Abstract：
This study aimed to assess retinal alterations following membrane peeling procedures using novel ILM Forceps with laser ablated surface with the help of intraoperative optical coherence tomography (iOCT). A post-hoc analysis was performed to evaluate iOCT findings in eyes that underwent membrane peeling procedures with the novel ILM Forceps. Pre-peel and post-peel iOCT videos and images were evaluated for each eye to assess for post-peel anatomic alterations. Surgical video/iOCT scan correlation was conducted to evaluate the etiology of anatomic alterations. Thirty-two eyes were included in the analysis. Three eyes (9%) had focal full thickness retinal elevations identified on iOCT following tissue-instrument interaction with the ILM Forceps. Two eyes (6%) had focal inner retinal elevations and one eye (3%) had a full-thickness retinal elevation that were not related to direct tissue-instrument interaction but rather indirect peeling forces. iOCT-identified architectural alterations related to direct-tissue instrument interaction were relatively infrequent (< 10%) with similar frequency to previously reported alterations with other surgical instruments.
摘要：
本研究旨在在术中光学相干断层扫描（iOCT）的帮助下，使用具有激光烧蚀表面的新型ILM镊子评估膜剥离手术后的视网膜变化。进行了事后分析，以评估使用新型ILM镊子进行膜剥离手术的眼睛中的iOCT发现。评估每只眼睛的剥离前和剥离后iOCT视频和图像以评估剥离后解剖改变。进行手术视频/iOCT扫描相关性以评估解剖改变的病因。分析中包括32只眼。在与ILM镊子的组织-仪器相互作用后，在iOCT上发现了三只眼（9％）的局灶性全厚度视网膜抬高。两只眼睛（6％）具有局灶性内部视网膜抬高，一只眼睛（3％）具有全厚度视网膜抬高，这与直接的组织-仪器相互作用无关，而是与间接剥离力有关。iOCT鉴定的与直接-组织器械相互作用相关的结构改变相对罕见（<10%），其频率与先前报道的其他手术器械改变的频率相似。
