331 of the 331 trials are tagged with Presbyopia itself; the rest are tagged with a narrower condition beneath it.
When did Presbyopia trials start? (23)
Shown in this order: most recent first, 1990 onwards. 2026 is partial: trials registered with a 2026 start date so far, not a full year.
Trials over time, by phase
- Phase 1
- Phase 1/2

Top of scale: 34
Trials registered with a start date in each year, 1990 onward, stacked by phase (complete years only; the current partial year is in the table's notes). The table below lists the same counts, most recent years first.
| Year | Trials started |
|---|---|
| 2026 (partial year) | 10 |
| 2025 | 23 |
| 2024 | 22 |
| 2023 | 22 |
| 2022 | 34 |
| 2021 | 24 |
| 2020 | 25 |
| 2019 | 20 |
| 2018 | 24 |
| 2017 | 23 |
Showing 10 of 23 earlier years.
Forecast of the full-year count, planned starts included, not rows of this table: about 14 trials starting in 2026 and about 17 in 2027, the average of the 24 months through September, counted as registered and carried forward, with about 0.7 times the starts already registered for the rest of 2026 added. The rows of this table count trials registered so far with a start date in the year, planned starts included; the forecast looks ahead to the count for the whole year, so it is not the same measure. In backtests on conditions of this size, forecasts made part-way through the year were typically off by about 15 percent and ran about 1 percent high against the count later registered; forecasts made before the year began were off by about 26 percent and ran about 20 percent low against the count later registered. The part-way figures are from forecasts that used a multiple fitted only on earlier years. These figures rest on a few years of history (target years from 2018 to 2025, varying by figure), place each condition as it is mapped today rather than as it was then, and score against a count for the newest year that was still being revised. Only condition series were scored.
Prediction, not a registry value: median of 21 months from start to primary completion across 13 trials still running at the 2026-10-09 snapshot; registered median of 9 months across 252 trials with a primary completion typed Actual. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Presbyopia trials? (13)
Shown in this order: most trials first. Lead sponsors the registry classes as industry, NIH, US federal, other government or network. A hospital or university the registry files as government can appear here. Sponsors it classes as academic or other are shown on the full page, because that class cannot separate an institution from a named investigator.
| Sponsor | Trials |
|---|---|
| Alcon Research | 36 |
| CooperVision, Inc. | 16 |
| AcuFocus, Inc. | 11 |
| Beaver-Visitec International, Inc. | 10 |
| CIBA VISION | 9 |
Showing 5 of 13 sponsors.
Which drugs are being tested for Presbyopia? (1)
Shown in this order: most trials first. One row per drug, matched to a single molecule under all its names, ranked by number of trials.
| Drug | Trials |

| Brimonidine | 3 |
Interventions as named in the registry (14)
Shown in this order: most trials first.
| Drug | Trials |

These are the names sponsors entered on ClinicalTrials.gov that we have not matched to a single molecule. Some are drugs under a brand or code name; others are procedures, doses or arm labels.
Which serious adverse events do Presbyopia trials report? (10)
Shown in this order: most subjects affected first. Subjects affected summed across trials, a cross-trial signal, not a rate.
