About this study

Official title: Efficacy of the Intracamerally Administered Mydriatics for Cataract Surgery in Patients With Primary Open-angle Glaucoma.

The aim of this study is to compare Mydrane ®, mydriatic eye drops and Mydriasert ® in terms of pupil site stability, surgical time, visual field and anterior chamber configuration modifications among primary open angle glaucoma (POAG) patients during cataract extraction surgery.

Read the detailed description

60 patients with coexisting POAG and cataract who underwent elective cataract extraction. All patients underwent ophthalmic routine examinations including automatic visual field examination, anterior chamber configuration, specular microscopy and arterial blood pressure measurement prior to surgery, 24 hours and 30 days postoperatively. All cataract surgeries were videorecorded, and all measurements were performed using media player. 20 patients received topical mydriatic eye drops, 20 patients received Mydriasert ® whereas 20 patients received intracameral injection of Mydrane ® just after the first incision.

What is being measured

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

  1. Stability of mydriasis

    All cataract surgeries were video-recorded, and all measurements were performed using media player software (VideoLAN Non-Profit Organization, Paris, France) with two different operators (M.R. and F.R.) based on the images acquired immediately prior to the corneal incision (T1), injection of the ophthalmic viscosurgical device (OVD) (T2), capsulorhexis (T3), IOL insertion (T4), and cefuroxime injection (end of surgery) (T5). The pupil size immediately prior to the capsulorhexis was defined as the maximum mydriasis. We recorded all the surgery with OPMI LUMERA® 700 ZEISS and then measured with media player software all the pupil size.

    Measured: 1 hour

  2. Duration of surgery

    mean duration of surgery, All cataract surgeries were video-recorded, and all measurements were performed using media player software (VideoLAN Non-Profit Organization, Paris, France) with two different operators (M.R. and F.R.) based on the images acquired immediately prior to the corneal incision (T1), injection of the ophthalmic viscosurgical device (OVD) (T2), capsulorhexis (T3), IOL insertion (T4), and cefuroxime injection (end of surgery) (T5).

    Measured: 1 hour

Secondary outcomes (4)

  1. Pain experience

    Patients were asked to complete a questionnaire using the the Visual Analogue Scale (VAS) scale to evaluate surgical pain related to the procedure. The scale simply consists of a 10 cm strip of paper which has two "end points" at the ends which are defined as "no pain" and "the worst pain I can imagine".

    Measured: up to 4 weeks

  2. Central corneal thickness (CCT) and corneal endothelium cell density (CD) changes

    Specular microscopy values were evaluated by using the Perseus (CSO, Italy) The Perseus specular microscope is a non-contact automated instrument with auto alignment and a touch screen that automatically conducts studies for measuring endothelial cell layer density using the corner method to analyze the endothelial cells. The instrument has a reliability index that evaluates the quality of acquisition, this is based on a calculation of the percentage of the total endothelium area relative to the maximum number of countable endothelial cells per field (edited area). Corneal endothelial cell density (CD) is calculable using a units of measure based on cells/mm2.

    Measured: up to 4 weeks

  3. Visual field defects

    The 30-2 SITA STANDARD algorithm (HFAII740: Humphrey Field Analyzer II; Carl Zeiss Meditec, Dublin, California, USA) was used for the standard automatic visual field examination of all the patients to investigate the visual field defects, mean deviation (MD), and pattern standard deviation (PSD) modifications at baseline and 30 days postoperatively. Visual field testing was performed with visual correction in a dark room.

    Measured: up to 4 weeks

  4. Anterior segment parameters variations

    Anterior chamber depth (ACD) and both nasal and temporal iridocorneal angles were measured by a single experienced operator who obtained a horizontal scan, including sections of the nasal and temporal quadrants of all the patients, using AS-OCT (Visante, software version 2.01.88; Carl Zeiss Meditec, Dublin, CA) in a dark room with the images centered on the pupil . High-resolution images were taken in the anterior segment single-scan mode along the horizontal meridian with the subjects seated.When the corneal reflex was visible, the image was captured. ACD (from the corneal endothelium to the anterior surface of the crystalline lens) were then measured (ACD was obtained using the on-screen calibrated caliper function).

    Measured: up to 4 weeks

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 6 Jul 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 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?

Stability of mydriasis (time frame: 1 hour). The study lists 2 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 NCT05925894, 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 6 Jul 2023.
