Q&A: Phentolamine for presbyopia: a non-miotic route to near vision
The FDA approved phentolamine 0.75% (Ryzumvi, Opus Genetics/Viatris) for presbyopia in October 2026. The drug reduces pupil size via a sympatholytic mechanism, avoiding ciliary muscle engagement. Clinical trials showed 27.2% of patients gained near vision without losing distance vision. Experts discuss its unique mechanism and potential patient benefits compared to other presbyopia treatments.
