Deep Dive
Is Qlosi the Next Game-Changer in Eyecare?
Qlosi (pilocarpine 0.4%) may be the most promising presbyopia drop yet.
In the NEAR-1 and NEAR-2 trials, 40.1% of patients achieved a ≥3-line improvement in near visual acuity in the study eye, compared to 19.1% with placebo. That gives us a Number Needed to Treat (NNT) of approximately 5.
Let’s pause on that. NNT is a simple but powerful metric: it tells us how many patients need to be treated for one to benefit. Remember, you calculate it as 1 ÷ Absolute Risk Reduction (ARR).
In this case:
1 ÷ (0.401 − 0.191) = ~5
That means, for every 5 patients given Qlosi, one additional person sees a meaningful clinical improvement compared to placebo.
This helps us move beyond statistical significance and into real-world expectations—something that matters when counseling patients and choosing treatment options.
For comparison, Vuity’s GEMINI 1 trial reported that 30.7% of patients achieved a ≥3-line gain in binocular near vision without ≥1-line loss at distance, compared to 8.1% in the placebo group. That gives us:
1 ÷ (0.307 − 0.081) = ~4.4
So, Vuity’s NNT is approximately 4–5, depending on the study, which puts it in a similar efficacy range to Qlosi.
But there's a nuance worth noting: Qlosi’s results are monocular, while Vuity’s (from GEMINI and VIRGO) were binocular.
That makes direct comparisons tricky, especially when evaluating functional visual outcomes in day-to-day life.
So is it a game-changer?
For some patients, perhaps. Lower concentration (0.4% vs. Vuity’s 1.25%) may reduce side effects. Onset is fast. Duration is decent. And if someone is motivated to avoid readers for specific tasks, Qlosi might be the right tool.
But like any tool, its value depends on the context. This isn’t a replacement for progressive lenses, multifocal contacts, or refractive lens exchange—but it is a viable option we’re glad to have in the toolbox.
