Topology’s Touchless Optical Platform (TOP) is a proprietary app that enables opticians to precisely measure patients, either in-store or at home, and ensure an exact fit of their eyeglasses. Every touchpoint that one would expect to receive in the optical dispensary is delivered in-person or virtually by opticians to their patients, according to Topology.

The San Francisco-based company first gained visibility in 2019, when it attracted the attention of the New Look Vision Group (http://www.newlookvision.ca/en/home.aspx). The Canada-based retail chain invested in Topology and received exclusive rights to retail its products in Canada and other selected markets. New Look’s Iris Visual Group then installed TOP in a number of its stores, allowing Topology to see how the system performed in an optical retail setting ahead of its U.S. launch in January, 2021.

“Topology is focused on both elevating the in-store experience for the optician and patient, as well as being able to deliver these services remotely,” Topology founder Eric Varady told the audience at Vision Monday’s 2020 Global Leadership Summit (https://www.visionmonday.com/scene-and-heard/todays-read/article/the-big-picture-trends-and-takeaways-from-vms-global-leadership-summit/). “It’s the tele-optical equivalent to the rise of refractive telemedicine. We’ve been working hand-in-hand with New Look Vision Group to focus on designing the interface and the product with the optician at the center of the experience, which I think is something that has never really been done before.”

The Touchless Optical Platform provides a complete and comprehensive optical experience to patients, virtually or when physically present in an eyecare practice. When combined with an optician’s know-how, TOP allows the practice to generate online sales and service patients remotely when necessary (lost or damaged glasses when travelling). It is designed for practices that wish to expand their frame offering without additional capital costs, raise levels of patient service and convenience, create individualized marketing programs driving incremental multipair revenue and integrate a tele-optical program.

Using state-of-the-art 3D digital technology currently found on an iPad or iPhone, patients can be scanned in an optical dispensary as part of the pre-test exam process, or remotely from their home. The scan takes less than one minute to complete. A full facial scan of over 20,000 reference points creates a digital mesh of each patients’ facial features, providing the optical staff everything needed to flawlessly fit stock frames and take all the optical measurements, even for the most complex prescriptions.

Topology’s TOP platform provides several unique benefits. The app preselects only frames in the user’s digital stock catalogue that will fit the patient’s facial features (i.e. bridge size and shape, width of the head and temple length). This eliminates significant time during the try-on and disinfecting process.

Each stock frame is digitally placed exactly how it will fit in real life on the patient’s face. Each time a different frame is selected, the TOP software adjusts all critical optical measurements to 1/100th of a millimeter, virtually, in real time, and specifically to each individual frame’s 3D position of wear. This includes monocular near and far PDs, OC heights, frame wrap, tilt, vertex distance and more. All optical measurements are provided for the lens manufacturing lab of choice. Once the final frame is selected, the app provides all the necessary frame adjustments, taking into account the base curve of the final Rx so the lab technician or optician can complete final adjustments without the patient being physically present. Topology recommends this for direct to home delivery or curbside pickup.

Zeiss Visufit 1000 is a digital platform with virtual try-on of frames in 3D. It is designed for ease of use with a computer or an iPad 6.

Patient measurement is performed without need of a clip-frame. 3D centration is achieved with nine mutually calibrated cameras that capture a 180° view of the patient’s face in a single shot without the need of a clip frame. The measurement data are processed using 45 million reference points, ensuring extremely precise capture of measurement data for the frame, the eye, the pupil and the cornea.

Back vertex distance can be determined for both sides, right and left. A 3D digital reconstruction of the face can be created and enables the back vertex distance to be captured, even with frames featuring very thick temples.

A virtual try-on module allows patients to explore catalogues of virtual frames. The system can create a patient avatar for trying out frames, allowing them to try on and compare frames in-store or use their digital twin to try on frames from an online catalogue. The virtual try-on module uses an artificial intelligence algorithm to learn from patient interactions. It analyses face shape, skin, eye and hair color to help dispensers suggest frames which best suit their patient.
