About this study

Official title: Visual Outcome Evaluation and Genetic Analysis: Shanghai Pediatric Cataract Study

The purpose of this study is to evaluate the long-term visual outcome of the cataract surgery using a large-scale and comprehensive database of pediatric cataract participants, including congenital and traumatic cataract. The investigators will further investigate into the various genetic and environmental factors that may contribute to the pathogenesis of pediatric cataract.

Being tested

What participants receive

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

  • intraocular lens implantationProcedure or surgery

    1)Pediatric cataract patients with intraocular lens implantation and those without intraocular lens implantation;2)Traumatic cataract patients with intraocular lens implantation and those without intraocular lens implantation

Congenital cataract groupCataract patients diagnosed with congenital cataract.
Receives: Procedure: intraocular lens implantation
Traumatic cataract groupCataract patients diagnosed with traumatic cataract.
Receives: Procedure: intraocular lens implantation

What is being measured

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

  1. Differences in the visual outcomes of pediatric cataract patients.

    Visual outcomes are evaluated including visual acuity with or without correction, refractive changes, intraocular pressure, fundus function, fixation type, vision development, growth of axial length, contrast sensitivity and other visual outcome measurements.

    Measured: Follow-up until ten years after surgery.

  2. Genetic diversity based on biospecimen samples of pediatric cataract patients.

    Sequencing of genes (including exons, promoters, 5' UTR and 3' UTR sequences) on a large scale to intensively investigate into the sites and functions of single nucleotide polymorphism (SNP) correlated with clinical features of congenital cataract patients, compared to traumatic cataract patients.Samples of blood, aqueous humor, anterior capsular membranes and lens tissues were applied for the genetic analysis.

    Measured: Analyzed within six months after surgery.

Secondary outcomes (1)
  1. Differences in the clinical phenotypes of pediatric cataract patients.

    Cataract type and severity of ametropic cataract patients are evaluated and images are captured before receiving the cataract surgery.

    Measured: Evaluated before receiving the cataract surgery.

Questions about this trial

What is this clinical trial studying?

An observational study of Pediatric Cataract and Congenital Cataract, run by Evidence Based Cataract Study Group at 1 site in China.

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 2 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: looking for participants now, as of the sponsor's last update on 27 Sep 2024. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yi Lu, M.D. (+86-02164377134, luyieent@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Differences in the visual outcomes of pediatric cataract patients. (time frame: Follow-up until ten years after surgery.). 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 NCT03063216, 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 27 Sep 2024; AzTrials last refreshed its copy on 26 Oct 2026.
