Trial summary

This study compares two intraocular lenses, the Softec HD and the Tecnis Z9002, used to replace the natural crystalline lens after cataract extraction. The variables compared include 1) the accuracy of targeted versus achieved refractive outcomes and 2) visual acuity outcomes three months after implantation. Read more about this study

About this study

Official title: A Randomized Fellow-eye Controlled Clinical Trial to Compare the Visual and Refractive Outcomes Between Two Aspheric IOLs With Different Dioptric Increments and Manufacturing Tolerances in Patients Undergoing Bilateral Cataract Surgery

This study compares two intraocular lenses, the Softec HD and the Tecnis Z9002, used to replace the natural crystalline lens after cataract extraction. The variables compared include 1) the accuracy of targeted versus achieved refractive outcomes and 2) visual acuity outcomes three months after implantation.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intraocular Lens (IOL) in people with Cataract, run by Lenstec Incorporated at 1 site in United States.

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 10 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: stopped early, as of the sponsor's last update on 18 Oct 2018. 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 United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Sponsor stopped study to re-design trial). 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?

Target versus Achieved Refraction (time frame: 3 Months Postoperative). 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 18 Oct 2018.
