Not at the large scale - there aren't really any refracting telescopes left (based on lenses) when it comes to serious research, we replaced them with reflecting telescopes instead (based on mirrors). There's a few notable exceptions, like the Lick Observatory, but in terms of impacting the state or progress of astronomy, the research from this article is unlikely to have an impact outside of small scale labs and amateur astronomy. That's not to say the benefits there won't be appreciable for those who rely on optical telescopes, but you won't see this research make a difference for ground based arrays like NRAO, VLA, or in space telescopes.
