摘要：
Surface treated implantable articles and related methods are disclosed. The surface treated implantable articles can be substantially flash-free, include one or more rounded edges, or include an enhanced optical clarity, one or all of which can be produced by polishing. The polishing can include causing the implantable articles to be repeatedly impacted with polishing media when the articles are swelled to an enlarged state. The polishing process can be particularly useful for smoothing lacrimal implants insertable in a lacrimal canaliculus.
