We evaluated the potential utility of a cost-effective 4K consumer video system for surgical education in ophthalmology. Tokai University Hachioji Hospital, Tokyo, Japan. Experimental study. The eyes that underwent cataract surgery, glaucoma surgery, vitreoretinal surgery, or oculoplastic surgery between February 2016 and April 2016 were recorded with 17.2 million pixels using a high-definition digital video camera (LUMIX DMC-GH4, Panasonic, Japan) and with 0.41 million pixels using a conventional analog video camera (MKC-501, Ikegami, Japan). Motion pictures of two cases for each surgery type were evaluated and classified as having poor, normal, or excellent visibility. The 4K video system was easily installed by reading the instructions without technical expertise. The details of the surgical picture in the 4K system were highly improved over those of the conventional pictures, and the visual effects for surgical education were significantly improved. Motion pictures were stored for approximately 11 h with 512 GB SD memory. The total price of this system was USD 8000, which is a very low price compared with a commercial system. This 4K consumer camera was able to record and play back with high-definition surgical field visibility on the 4K monitor and is a low-cost, high-performing alternative for surgical facilities.
我们评估了一种经济高效的4K消费级视频系统在眼科手术教学中的潜在效用。日本东京东海大学八王子医院。实验研究。在2016年2月至2016年4月期间接受白内障手术、青光眼手术、玻璃体视网膜手术或眼部整形手术的眼睛，使用高清数字摄像机（LUMIX DMC-GH4，松下，日本）以1720万像素进行记录，同时使用传统模拟摄像机（MKC-501，池上，日本）以41万像素进行记录。对每种手术类型的两个病例的动态影像进行评估，并分类为可视性差、正常或极佳。4K视频系统通过阅读说明书即可轻松安装，无需专业技术知识。4K系统中手术画面的细节相比传统画面有了很大改进，手术教学的视觉效果显著提升。动态影像使用512GB SD存储卡可存储约11小时。该系统总价为8000美元，与商业系统相比价格非常低。这款4K消费级摄像机能够在4K显示器上以高清手术视野可视性进行录制和回放，是手术设施的一种低成本、高性能的替代选择。
