Punctal plug insertion is a simple, effective, safe, and reversible method to treat aqueous tear deficiency and other ocular surface diseases, such as epitheliopathy after penetrating keratoplasty, superior limbic keratoconjunctivitis, neurotrophic keratitis, recurrent corneal erosions, and toxic epitheliopathy not controlled by lubrication with preservative-free tears. However, spontaneous extrusion of silicone plug occurs commonly. Careful choosing of the optimal plug size and close follow-up are recommended to ensure the success of the treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
