The COVID-19 pandemic has increased the need for innovation in ophthalmic medical education, and surgical videos are an important part of the solution. They are already used at just about every congress and seminar to share information with and demonstrate techniques to colleagues. Presentations can be easily supported by prerecorded or live-streamed surgical videos. The advantage of the latter is that attendees can be permitted to ask questions and can watch techniques as they are being performed in real time. Revolutionary!
As a lifelong student and longtime speaker and teacher, I find surgical videos to be the most effective vehicle for delivering medical education. The materials published online by my colleagues in the United States and Europe are valuable, but I noticed a lack of content coming out of Latin America. The problem, I soon realized, is a lack of access to the costly recording technologies available in other countries. I decided to search for an alternative, less expensive method to record surgical videos so that more surgeons can share their expertise.
FINDING AN ALTERNATIVE
Many of the alternatives for recording live surgery in the OR require an external drive, a technician for setup, and a tedious process of extracting the files and accessing them from other computers. Several methods and devices that facilitate the recording of live surgery at an affordable price have been described in the literature. These include a variety of do-it-yourself approaches that repurpose smartphones or make use of consumer-grade cameras and video systems, or tripod mounts in addition to video capture/transfer devices and consumer video systems. (For a few examples, see Alternative Methods to Record Surgery.) My search led me to MicroRec (Custom Surgical; Figure 1), an optical system that can be attached to microscopic equipment and that can connect to the performant cameras of smartphones, facilitating the recording of live surgery at an affordable cost.
The MicroRec optical system can be installed quickly on any type of microscopic equipment. The device’s small size and light weight make it extremely portable. When I first started using it, I found that the entire dynamic of recording surgeries in my OR changed. Because a smartphone is both the recording and the storage medium with this system, I can record and upload surgical videos to the cloud quickly and edit them using apps on my phone.
After transitioning to this technology, I began using sequences of the videos I record during surgery in my presentations. When I share them on social media, these sequences receive considerable interest from viewers.
By taking advantage of a smartphone’s connectivity, the MicroRec optical system can be used to display live video on external screens via Chromecast or Apple TV (Figure 2). With the use of certain apps, live surgeries performed around the world could be incorporated into webinars.
I predict that surgical videos will be a major component of medical education for the duration of the current pandemic and quite possibly beyond.
