Rodenstock unveiled its B.I.G. Exact Sensitive lenses, which take into account individual visual sensitivity, at 100% Optical (1–3 March).
The new launch builds on Rodenstock’s B.I.G. Exact lenses, which are designed using the biometrics of the patient’s eye.
Suggesting that the new lens marks “the next level of personalisation,” Jason Halsey, product and training manager for Rodenstock UK, explained: "Every eye is different but even two biometrically similar eyes might perceive aberrations in a very different way. Visual sensitivity is trying to measure and address that.”
More than five years of research has gone into designing the lens. Halsey shared that Dr Alexandra Sipatchin, a neuroscientist and global product manager at Rodenstock explored: “aberrations and how we work with them, to give the brain the best input.”
Describing the different degrees of sensitivity patients might have in their vision, he said: “We can now measure that sensitivity and incorporate that into the design to give them a more perceived bespoke experience.”
For practices that already have a DNEye scanner from Rodenstock, which takes a complete biometric measurement of a patient’s eye, practitioners will only need to add the patient’s visual acuity.
The lens takes into account pupillometry, aberrometry, biometry, as well as visual acuity of the patient.
“Utilising that data we then get a sensitivity index and we can map where the patient will be and adjust the design based on that. So, the patient gets the best visual experience for their brain, rather than just for their eyes,” Halsey said.
