Inclusion criteria

  • Willing to provide voluntary consent and able to comprehend and sign the form;
  • Pseudophakic patients implanted with an Acrylic (AcrySof®), PMMA or silicone IOL from 1994 to 2000;
  • Clear intraocular media in study eye;
  • Best-corrected visual acuity (decimal) within 3 months post-implantation of 0.8 (decimal VA chart) or more in study eye;
  • No ocular or systemic condition which may affect visual acuity in study eye;
  • Other protocol-specified inclusion criteria may apply.

Exclusion criteria

Exclusion Criteria:

  • Complications that may impact visual acuity in study eye at the time of the prospective visit, such as glaucoma, diabetic retinitis, ocular inflammatory disease, retinal detachment, and others as specified in the protocol;
  • Previous refractive surgery in study eye;
  • Previous IOL exchange in study eye;
  • Other protocol-specified exclusion criteria may apply.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) at the Long-Term, Post-Implantation Visit

    Measurement of best corrected (with spectacles or other visual corrective devices) visual acuity (at both near and distance). Visual Acuity (VA) is measured in logMAR (logarithm of the minimum angle of resolution). A lower logMAR value indicates better visual acuity. One eye (study eye) contributed to the analysis.

    Time frame: Baseline (up to and including 3 months after implantation), long-term post-implantation visit (14-20 years after implantation)

Adverse events

Collected over Adverse events (AEs) were collected for the duration of a subject's participation in the study; retrospectively 14 to 20 years and prospectively for a single visit. This analysis group includes all subjects who used the study devices and underwent the long-term post-implantation visit examination. Ocular adverse events are presented for both study eye and non-study eye combined.. Non-serious events are listed at a 5% frequency threshold.

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jun 2015, a primary completion of May 2016 and a completion of May 2016. It does not say whether these dates are actual or estimated.

Results were first posted in Dec 2016, 7 months after primary completion.

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 9, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
