About this study

Official title: Visual Outcomes of Different Types of Functional Intraocular Lenses in Cataract Patients

This is a prospective, multi-center, randomized comparative study. The purpose of the study is to evaluate and compare the objective and subjective visual outcomes of different types of functional intraocular lenses (IOLs) in patients.

Read the detailed description

Analyzing the subjective and objective visual outcomes and related factors following the implantation of various types of intraocular lenses(bifocal, trifocal, extended depth of focus (EDOF), and astigmatism-correcting intraocular lenses), exploring the advantages, disadvantages, and suitable patient populations for different types of intraocular lenses, analyzing the factors affecting postoperative visual quality, and providing guidance to better assist patients with diverse needs in clinical settings, aiming to offer multidimensional postoperative visual quality."

What is being measured

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

  1. uncorrected distance visual acuity (UDVA)

    uncorrected visual acuity at 5 m

    Measured: one year

  2. best corrected distance visual acuity (BCVA)

    corrected visual acuity at 5 m

    Measured: one year

  3. uncorrected near visual acuity (UNVA)

    uncorrected visual acuity at 40 cm

    Measured: one year

  4. uncorrected intermediate visual acuity (UIVA)

    uncorrected visual acuity at 60 cm

    Measured: one year

Secondary outcomes (8)
  1. HOAs

    high order aberrations such as coma

    Measured: three months

  2. Strehl Ratio

    The derivative of point spread function (PSF)

    Measured: three months

  3. objective visual quality

    The modulation transfer function (MTF) curve

    Measured: three months

  4. contrast sensitivity

    Contrast sensitivity were obtained from the Functional Vision Analyzer

    Measured: three months

  5. visual functions

    Visual functions were obtained from the OCULUS Binoptometer 4P

    Measured: three months

  6. IOL condition

    IOL condition were obtained from the wavefront mode of the OPD-Scan III aberrometer.

    Measured: three months

  7. subjective satisfaction

    Satisfaction Questionnaire

    Measured: three years

  8. photic phenomena

    Questionnaire of photic phenomena

    Measured: three years

Questions about this trial

What is this clinical trial studying?

An observational study of Cataract and Visual Quality, run by Eye & ENT Hospital of Fudan University.

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 3 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: opening soon, as of the sponsor's last update on 23 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

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 Jin Yang (+8613671632525, jin_er76@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

uncorrected distance visual acuity (UDVA) (time frame: one year). The study lists 4 primary outcomes in all. 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 Oct 2023.
