A new transparent, head-wearable display modeled after air fighter pilot technology aims to make ophthalmic surgery more precise.
“Using head gestures, the surgeon can shift between different virtual screens, and control functions such as focus and transparency transitions,” according to the Beyeonics website.
Other potential surgical applications described by Dr. Loewenstein included fluorescein imaging to aid with preplanning and reduced illumination that could help when treating epiretinal membrane, so there is less light toxicity.
At her center, she and fellow surgeons used the Beyeonics system for 25 cases. An additional 15 cases have been performed by Pravin Dugel, MD, Retina Consultants of Arizona, Phoenix.
Surgeries performed so far include vitrectomy, endolaser treatment, removal of lens fragments after cataract surgery, membrane peeling, internal limiting membrane (ILM) peel, retina detachment, and cataract.
Dr. Loewenstein described the transparent head-wearable display worn during surgery as lightweight. She also never experienced any imaging lag time during the surgeries she performed.
Other advantages of the system include good visualization and clarity, good field of view, and the ability to not be attached to the surgical microscope, according to Dr. Loewenstein. Although
Dr. Loewenstein was not aware of the cost of the technology, she said it may rival the price of a surgical microscope. When asked about the system’s learning curve, Dr. Loewenstein said she believes it is an easy system to learn, once the basics are established.
