NCT05875922 | COMPLETED | Cataract

Comparison of ISOPURE and EYHANCE (Switzerland)
Sponsor:

Beaver-Visitec International, Inc.

Brief Summary:

This is a prospective randomised open-label study with the aim to compare the visual performance of the premium monofocal Isopure IOL versus the extended depth of focus Eyhance® IOL after phaco-emulsification cataract surgery.

Condition or disease

Cataract

Lens Opacities

Intervention/treatment

IOL implantation experimental (ISOPURE 1.2.3.)

IOL implantation active comparator (TECNIS Eyhance)

Phase

NA

Detailed Description:

This is a single center, prospective, randomised, controlled, double-blind post-market clinical follow-up (PMCF) study whereby patients undergoing routine cataract surgery will have bilateral implantation of premium monofocal intraocular lenses (PhysIOL ISOPURE 1.2.3.) or EDOF lenses (TECNIS Eyhance). The patients will be randomized in a 1:1 ratio to receive the study or control lenses. Both IOLs, investigational device and control device, are CE approved and commercially available in the countries this clinical investigation is being carried out. The investigational device 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 device under investigation (ISOPURE 1.2.3.) is a hydrophobic, glistening-free, acrylic premium monofocal intraocular lens (IOL) manufactured by the sponsor of this study, PhysIOL sa/nv. The control lens (TECNIS Eyhance) is a non-diffractive Extended Vision Posterior Chamber IOL. The IOLs will be implanted as part of the routine cataract surgery on patients suffering from cataract development. Subjects participating in the trial will attend a total of 6 study visits (1 preoperative, 1 operative and 4 postoperative) over a period of 6 months. Subjects would have the option for unscheduled visits if required medically. Primary and secondary endpoint data will be collected at the 120-180 days follow up visit.

Estimated Enrollment : 70 participants
Masking : DOUBLE
Masking Description : Double-blind masking; Patient will not be informed which IOL model was implanted until end of the study. Outcomes assessors will not be informed which IOL model was implanted until end of the study.
Primary Purpose : TREATMENT

Exclusion Criteria
  • * Age of patient \< 50 years;
  • * Regular total corneal astigmatism \>1.0 dioptres (measured by topography method)
  • * Irregular astigmatism;
  • * Difficulty for cooperation (distance from their home, general health conditions);
  • * Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal or optic disorders);
  • * Subjects who may be expected to require retinal laser treatment during the course of the study or at a greater risk of developing cystoid macular edema or macula pucker; previous laser treatment for peripheral retinal tears is allowed;
  • * Previous intraocular or corneal surgery or intravitreal injection;
  • * Traumatic cataract;
  • * History or presence of macular edema;
  • * Glaucoma with visual field defects; or RNFL defects on OCT; ocular hypertension is allowed;
  • * Pupil abnormalities (non-reactive, tonic pupils, abnormally shaped pupils or pupils that do not dilate under mesopic / scotopic conditions);
  • * Amblyopia with monocular preoperative CDVA of \>0.1 logMAR;
  • * Cornea guttata;
  • * Keratoconus;
  • * Chronic uveitis;
  • * Expected complicated surgery;
  • * Significant dry eye;
  • * Contra-indications as listed in the current Instructions for use (IFU);
  • * Contra-indication or unwillingness to perform immediate sequential bilateral cataract surgery;
  • * Concurrent or previous (within 60 days) participation in another drug or device investigation.
  • In addition to above mentioned in- and exclusion criteria, subjects shall be discontinued when certain conditions are present at the time of surgery, including
    • * zonular instability or defect;
    • * capsular fibrosis or other opacity; and
    • * inability to fixate IOL in desired position. In such cases, the subject shall be followed until the condition has stabilized.
