About this study

Official title: Intra-surgical Evaluation of CATS Tonometer Prism and AMO Versus Alcon Phacoemulsification Machines

This study will measure the dynamic real-time intraocular pressure (IOP) in the anterior chamber during standard phacoemulsification surgery.

What is known:

  • Fluidics control is determined to be one of the primary drivers of physician decision making in choosing phacoemulsification equipment.
  • Active pressure system fluidic control has a perceived and possibly real (based upon recent literature) improvement in intra-cameral IOP stability and reduced pressure fluctuations.
  • Improved fluidics can allow for reduced dynamic IOP fluctuations, in-the-bag positioned phaco tip, and intra-cameral fluid flow all of which will likely improve corneal health post-operatively.
Being tested
Alcon phacoemulsification equipment, AMO phacoemulsification equipment

What participants receive

Questions about this trial

What is this clinical trial studying?

A study testing Alcon phacoemulsification equipment and AMO phacoemulsification equipment in people with Cataract Surgery, run by Intuor Technologies, Inc. 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 8 inclusion and 23 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 11 Oct 2018. 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?

Yes. Results are posted in the registry (first posted 28 Jul 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Eyes With Stable IOP (time frame: intraoperative). 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 11 Oct 2018.
