About this study

Official title: Assessment of a Hand-held Femtosecond Laser to Perform Anterior Capsulorhexis During Cataract Surgery

This study is a Pre-market first-in-man clinical investigation to validate performance of a hand-held femtosecond laser named CATSYS.

Read the detailed description

Interventional, prospective, longitudinal (follow-up: 30 ± 10 days), single-arm, single center, open trial. The "first-in-man" character of this investigation relies on the ergonomics of CATSYS (handpiece), and not on the laser technique, which is similar to other FLACS.

The purpose of the clinical investigation is to document the compliance of the investigational medical device with the general requirements of performance, safety and clinical benefit, in order to complete existing data and obtaining CE-mark for CATSYS.

Being tested
cataract surgery with CATSYS

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • cataract surgery with CATSYSDevice

    patient diagnosed with cataract requiring surgery will have an anterior capsulorhexis with CATSYS

Study groups in NCT05141370
Study groupRoleWhat they receive
hand-held femtosecond laserExperimentalAnterior capsulorhexis will be performed with a hand-held femtosecond laser named CATSYS.
Receives: Device: cataract surgery with CATSYS

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Continuity of the capsulorhexis (success / failure)

    Success achieved if:

    • the anterior capsule is completely cut (rhexis is free floating or easy to remove)
    • AND there are no peripheric tears that can generate the rupture of the capsule at the end of rhexis removal.

    Measured: During surgery

Secondary outcomes (3)
  1. Adverse device effects

    Collection of adverse device effects by the investigator on the retina, on the cornea, on the posterior capsula and other adverse device events

    Measured: 3 to 5 days after surgery

  2. Adverse events

    Collection by the investigator of other adverse events

    Measured: 3 to 5 days post-surgery;

  3. Ocular adverse events

    Collection by the investigator of ocular adverse events

    Measured: 30 ± 10 days post-surgery.

Questions about this trial

What is this clinical trial studying?

A study testing cataract surgery with CATSYS in people with Cataract Surgery, run by Ilasis Laser at 1 site in France.

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 3 inclusion and 17 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: finished, as of the sponsor's last update on 2 Oct 2023. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Continuity of the capsulorhexis (success / failure) (time frame: During 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 2 Oct 2023.
