Sinclair is a revolting person, with little professional dignity, who shamelessly manipulates his audience in interviews, spreading misleading scientific information, out of desperation to promote his personal brand.
Absolutely not. He is piggy-backing on the landmark work by other groups; he just re-applied it to the eye organ. The doxycyclin-based approach which this kind of studies are using can't be translated for clinical application in humans and in general partial reprogramming carries the risk of teratomas. So contrary to that tweet, it won't be ready for the clinic for years, decades, maybe never.
