We put forward a physical levitation method to hook and flip the chopped nuclear fragments that could not be solely drawn by vacuum during phacoemulsification, due to various reasons such as a non-rotating nuclei or posterior polar cataracts where hydrodissection was unsuccessful or contra-indicated, respectively.
A Sinskey hook is insinuated through the crack of the divided nuclei into a plane behind the nuclear pie to 'hook and flip' the chopped piece, heading it towards the phacoemulsification probe. This simple step disassembles the nuclear chunk, thereby creating space to facilitate the dismantling of the rest of the fragments. The remnant epinuclear cushion guards the posterior capsule, mitigating the chances of serious intra-operative complications.
We have employed this technique in 17 eyes during similar situations. No specific intra-operative complications were observed; all surgeries were uneventful. A Sinskey hook utilised for this step ensures safety and familiarity, none encountered posterior capsular rent. This technique not only eases the surgery, but also decreases the anticipated intra-operative and post-operative complications.
'Hook and flip technique' thus proves useful whenever dismantling difficulties are encountered during phacoemulsification.
我们提出一种物理悬浮方法,用于在超声乳化过程中钩住并翻转因各种原因(如核不旋转或后极性白内障,分别导致水分离不成功或禁忌)而无法仅通过真空吸出的切碎核碎片。
将辛斯基钩通过分裂核的裂缝插入核块后面的平面,以“钩住并翻转”切碎的碎片,使其朝向超声乳化探头。这一简单步骤可拆解核块,从而创造空间以利于拆解其余碎片。残留的核上皮质保护后囊,降低严重术中并发症的发生几率。
我们在类似情况下对17只眼采用了该技术。未观察到特定的术中并发症;所有手术均顺利进行。用于该步骤的辛斯基钩确保了安全性和操作的熟练度,未出现后囊破裂情况。该技术不仅简化了手术,还减少了预期的术中及术后并发症。
因此,“钩翻技术”在超声乳化过程中遇到拆解困难时被证明是有用的。
