About this study

Official title: Multicentric Clinical Study to Determine Safety and Efficacy of a Hydrophobic Acrylic Trifocal Intraocular Lens (IOL)

The study will be a multicentric, prospective open-label ethics committee approved clinical study to investigate safety, visual outcomes, contrast sensitivity and rotational stability after bilateral implantation of Isatis TF IOL following cataract surgery.

Read the detailed description

This is a staged, multicentric, controlled, prospective, open-label clinical study whereby patients undergoing routine cataract surgery will have bilateral implantation of hydrophobic acrylic refractive trifocal intraocular lenses (Isatis TF) or the monofocal control device Isatis.

The investigational device, Control lens and all study products, including the devices used for the study examinations, will be used within the intended use specifications from the manufacturer. In addition, no invasive or other burdening examinations will occur for the patient.

The study will be carried out in up to five clinical centers in Spain.

The device under investigation is a hydrophobic acrylic trifocal intraocular lens (IOL) manufactured by the sponsor of this study. The trifocality of this investigational device is based on a purely refractive principle with the goal to provide additional near and intermediate visual acuity with low photic side effects. The IOLs will be implanted in the course of routine cataract surgery and will benefit to patients suffering from cataract development.

The control device (Isatis) is a hydrophobic acrylic monofocal intraocular lens to be implanted during cataract surgery. This control lens is CE approved and commercially available in Spain. Isatis monofocal lens is the parent lens of the device under investigation and both lenses share mechanical and material properties.

In total 180 patients will be recruited for this clinical study and undergo bilateral implantation of the Isatis TF intraocular lens or Isatis lens in a 2:1 ratio. Subjects participating in the trial will attend a total of maximum 11 study visits over a period of 11-13 months. Subjects would have the option for unscheduled visits if required medically.

Data analyses will be performed after the last patient finished the 120-180 days postoperative examination.

What is being measured

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

  1. Primary Safety Endpoint: Rates of Adverse Events

    The objective is to compare the SPE (Safety and Performance Endpoints) rates of the investigational product to reference data stated in the according ISO standard for posterior intraocular lenses (EN ISO 11979-7:2018) based on minimum 100 subjects.

    Measured: 120-180 days postoperative

  2. Primary Performance Endpoint: Best Corrected Distance Visual Acuity

    The primary performance endpoint is to show non inferiority of Isatis TF compared to the monofocal comparator in terms of best corrected distance visual acuity (CDVA) by means of statistical significance.

    Measured: 120-180 days postoperative

Secondary outcomes (3)
  1. Secondary Safety Endpoint: Best Corrected Distance Visual Acuity compared to historical data

    The objective is to compare best corrected distance visual acuities (CDVA) above defined thresholds of the investigational product to the normative data stated in the according ISO norm (EN ISO 11979-7:2018) for posterior chamber intraocular lenses.

    Measured: 120-180 days postoperative

  2. Secondary Performance Endpoint: Distance Corrected Near Visual Acuity (DCNVA)

    Secondary performance endpoint is to show a statistically significant increase between pre-and postoperative findings on monocular Distance Corrected Near Visual Acuity (DCNVA) under photopic light conditions on the first implanted eye.

    Measured: 120-180 days postoperative

  3. Secondary Performance Endpoint: Distance Corrected Intermediate Visual Acuity (DCIVA)

    Secondary performance endpoint is to show a statistically significant increase between pre-and postoperative findings on monocular Distance Corrected Intermediate Visual Acuity (DCIVA) under photopic light conditions on the first implanted eye.

    Measured: 120-180 days postoperative

What does the primary outcome measure?

Primary Safety Endpoint: Rates of Adverse Events (time frame: 120-180 days postoperative). 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 NCT04465344, which also lists 3 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.
