To describe a new technique for transconjunctival intrascleral fixation of Cionni CTR using double-flanged polypropylens suture.
This is a prospective interventional case series which included 7 cases with severe (more than 180 degrees) zonular dialysis. Three cases were hereditary lens subluxation (Marfan syndrome), 2 cases with traumatic subluxation and 2 cases with pseudo-exfoliation syndrome.
All cases achieved a good postoperative stable and centered IOL with good visual results. No postoperative complications were recorded apart from PCO in 3 cases and mild bleeding during needle passage in one case.
This described technique is a simple, time sparing and minimally invasive method for achieving good bag centration. It eliminates the need of conjunctival peritomy, subconjunctival vessels cautery and scleral fashioning of a flap, pocket or a groove. The use of 6/0 polypropylene theoretically can achieve better longevity.
描述一种使用双凸缘聚丙烯缝线经结膜巩膜内固定Cionni人工晶状体睫状沟固定术(CTR)的新技术。
这是一个前瞻性干预性病例系列,包括7例严重(超过180度)晶状体悬韧带离断的病例。其中3例为遗传性晶状体半脱位(马凡综合征),2例为外伤性半脱位,2例为假性剥脱综合征。
所有病例术后人工晶状体均获得良好的稳定性且居中,视力恢复良好。除3例发生后囊膜混浊和1例穿刺时轻度出血外,未记录到其他术后并发症。
所述技术是一种实现人工晶状体良好囊袋居中性的简单、省时且微创的方法。它无需进行结膜切开、结膜下血管烧灼以及巩膜瓣、囊袋或沟的制作。理论上使用6/0聚丙烯缝线可获得更好的长期效果。
