To assess anatomical and functional outcomes of retrolental cohesive ophthalmic viscoelastic injection ("Viscolift technique") in patients with severely subluxated cataracts.
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.
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.
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.
评估晶状体后粘性眼科粘弹性注射（“Viscolift技术”）在严重半脱位白内障患者中的解剖学和功能结果。
在本前瞻性研究中，我们纳入了年龄超过18岁、患有严重半脱位白内障和晶状体震颤的患者。在基线眼科评估时获取完整的病史。将一根25号带阀套管针插入距角膜缘4毫米处，并通过套管针将一根27G弯形套管引入晶状体后间隙，同时逐步注入粘性粘弹性物质，以使白内障居中并抬高，便于连续环形撕囊。在完成超声乳化后，植入带有巩膜固定Cionni环的三件式人工晶状体（IOL）或FIL-SSF巩膜固定IOL。患者术后随访间隔为6个月。
13例患者的13只眼纳入研究，平均年龄为61.5±9.4岁，53.8%为女性。“Viscolift技术”在所有病例（100%）中均使白内障居中且更稳定。在完成超声乳化后，61.5%的患者植入了带有Cionni环的三件式IOL，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IOL。末次随访时平均最佳矫正视力（BCVA）从0.5±0.1 LogMar（20/63 Snellen）提高到0.1±0.1 LogMar（20/25 Snellen）（p<0.001）。未观察到重大并发症。
“Viscolift技术”被证明是一种安全有效的手术方法，可使半脱位白内障复位并抬高，从而使手术医生能够更轻松地进行更好居中的连续环形撕囊。
