What participants receive

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

  • Refractive Technique (MR #1)Device

    Fogging method that employs fogging lens to ensure there is sufficient visual defocus to induce blur.

  • Refractive Technique (MR #2)Device

    Duochrome method that employs the chromatic aberration of the eye, with the shorter wavelengths (green) focused in front of the longer (red) wavelengths

Study groupRoleWhat they receive
MR #1/MR #2Subjects who participated in PCOL-102-AHSF who were bilaterally implanted with TECNIS IOL lenses will be randomized into the (MR #1/MR #2) sequence and receive two different maximum refractive techniques one at a time consecutively.
Receives: Device: Refractive Technique (MR #1); Device: Refractive Technique (MR #2)
MR#2/MR#1Subjects who participated in PCOL-102-AHSF who were bilaterally implanted with TECNIS IOL lenses will be randomized into the (MR#2/MR#1) sequence and receive two different maximum refractive techniques one at a time consecutively.
Receives: Device: Refractive Technique (MR #1); Device: Refractive Technique (MR #2)

What is being measured

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

  1. Difference between two manifest refractive techniques on outcome variable MRSE

    Refractive technique 1 will use a plus lens fogging technique and refractive technique 2 will use the Duochrome technique to achieve maximum plus refraction for best-corrected visual acuity (BCDVA).

    Measured: Day 0

  2. Difference between two manifest refractive techniques on visual acuity

    Refractive technique 1 will use a plus lens fogging technique and refractive technique 2 will use the Duochrome technique to achieve maximum plus refraction for best-corrected visual acuity (BCDVA).

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

An observational study of Refractive Error, run by Johnson & Johnson Surgical Vision, Inc. at 1 site in Australia.

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 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: finished, as of the sponsor's last update on 6 Jan 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 Australia. 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?

Difference between two manifest refractive techniques on outcome variable MRSE (time frame: Day 0). 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?
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 Jan 2023.
