Evaluation of intrastromal micropuncture in Eye Bank corneas using a tattoo machine.

The use of a tattoo machine represents a viable and accessible approach for keratopigmentation, with potential for both cosmetic and therapeutic applications. Its adaptation for controlled intrastromal drug delivery may enable the targeted treatment of deep infectious keratitis, corneal neovascularization, and stromal inflammatory disorders, representing a promising approach for corneal stromal diseases. Further research is needed to optimize techniques and evaluate long-term safety and efficacy, particularly for the delivery of antimicrobial, anti-inflammatory, and anti-vascular endothelial growth factor agents.
