Visible-light optical coherence tomography imaging-driven 3D printing of customized contact lens

The development of visible-light optical coherence tomography (vis-OCT) has revolutionized the precision in measuring 3D anatomic features. When combined with 3D printing, which efficiently converts digital models into tangible objects, both technologies achieve micron-scale resolution. This synergy opens new avenues in designing and creating custom biomedical devices tailored to individual patients. For instance, in the case of contact lenses, vis-OCT is utilized to accurately map the corneal surface topology. This mapping informs the design of the contact lens's inner surface, ensuring an optimal fit. Subsequently, these personalized contact lens designs are produced using advanced, high-resolution 3D printing techniques. Both the fit and optical performance of these 3D-printed contact lenses have been thoroughly tested and validated experimentally
