The Types segment classifies punctal plugs according to material composition, which directly influences insertion technique, biocompatibility, and dwell time. Three material families dominate: collagen, silicone, and hydrogel. Collagen plugs are absorbable, typically lasting 4–6 weeks, and are favored in short‑term dry‑eye therapy; they contribute approximately 40 % of unit sales due to their low cost and ease of removal. Silicone plugs are non‑absorbable, offering long‑term occlusion up to several years, and dominate the chronic‑care market, representing about 45 % of revenue because of higher pricing and repeat‑procedure demand. Hydrogel plugs provide a middle ground with semi‑permanent occlusion and enhanced patient comfort, capturing roughly 15 % of the market. Each type addresses distinct clinical needs, and their combined performance underpins the overall market valuation, reinforcing the relevance of material‑based taxonomy in Punctal Plug Devices segmentation.
