November 20, 2023 updated by: SightTrust Eye Institute

Evaluation of Quality of Vision and Spectacle Independence With Bilateral Implantation of the AcrySof® Panoptix® Intraocular Lens

This is a study to assess the spectacle independence and quality of vision of patients receiving the AcrySof® Panoptix® Intraocular lens (IOL) after uneventful cataract surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a single-arm unmasked clinical evaluation study of spectacle independence after successful bilateral cataract surgery. Subjects will be assessed pre-operatively, operatively and at 1 day, 1 month and 3 months post-operatively. Clinical evaluations will include administration of a spectacle independence questionnaire, as well as measurement of bilateral visual acuity and manifest refraction.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Subjects ≥40 years of age presenting for cataract surgery who are interested in reducing their dependence on spectacles at all distances, and who are appropriate candidates for multifocal lens implantation.

Description

Inclusion Criteria

Subjects are eligible for the study if they meet the following criteria:

Note: Ocular criteria must be met in both eyes.

  • Presenting for uncomplicated bilateral cataract surgery and have an interest in spectacle independence using a multifocal IOL or multifocal toric IOL option
  • Gender: Males and Females.
  • Age: 40 or older.
  • Willing and able to provide written informed consent for participation in the study.
  • Willing and able to comply with scheduled visits and other study procedures.
  • Have good ocular health, with no pathology that compromises visual acuity (outside of residual refractive error and cataract)
  • Have regular corneal astigmatism with a magnitude that can be treated with a non-toric IOL or a toric IOL in the approved ranged for the Panoptix lens.
  • Have 20/32 (0.2 logMAR) or better potential acuity in both eyes

Exclusion Criteria If any of the following exclusion criteria are applicable to the subject or either eye, the subject should not be enrolled in the study.

  • Irregular astigmatism (e.g. keratoconus)
  • Corneal pathology (e.g. scar, dystrophy, pterygium, severe dry eye)
  • Monocular status (e.g. amblyopia)
  • Previous radial keratotomy, corneal refractive surgery or other corneal surgery (e.g. corneal transplant, lamellar keratoplasty)
  • Previous anterior or posterior chamber surgery (e.g., vitrectomy, laser iridotomy)
  • Diabetic retinopathy
  • Macular pathology (e.g. age-related macular degeneration, epiretinal membrane)
  • History of retinal detachment
  • Subjects who have an acute or chronic disease or illness that would confound the results of this investigation (e.g., immunocompromised, connective tissue disease, clinically significant atopic disease, diabetes, and any other such disease or illness), that are known to affect postoperative visual acuity.
  • Participation in any investigational drug or device trial within the previous 30 days prior to the start date of this trial (or currently participating).

The principal investigator reserves the right to declare a patient ineligible or non-evaluable based on medical evidence that indicates they are unsuitable for the trial.

Pregnancy has a known effect on the stability of refractions and visual acuity. As such, subjects who become pregnant during the study will not be discontinued but their data may be excluded from analyses of effectiveness.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Emmetropic Subjects Who Are Spectacle Independent
Time Frame: 3 months
Number of patients who have a 3-month postoperative manifest spherical equivalent refraction within 0.5 diopters (D) of plano, and ≤ 0.5 D of refractive cylinder (emmetropic subgroup) who never or rarely wear spectacles for distance, intermediate or near vision 3 months postop (based on the Patient-Reported Spectacle Independence Questionnaire (PRSIQ) - "a little of the time" or "none of the time").
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
