Ocular Medical Devices: Histologic Technique and Histopathologic Evaluation of the Biocompatibility and Performance

Ocular medical devices (MDs) represent a very wide and promising field of human ophthalmology. In preclinical studies evaluating the safety and/or performance of these ocular MDs, the choice of histologic technique and the focus of the histopathologic evaluation method should take into consideration the following aspects: the specific guidelines possibly associated with the MD or combination product, the ocular compartment in contact with the MD and its specificities, and last the nature of the biomaterial used in the MD. Following a brief overview of animal models, this short review will present the different types of ocular MDs and will present the specificities of the histologic technique and the histopathologic evaluation related to ocular MDs
