first, third and seventh day after operation, all the corneas were transparent and the lens position was stable. One patient was found to have a subconjunctival suture rupture 7 days postoperatively with no movement of the lens and no change at 6 months of follow-up. The average postoperative visual acuity (0.35 ± 0.23), compared with the preoperative difference was statistically significant. CONCLUSION: Folding intraocular lens with subconjunctival loop fixation can significantly shorten the operation time, reduce intraocular inflammation, accelerate wound healing and reduce the occurrence of intraoperative and postoperative complications.
