To describe the initial surgical experience and report the safety and feasibility of dry pars plana capsulotomy and anterior vitrectomy using a 25-gauge vitrectomy system in pediatric cataract surgery.
This was a prospective case series study. After anterior continuous curvilinear capsulorhexis (ACCC) and phacoemulsification with intraocular lens (IOL) implantation in the capsule for all patients, a pars plana capsulotomy and anterior vitrectomy was performed with a 25-gauge vitrectomy system using a dry technique in 40 eyes of 30 children with cataracts.
All procedures were uneventful and all IOLs were implanted in the capsular bag. No intraoperative complications were noted attributable to the small-gauge instruments. The average follow-up period was eight months (range, 4 to 30). Postoperative intraocular pressure remained stable in most cases, except two eyes (5%) with transient hypotony during the first day after surgery. The postoperative inflammatory response was mild. Ultrasound biomicroscopy showed complete healing of the sclerotomy at four weeks after surgery. No posterior synechia, posterior capsule opacification, IOL capture, vitreous prolapse, choroidal detachment or retinal detachment was observed throughout the follow-up period.
Dry pars plana capsulotomy and anterior vitrectomy using a 25-gauge vitrectomy system is safe and effective for the management of posterior lens capsules and anterior vitreous in pediatric cataract surgery. Prospective and comparative study is recommended to evaluate this procedure and traditional method.
描述初次手术经验,并报告在儿童白内障手术中使用25G玻璃体切割系统进行干法平坦部囊切开术和前部玻璃体切除术的安全性和可行性。
这是一项前瞻性病例系列研究。所有患者均先行前囊连续环形撕囊(ACCC)及晶状体超声乳化吸除联合囊袋内人工晶状体(IOL)植入术,之后对30例患有白内障的儿童的40只眼,使用25G玻璃体切割系统采用干法技术进行平坦部囊切开术和前部玻璃体切除术。
所有手术均顺利完成,所有人工晶状体均植入囊袋内。未发现因小口径器械导致的术中并发症。平均随访期为8个月(范围4至30个月)。大多数病例术后眼压保持稳定,除了2只眼(5%)在术后第一天出现短暂性低眼压。术后炎症反应较轻。超声生物显微镜检查显示术后4周巩膜切口完全愈合。在整个随访期间未观察到后粘连、后囊膜混浊、人工晶状体夹持、玻璃体脱出、脉络膜脱离或视网膜脱离。
在儿童白内障手术中,使用25G玻璃体切割系统进行干法平坦部囊切开术和前部玻璃体切除术对于处理晶状体后囊膜和前部玻璃体是安全有效的。建议进行前瞻性对比研究以评估该手术方法和传统方法。
