Abstract

Background: To assess anatomical and functional outcomes of retrolental cohesive ophthalmic viscoelastic injection ("Viscolift technique") in patients with severely subluxated cataracts.

Methods: In the present prospective study, we included patients older than 18 years with severely subluxated cataracts and phacodonesis. Full medical history was obtained at the baseline ophthalmological assessment. A single 25-gauge valved trocar was inserted 4 mm from the limbus and a 27G angled cannula was introduced through the trocar into the retrolental space, while cohesive viscoelastic was progressively injected, in order to center and elevate the cataract to facilitate capsulorhexis. After complete phacoemulsification, a 3-piece intraocular lens (IOL) with a scleral fixated Cionni ring or FIL-SSF scleral fixated IOL was implanted. Patients follow-up interval was 6 months after surgery.

Results: Thirteen eyes of 13 patients were enrolled in the study, mean age was 61.5 ± 9.4 years and 53.8% were females. The "Viscolift technique" resulted in centered and more stable cataracts in all cases (100%). After complete phacoemulsification, 61.5% of patients were implanted with a 3-piece IOL with Cionni ring, and 38.5% with a FIL-SSF scleral fixated IOL after complete 25G vitrectomy. Mean BCVA improved from 0.5 ± 0.1 LogMar (20/63 Snellen) to 0.1 ± 0.1 LogMar (20/25 Snellen) (p < 0.001) at the last follow-up. No major complications were noted.

Conclusions: The "Viscolift technique" proved to be a safe and effective surgical approach for recentering and elevating subluxated cataracts, thus allowing the surgeon to perform an easier and better-centered capsulorhexis.

视网膜凝聚性眼科粘弹性注射治疗严重下垂性白内障:一项前瞻性研究。
背景:目的:评估对严重白内障患者进行后牙龈粘弹性注射("Viscolift 技术")的解剖和功能效果:目的:评估严重下陷性白内障患者接受后牙合眼科粘弹性注射("Viscolift 技术")的解剖和功能效果:在这项前瞻性研究中,我们纳入了 18 岁以上患有严重下陷性白内障和噬骨症的患者。在进行基线眼科评估时,我们了解了患者的全部病史。在距眼球边缘 4 毫米处插入单个 25 号瓣膜套管,通过套管将 27G 角套管导入齿后间隙,同时逐步注入粘性粘弹剂,使白内障居中并抬高,以利于囊外摘除。完成乳化手术后,植入带有巩膜固定Cionni环或FIL-SSF巩膜固定人工晶体(IOL)的3片式人工晶体。患者的随访间隔为术后 6 个月:13名患者的13只眼睛参加了研究,平均年龄为(61.5 ± 9.4)岁,53.8%为女性。所有病例(100%)都采用了 "Viscolift 技术",术后白内障的位置更集中、更稳定。在完成乳化手术后,61.5% 的患者植入了带 Cionni 环的三片式人工晶体,38.5% 的患者在完成 25G 玻璃体切除术后植入了 FIL-SSF 巩膜固定人工晶体。平均 BCVA 从 0.5 ± 0.1 LogMar(20/63 Snellen)提高到 0.1 ± 0.1 LogMar(20/25 Snellen)(p 结论:"Viscolift 技术 "是一种有效的治疗方法:事实证明,"Viscolift 技术 "是一种安全有效的手术方法,可用于重新定位和升高半脱位白内障,从而使外科医生能够更轻松、更准确地进行囊外摘除术。
