摘要

The literature review analyzes the most commonly used drains (collagen, metal, synthetic polymer based, and biopolymer) based on their main characteristics: biocompatibility, bio-resorption, possibilities of the saturation with the drug substances, abilities to a transportation of aqueous humor, and in case of non-penetrating deep sclerectomy a?? to a maintenance of a volume of intrascleral cavity. A special attention was paid to aspects and mechanisms of bio-resorption drainage implants.
