About this study

Official title: Assessment of the Eye Surface and Subjective Symptoms After Using Dexamethasone Drops With and Without Preservatives in Patients After Cataract Surgery

The goal of this interventional, real world data study is to evaluate the impact of preservatives on the post-cataract ocular surface.

The main question is to learn about an effect of preservatives on the eye surface. The study aims to answer some important questions:

Read more
  • if the usage of preservatives has an impact on the eye surface healing process after cataract surgery
  • if patient comfort and quality of life improve more or more rapidly with preservatives-free eye drops.

Participants will be asked to undergo standard procedure of peri-cataract surgery care and in addition to survey about the ocular surface state.

Researchers will compare group that takes preservatives-free dexamethasone 0.1% with standard dexamethasone 0.01% solution to see if post-surgery eye surface healing properties differ from both groups.

What is being measured

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

  1. Best corrected visual acuity result

    best corrected visual acuity evaluated with standard ETDRS for distant and for near vision

    Measured: up to 21 days post-surgery

  2. Ocular staining score result

    standard staining score - a scale used with the fluorescein stain; higher value expres more severe outcome, normal values are around 0-1. Overal information can be found: https://entokey.com/a-simplified-quantitative-method-for-assessing-keratoconjunctivitis-sicca-from-the-sjogrens-syndrome-international-registry/

    Measured: up to 21 days post-surgery

  3. Ocular Surface Disease Index survey result

    a standard survey that patient will preform at each visit

    Measured: up to 21 days post-surgery

Secondary outcomes (5)
  1. Fluorescein Break-up Time assessment

    time to break-up the tear film after the instilation of the fluorescein eye drop (evaluated 3 fold and the mean will be taken into account)

    Measured: up to 21 days post-surgery

  2. SICCA scale assessment

    Scale that requires both fluorescein and lissamine green staining profile assesment - used in the standardised manner

    Measured: up to 21 days post-surgery

  3. Shirmer test 1 measurement

    test that evaluate the amount of tears (in mm on the test paper) that are produced within 5 minutes and are evaluated under the anesthesia

    Measured: up to 21 days post-surgery

  4. Intraocular pressure measurement

    Intraocular pressure measurement preformed by standard tonometer

    Measured: up to 21 days post-surgery

  5. Anterior chamber cell intensity measurement

    the standardised SUN assesment of the anterior chamber cell intensity will be preformed - a standardised scale

    Measured: up to 21 days post-surgery

Questions about this trial

What is this clinical trial studying?

A study testing preservative-free solution of standard post-cataract eye drops in people with Cataract and Surgical Injury, run by Spektrum Center of Clinical Ophthalmology at 1 site in Poland.

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 6 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 28 Sep 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 Poland. 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. Some participants in this study may receive a placebo. 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?

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?

Best corrected visual acuity result (time frame: up to 21 days post-surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05753787, which also lists 1 linked publication.

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 28 Sep 2023; AzTrials last refreshed its copy on 27 Oct 2026.
