The Zeiss Lenstar Myopia is a state-of-the-art, non-contact device that measures axial length—the length of the eye from front to back—which is a key indicator in monitoring myopia progression. Unlike standard handheld tools that touch the eye and can vary in accuracy, the Lenstar uses light-based technology to deliver highly precise and repeatable measurements without any discomfort. Tracking axial length helps us detect early signs of myopia progression more reliably than simply monitoring prescription changes alone, allowing for more effective and personalized treatment to protect longterm vision.
