About this study

Official title: Vitreous Surgery With Intraocular Assistance (VISIA)

To Assess the Safety of Vitreous surgery with intraocular assistance (VISIA) \& to identify and document with video evidence and surgeon's case report forms intraocular maneuvers that are facilitated by VISIA.

Read the detailed description

Standard care surgery will be done with a few novel additions to facilitate the surgical procedure. Currently 3 ports are inserted by creating holes in the sclera (white part of the eye) to enter into the posterior part of the eye. When complex dissection is needed, a fourth port will be inserted. The assistant will insert light source through the 4th port. This eliminates the need for the surgeon to hold the light in one hand. Hence allows freeing of both hands for the surgeon to use a forceps in one hand to grasp and elevate membranes and a scissors in the other to cut connections between the retina and the membranes. When membranes are particularly thick, it can be difficult to dissect with a single forceps holding up the membrane. In this situation, a 5th port will be inserted allowing the assistant to insert a light source through one and a forceps though another. The surgeon will have a forceps in one hand and a scissors in another making dissection process more efficient.

Being tested
Intraocular assistance

What participants receive

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

  • Intraocular assistanceProcedure or surgery

    Intraocular assistance with help of surgical assistants during vitreous surgery (VISIA) in patients who require vitreous surgeries as part of standard of care procedure for conditions like retinal detachments, dislocated intraocular lens and glaucoma patients requiring endophotocoagulation.

What is being measured

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

  1. The primary outcome measure is recording of adverse events directly related to VISIA and adverse events unrelated to VISIA.

    Measured: 4 months

Secondary outcomes (2)
  1. Surgeon's assessment of the benefits and risks of VISIA recorded on the surgical case report form.

    Measured: 4 months

  2. Assistant's assessment of the benefits and risks of VISIA recorded on the surgical case report form.

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Intraocular assistance in people with Traction Retinal Detachments and Rhegmatogenous Retinal Detachments, run by Johns Hopkins University at 1 site in United States.

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 2 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: stopped early, as of the sponsor's last update on 26 Sep 2017. 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 United States. 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 was stopped early (reason given: Difficulty in finding patients with complex retinal pathology to enroll in this study.). Results are not available in the source record.

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?

The primary outcome measure is recording of adverse events directly related to VISIA and adverse events unrelated to VISIA. (time frame: 4 months). 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 26 Sep 2017.
