Lacrimal duct occlusion for the treatment of dry eye

Abstract

The most widespread treatment for dry eyes in clinical practice is an instillation containing artificial tear fluid. When an instillation does not ameliorate dry eye, we use punctal plugs. The insertion of punctal plugs is an eminent curative that positively improves the corneal and conjunctival epithelial disorders and the amount of lacrimal fluid accumulated in the conjunctival sac. We shall introduce the lacrimal duct occlusion utilizing atelocollagen solutions, which solves many of the issues induced by conventional methods.
