Microneedles (MNs) are an innovative and minimally invasive approach to ocular drug delivery. Unlike traditional methods such as eye drops or injections, MNs can directly target specific eye tissues, including the cornea and retina, allowing for more effective treatment and improved patient comfort. This review highlights recent advances in MN technology, including 3D printing for customized geometries and the use of smart materials for sustained and controlled drug release. These innovations underscore the potential of MNs to transform treatment strategies for chronic eye diseases.
