About this study

Official title: Comparison of Phacoemulsification Platform Stellaris With Standard Infusion and Stellaris Elite With Pressurised Bottle in Myopic Eyes Concerning Deepening of Anterior Chamber as Measured by Intra-operative OCT

Clinical performance of phacoemulsification platform Stellaris Elite with standard irrigation fluid bottles in myopic eyes. Anterior chamber depth and patients comfort will be compared between the two groups.

Read the detailed description

Today phacoemulsification is the most important and safest procedure to perform cataract surgery. However, there are factors that can increase the risk of complications, one of them is an intraoperative increase of intraocular pressure (IOP) which may cause choroidal haemorrhage, capsular block syndrome, or posterior capsular rupture .

Also, more regularly, alterations of IOP provoke sudden changes of the anterior chamber depth, especially in myopic eyes due to intra-operative inverse irido-capsular block, which may result in pain or discomfort for the patient. The deepening of the chamber also makes the surgical maneuvers more challenging in such eyes.

As prevention of such adverse events, it is important to maintain a more or less constant IOP intraoperatively. To ensure this, the pressure of the irrigation fluid must be adjusted to the outflow of aqueous humor, usually by adapting the height of the irrigation fluid bottle (passive fluidics system). As a variable vacuum is produced at the phaco tip to enable the suction of lens fragments, there often are fluctuations of IOP, therefore the surgeon is required to constantly adjust the height of the irrigation fluid bottle.

A novel method to relieve the surgeon of this often-distracting task is to use all-in-one phacoemulsification systems that are able to monitor vacuum flow rates and then adjust the pressure of the irrigation fluid intraoperatively, also resulting in less fluctuations of IOP (active fluidics system). This should also result in reduced deepening of the anterior chamber and less risk of the adverse events as explained above.

What participants receive

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

Myopic patientsExperimentalIn myopic patients with axial length over 25.0 mm during surgery of the first eye the Stellaris platform will be used and during surgery of the second eye the Stellaris Elite platform will be used
Receives: Device: Stellaris Elite

What is being measured

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

  1. Anterior chamber depth

    Anterior chamber depth will be measured using the IOL Master 700. Fluctuations in anterior chamber depth will be compared between the eyes where Stellaris and the contralateral eyes in which the Stellaris Elite platform was used

    Measured: 12 months

Secondary outcomes (1)
  1. Patients discomfort

    Patients will be asked concerning their discomfort during both cataract surgeries and results will be recorded using an visual analogue scale. In the visual analogue scale 10 means highest discomfort and 1 stands for lowest discomfort.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Stellaris Elite in people with Cataract, run by Prim. Prof. Dr. Oliver Findl, MBA at 1 site in Austria.

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 5 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: status not confirmed, as of the sponsor's last update on 23 Nov 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 Austria. 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?

Contact Kristina Stjepanek, MD (01 91021-57564, office@viros.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Anterior chamber depth (time frame: 12 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 23 Nov 2018.
