Study summary

The objective of this study is to evaluate the clinical performance of the STAAR EVO+ Visian™ Implantable Collamer® Lens with Aspheric (EDOF) Optic as refractive elements to correct or reduce myopia or hyperopia with presbyopia with or without astigmatism.

Read the detailed description

This prospective, open-labeled, evaluation of clinical performance of the investigational EDOF and Toric EDOF (TEDOF) ICL will be conducted at a single site in the Philippines.

Up to 45-50 subjects (90 eyes) who meet all eligibility criteria will be assigned to one of the following treatment arms, as determined by their preoperative refraction and the Investigator's medical judgement:

  • EDOF Toric ICL in both eyes,
  • EDOF Toric ICL in one eye and EDOF spherical ICL in fellow eye,
  • EDOF spherical ICL in both eyes (up to 20 subjects/40 eyes).

Postoperatively, subjects will undergo ophthalmic examination at regular intervals per the study visit schedule up to 6 months after surgery.

  • Requires +1.00 Diopters to +2.50 Diopters reading add in both eyes.
  • Minimum distance corrected near visual acuity of 20/40 or worse in both eyes.
  • Other protocol-specified inclusion criteria may apply.

What researchers measure

Primary outcomes

  1. Change in visual acuity

    Change from baseline in uncorrected distance, intermediate and near visual acuity and distance corrected near visual acuity

    Time frame: 1 month, 3 months and 6 months postoperatively

  2. Change in refractive cylinder

    Change from baseline in absolute magnitude of subjective refractive cylinder

    Time frame: 1 month, 3 months and 6 months postoperatively

  3. Lens axis misalignment

    Proportion of lenses with axis misalignment compared to operative day

    Time frame: 1 month, 3 months and 6 months postoperatively

  4. Rotational stability

    Rotational stability by assessment of IOL axis meridian compared to placement on day of surgery

    Time frame: 1 day, 1, week, 1 month, 3 months and 6 months postoperatively

  5. Compromise in visual acuity

    Clinically significant compromise in visual acuity based on subject questionnaires

    Time frame: 6 months postoperatively

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2022 to primary completion in Oct 2024, 25 months.

Of 234 industry-sponsored interventional studies with no phase under Myopia, half reached primary completion within 6 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 24. This study's 25 months is above that.

Counting every sponsor, half of 434 studies reached it within 14 months; a quarter within 3 and three quarters within 34.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 18, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
