About this study

Official title: Randomized, Prospective, Descriptive and Comparative Clinical Study of Macular Grasping Damage in Patients Undergoing Pars Plana Vitrectomy and Peeling of the Internal Limiting Membrane, Operated by Traditional Microscope or NGENUITY® 3D Visualization System With Heads-up Display System. A Pilot Study.

Randomized, prospective, descriptive and comparative clinical study. The comparison is between a group of patients affected by macular pucker or macular hole, whose macular peeling is performed using a traditional optical microscope (Leica F40) - control arm, and a group of patients affected by macular pucker or macular hole whose macular peeling is performed by 3D heads-up microscopy system (NGenuity 3D, Alcon) - experimental arm.

It is a blind study for both the operator that collects data and for the statistician.

Being tested
Macular surgery with NGENUITY surgical display system, Macular surgery with standard operating microscope

What is being measured

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

  1. SANFL detection

    Post-surgical analysis of SANFL (Swelling of the Arcuate Nerve Fiber Layer) measured on infrared, blue auto-fluorescence images and OCT images of peripapillary region

    Measured: 2 weeks after surgery

Secondary outcomes (6)
  1. Intraoperative time

    Mean duration of the surgical procedure

    Measured: during surgery

  2. ILM staining

    Number of internal limiting membrane staining procedures necessary

    Measured: during surgery

  3. ILM grasping

    Number of ILM grasping attempts.

    Measured: during surgery

  4. Light

    Lumen of light used

    Measured: during surgery

  5. Surgeon ergonomics

    Number of episodes of both back and neck pain

    Measured: during surgery

  6. BCVA

    Best Corrected Visual Acuity

    Measured: baseline, 1 month and 3 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Macular surgery with NGENUITY surgical display system and Macular surgery with standard operating microscope in people with Comparison of 3D Visualization and Microscope for VR Surgery, run by Anna Rita Daniele, MD at 1 site in Italy.

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 4 inclusion and 4 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 22 Dec 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 Italy. 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?

SANFL detection (time frame: 2 weeks after 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 22 Dec 2022.
