About this study

Multiple intraocular lens are nowadays available for implantation after cataract surgery. They use different technology to try to improve patient spectacle independence. It is necessary to better characterise the performence of each type of lens, as well as to define how they are affected by residual refractive errors. The purpose of this study is to evaluate visual function in patients implanted with different lenses (advanced monofocals, trifocals) in order to be able to recommend the best type of lens for each patient.

Being tested
Cataract surgery with bilateral implantation of the same type of intraocular lens

Questions about this trial

What is this clinical trial studying?

An observational study of Lenses, Intraocular, run by Clínica Rementería at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intermediate binocular uncorrected visual acuity (time frame: 3-9 months after cataract surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2022.
