Among 20 million cataract surgeries being performed worldwide every year, approximately 5% are being complicated by posterior capsule rent or zonular dialysis. Intraocular lens (IOL) implantation in such cases with intraoperative complications is quite challenging. Our next course of action is to place the IOL in the ciliary sulcus, however, there is a risk of IOL drop into the vitreous in cases of inadequate support. We have described a novel idea of using a suture material through the dialling hole of a three-piece rigid IOL which can be used as a leash to reduce the risk of IOL drop during implantation in such cases. This technique could also be used during sutureless scleral fixated IOL and retro-pupillary iris claw lens implantation. We found that in 90 consecutive patients where this technique was used, there was no incidence of IOL drop or retinal detachment.
在全球每年进行的2000万例白内障手术中,约5%会并发后囊膜破裂或悬韧带离断。在术中出现此类并发症的情况下植入人工晶状体(IOL)极具挑战性。我们接下来的做法是将IOL植入睫状沟,但在支撑不足的情况下存在IOL坠入玻璃体的风险。我们描述了一种新颖的想法,即通过三片式硬性IOL的拨孔使用缝线材料,该材料可作为牵引线以降低此类情况下植入IOL时坠入的风险。该技术也可用于无缝线巩膜固定IOL和瞳孔后虹膜夹晶状体植入。我们发现,在连续90例使用该技术的患者中,没有发生IOL坠入或视网膜脱离的情况。
