Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 104 eyes of 52 consecutive patients with bilateral cataracts operated between April and September 2021 were included. All patients were interested in spectacle independence. Each participant underwent bilateral sequential cataract surgery and bilateral implantation of a novel non-diffractive EDOF IOL (n=26) or a trifocal IOL (n=26). The patients selected the IOL model after they were fully informed regarding the advantages and disadvantages of each IOL, by their surgeon. Their degree of interest in greater spectacle freedom at far, intermediate, and near distances, as well as their daily activities such as frequency of night driving or reading habits were discussed. The possibility of photic disturbances was described and explained as well.

Who may be able to join

  • Cataract patients scheduled for surgery who are interested in spectacle independence.
  • Bilateral cataract with plan of bilateral sequential cataract surgery.
  • Adult patients older than 18 years of age
  • Normal cognitive function, able to understand advantages and disadvantages associated with different types of IOLs.

Who cannot join

  • Ocular diseases other than cataract including irregular astigmatism, diabetic retinopathy, age-related macular degeneration or any other retinal diseases, severe dry eye, glaucoma, amblyopia, uveitis, pseudoexfoliation syndrome, abnormal pupillary function, history of intraocular or corneal surgery, congenital eye abnormalities, or eye trauma.
  • Patients with high myopia with axial length (AL) ≥ 26,5 mm and high hyperopia (AL ≤ 21.5 mm)

About this study

Official title: Comparison of Visual Performance and Quality of Life With a Novel Non-diffractive Extended Depth-of-focus IOL and a Trifocal IOL

The purpose of this study is to compare visual performance and quality of life (QOL) following bilateral implantation of a novel non-diffractive extended depth-of-focus (EDOF) intraocular lens (IOL) (AcrySof® IQ Vivity, Alcon, TX, USA) and a trifocal IOL (Acrysof® IQ PanOptix, Alcon, Fort Worth, TX) in a prospective comparative interventional case series.

Read the detailed description

Developments in cataract surgical devices and intraocular lenses (IOL) increased patient expectations and changed the practice patterns in ophthalmology. Nowadays, cataract surgery is considered as a refractive surgery. With multifocal IOLs, spectacle independence can be achieved with a good distance, intermediate and near visual acuity. This is associated with increased quality of life after cataract surgery.The most important disadvantages of multifocal IOLs are loss of contrast sensitivity and photic phenomena such as glare and halo. Although multifocal IOLs are more frequently associated with photic disturbances than monofocal IOLs, the trifocal IOLs have improved performance in photic phenomena when compared to bifocal IOLs. Recently, a new technology known as extended depth of focus (EDOF) IOLs have been developed. These lenses create a single elongated focal point to enhance the depth of focus, improving intermediate vision without compromising distance vision. Although EDOF IOLs provide better intermediate distance vision when compared to monofocal IOLs, near vision is not as good as trifocal IOLs. The most important advantage provided by the EDOF technology is lower rate of photic disturbances than trifocal IOL designs. The aim of this study was to compare the visual performance and patient-reported quality of life (QOL) outcomes following bilateral implantation of a novel non-diffractive wavefront shaping EDOF IOL (AcrySof® IQ Vivity, Alcon Research, TX, USA) and a trifocal IOL (AcrySof® IQ PanOptix, Alcon Laboratories, Fort Worth, TX).

What participants receive

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

  • İntraocular lens implantationDevice

    Each participant underwent bilateral sequential cataract surgery and bilateral implantation of a novel non-diffractive EDOF IOL (n=26) or a trifocal IOL (n=26). The interval between the first and second-eye surgeries was 1 to 3 weeks. The patients selected the IOL model after they were fully informed regarding the advantages and disadvantages of each IOL, by their surgeon. Their degree of interest in greater spectacle freedom at far, intermediate, and near distances, as well as their daily activities such as frequency of night driving or reading habits were discussed. The possibility of photic disturbances was described and explained as well.

What is being measured

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

  1. Postoperative visual acuity with or without spectacle correction at near, far and intermediate distances

    uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), distance corrected intermediate visual acuity (DCIVA), distance corrected near visual acuity (DCNVA)

    Measured: postoperative third month

  2. Defocus-curves

    The monocular defocus curves were evaluated under photopic conditions using defocusing lenses from +0.50 D to -4.00 D in 0.50 D steps. The measurements were performed by adding the lenses to the CDVA.

    Measured: postoperative third month

  3. Contrast sensitivity

    Monocular and binocular contrast sensitivity was assessed with the Pelli-Robson chart under photopic conditions at 3 meters.

    Measured: postoperative third month

  4. Reading speed

    Reading speed was measured using the validated Turkish version of the MNREAD chart in photopic illumination conditions. It was recorded as number of words read by the patient in one minute (words per minute-wpm).

    Measured: postoperative third month

  5. Quality of vision / dysphotopsia

    Dysphotopsia was assessed by the Quality of Vision (QoV) questionnaire developed by McAlinden et al. The QoV is a validated Rasch-adjusted questionnaire in which patients are asked to rate specific dysphotopsia items depicted in standard photographs. Patients score each item (0, 1, 2, or 3) in relation to how frequent, severe, and bothersome their symptoms are (30 items in total). Lower QoV scores indicate a better quality of vision.

    Measured: postoperative third month

  6. Vision-related quality of life (QOL)

    The vision-related QOL was assessed three months after the surgery by the VF-14 QOL questionnaire that was administered face-to-face by a trained researcher (İK). The grading scale was as follows: 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. Special care was taken not to influence the patients and to ensure that each question was fully understood.

    Measured: postoperative third month

What does the primary outcome measure?

Postoperative visual acuity with or without spectacle correction at near, far and intermediate distances (time frame: postoperative third month). The study lists 6 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 NCT05262504, which also lists 1 linked publication.

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.
