The aim of this study was to evaluate the outcome of the modified Carlevale intraocular lens (IOL) fixation technique, using two different vitrectomy ports (23- vs. 27-gauge) as anchor fixation.
Retrospective, consecutive study of 282 eyes (282 patients) who underwent a secondary IOL implantation using the Carlevale IOL (Soleko IOL Division, Italy) with two anchor haptics for intrascleral implantation with either 23- or 27-gauge (G) port.
Transient post-operative ocular hypotonia (intraocular pressure ≤5 mm Hg) was observed less in the 27-G group (13 vs. 4 patients, p = 0.057) three requiring additional tunnel sutures (2 cases for 23-G; 1 case 27-G). Post-operative vitreous haemorrhage was recorded more often in the 23-G group (8 vs. 1 patient, p = 0.034), but all cases in both groups resolved without intervention. Visual acuity did improve post-operatively in the two groups. No post-operative complications such as retinal detachment, endophthalmitis, and IOL-dislocation tilt were observed in the follow-up.
The 27-G modified technique for sutureless intrascleral implantation is simple and effective and causes less post-operative hypotony.
本研究旨在评估使用两种不同的玻璃体切割端口（23 号 vs. 27 号）作为锚定点固定改良的 Carlevale 人工晶状体（IOL）固定技术的结果。
回顾性连续研究 282 只眼（282 例患者），这些眼均接受了 Carlevale IOL（意大利 Soleko IOL 分部）的二次 IOL 植入术，使用两个锚定襻进行巩膜内植入，其中 23 号或 27 号（G）端口各 141 只眼。
27-G 组观察到的术后短暂性眼压低（眼压≤5mmHg）较少（13 例比 4 例，p=0.057），3 例需要额外的隧道缝线（23-G 组 2 例，27-G 组 1 例）。23-G 组术后玻璃体积血更为常见（8 例比 1 例，p=0.034），但两组所有病例均无需干预而自行吸收。两组术后视力均有所提高。在随访中，均未观察到视网膜脱离、眼内炎和 IOL 脱位倾斜等术后并发症。
无缝线巩膜内植入的 27-G 改良技术简单有效，术后眼压较低。
