Study Details

Study Description

Brief Summary

The study aims to evaluate the clinical outcomes six months after implantation of the trifocal diffractive intraocular lens Asqelio Trifocal IOL TFLIO130C in healthy subjects submitted to non-traumatic cataract surgery.

This clinical performance will be assessed in terms of refractive error, visual performance at different distances, incidence of adverse events and complications following implantation, and patient satisfaction.

    Outcome Measures

    Primary Outcome Measures

    1. Adverse events [Six months after implantation]

      Percentage of subjects with adverse events (Ocular and Not Ocular, Severe and Not Severe), including secondary surgical procedures

    2. Refraction [Six months after implantation]

      Manifest refraction both monocular and binocularly using subjective methods

    Secondary Outcome Measures

    1. Uncorrected visual acuity for distance (4m) [Six months after implantation]

      Monocular visual acuity for distance (4m), without any additional correction, using ETDRS vision chart

    2. Best-corrected visual acuity for distance (4m) [Six months after implantation]

      Monocular visual acuity for distance (4m), with the best correction for distance, using ETDRS vision chart

    3. Uncorrected visual acuity for intermediate [Six months after implantation]

      Monocular visual acuity for intermediate distance (60cm), without any additional correction, using ETDRS vision chart

    4. Best-corrected visual acuity for intermediate [Six months after implantation]

      Monocular visual acuity for intermediate distance (60cm), with the best correction for distance, using ETDRS vision chart

    5. Uncorrected visual acuity for near [Six months after implantation]

      Monocular visual acuity for near distance (40cm), without any additional correction, using ETDRS vision chart

    6. Best-corrected visual acuity for near [Six months after implantation]

      Monocular visual acuity for near distance (40cm), with the best correction for distance, using ETDRS vision chart

    7. Contrast sensitivity function (CSF) [Six months after implantation]

      CSF with best correction, with and without induced glare, using the Clinical Trial Suite

    8. Defocus curve [Six months after implantation]

      Defocus curve of visual performance varying the stimulus vergence from -4.0 D to +1.0 D in 0.5 D steps with the best correction for distance
