This work presents a novel approach to the fabrication of patient-specific hard contact lenses by combining DLP vat photopolymerization 3D printing with non-contact fluidization coating. The study demonstrates how advanced additive manufacturing and surface engineering can be leveraged to produce customized ophthalmic devices with excellent structural precision and biocompatibility.
𝐊𝐞𝐲 𝐡𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬:
✅ Patient-specific hard contact lenses designed using corneal topography-derived thickness maps.
✅ DLP 3D printing enables programmable thickness gradients for personalized lens fabrication.
✅ Non-contact fluidization coating provides a uniform and reliable surface modification.
✅ The fabricated lenses exhibit high oxygen permeability and excellent cytocompatibility.
✅ Confocal slicing and SEM characterization confirm precise fabrication of the intended thickness gradients.
This publication represents another step toward personalized medical devices through advanced manufacturing technologies.
