  • Any subject who is going to be co-managed by an ophthalmologist or optometrist who is not approved as a Technolas Perfect Vision GmbH Excimer laser Investigator.
  • Subjects with anterior segment pathology, including dry eye syndrome and cataracts which in the Investigator's opinion, would interfere with best spectacle-corrected VA (BSCVA) or a successful treatment.

About this study

Official title: A Prospective Study to Evaluate the Safety and Effectiveness of the Presbyopic LASIK Algorithm

By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment.

This study will help us to answer 2 questions:

  1. How accurately this combined technique corrects distance and near vision
  2. Whether the correction is adequate to remove the complete need for supplementary near spectacles
Read the detailed description

LASIK is a surgical technique where the cornea is reshaped using a laser to provide visual correction. Typically, this procedure will only correct your long distance vision requiring the use of supplementary spectacles for reading and near vision.

The Technolas 217z Excimer Laser used to deliver the treatment is approved for use in the European Community for both treatment versions to correct separately the near vision and the distance vision for cases which need one or the other correction.

By using a new software two consecutive treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment.

This study will help us to answer 2 questions:

  1. How accurately this combined technique corrects distance and near vision
  2. Whether the correction is adequate to remove the complete need for supplementary near spectacles

What participants receive

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

  • SupracorProcedure or surgery

    Also called Myopia, Hyperopia, Presbyopia, PresbyLASIK

    All patients will undergo LASIK treatment on their non-dominant eye with a new laser software algorithm designed to treat both the distance and near vision components.

    The developed software algorithm uses the subjective refraction of the eye to create a treatment for the distance vision correction. This part of the treatment does not show any difference to a regular LASIK treatment for ametropic cases.

    In addition to the treatment for the distance vision a central ablation component will be added to address the near vision.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Supracor in people with Myopia and Hyperopia, run by Technolas Perfect Vision GmbH at 1 site in Mexico.

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 11 inclusion and 19 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 20 May 2015. 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 Mexico. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 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?

The percentage of treated patients with an uncorrected monocular high contrast Near VA of 20/40 or better (time frame: 6 Months). 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 NCT01322919, which also lists 8 linked publications.

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 20 May 2015.
