To evaluate the potential value of microscope-integrated optical coherence tomography (MI-OCT) in anterior segment surgical maneuvers.
Twenty-four ophthalmology residents, who were randomly and evenly divided into two groups, performed four anterior segment surgical maneuvers (corneal tunnel, scleral tunnel, simple corneal suture, and corneal laceration repair) on porcine eyes with (group B) or without (group A) real-time MI-OCT feedback. All residents performed the maneuvers again without MI-OCT.
Compared with group A, group B (with MI-OCT) showed better accuracy in the length/depth of the corneal tunnel and the length of the scleral tunnel. However, both groups showed similar performances in the depth of both the simple corneal suture and the corneal laceration suture. When both groups performed the maneuvers again without MI-OCT, group B still showed better results than group A for the length of both the corneal and scleral tunnels.
Primary results suggest that real-time MI-OCT images are valuable for some anterior segment surgical maneuvers and could be helpful in surgical training.
MI-OCT systems can be valuable in improving accuracy and decision making during anterior segment surgery and will be useful in surgical training.
评估显微镜集成光学相干断层扫描（MI-OCT）在前节手术操作中的潜在价值。
24名眼科住院医师被随机平均分为两组，分别在有（B组）或无（A组）实时MI-OCT反馈的情况下，对猪眼进行四项前节手术操作（角膜隧道、巩膜隧道、单纯角膜缝合和角膜裂伤修复）。所有住院医师在无MI-OCT的情况下再次进行这些操作。
与A组相比，B组（有MI-OCT）在角膜隧道的长度/深度和巩膜隧道的长度方面显示出更高的准确性。然而，两组在单纯角膜缝合和角膜裂伤缝合的深度方面表现相似。当两组在无MI-OCT的情况下再次进行操作时，B组在角膜和巩膜隧道长度方面仍比A组表现更好。
初步结果表明，实时MI-OCT图像对某些前节手术操作有价值，并且可能有助于手术训练。
MI-OCT系统在提高前节手术的准确性和决策方面可能有价值，并且将有助于手术训练。
