A Clinical Outcome Study of Two Multifocal Intraocular Lenses (IOL) in Cataract Patients

May 26, 2015 updated by: Alcon Research

Clinical Outcomes After Implantation of the AcrySof® IQ ReSTOR® +2.5 D Multifocal Intraocular Lens (MIOL) in the Dominant Eye and Randomization of the AcrySof® IQ ReSTOR® +2.5 D or +3.0 D MIOL in the Fellow Eye

The purpose of this study is to compare AcrySof® IQ ReSTOR® +2.5 D Multifocal IOL in both eyes (bilateral implantation) to AcrySof® IQ ReSTOR® +2.5 D Multifocal IOL in the dominant eye with AcrySof® IQ ReSTOR® +3.0 D Multifocal IOL in the fellow eye (contralateral implantation) at Month 3 following the second eye surgery.

Study Overview

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

Each subject will complete a preoperative examination of both eyes, implantation of IOL at the operative visit for each eye, and up to 4 postoperative visits (each eye examined at Day 1-2, with binocular visits at Day 30 and Day 90 after the second implantation). The second implantation will occur between 1 and 45 days of the first. If the first eye is not implanted during surgery, the second eye is not eligible. lf both eyes are not implanted with the assigned IOL, the subject will be followed for safety evaluation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

17 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Willing and able to understand and sign informed consent, and attend postoperative examinations per protocol schedule;
  • Requires cataract extraction followed by posterior intraocular lens implantation used as an on-label procedure in both eyes;
  • Willing to have second eye surgery within 45 days of first eye surgery;
  • Expected postoperative astigmatism < 1.0 D in both eyes, as measured by keratometry;
  • Free of severe diseases(s)/condition(s) listed in the Warnings and Precautions section of the package inserts;
  • Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

  • Refractive lens exchange (monocular DCVA of worse than 20/20, or ≥ 0.06 logMAR). This exclusion did not apply to binocular (OU) measurement;
  • Significant irregular corneal astigmatism as demonstrated by corneal topography;
  • Severe degenerative visual disorders;
  • Previous corneal surgery;
  • Amblyopia;
  • Planned multiple procedures, including LRI, LASIK, etc, during surgery or the course of the study;
  • History of corneal disease;
  • Severe diabetic retinopathy;
  • History of retinal detachment;
  • Severe conditions or acute or chronic diseases or illnesses that, per investigator's clinical judgment, would increase the operative risk or confound the results of the study;
  • Pregnant or planning pregnancy during course of study;
  • Other protocol-defined exclusion criteria may apply.

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
Binocular Distance Corrected Visual Acuity (logMAR) - Intermediate (60 cm)
Time Frame: Day 90 from second eye implantation
Visual acuity (VA) was tested binocularly (both eyes together) using the manifest refraction adjusted for optical infinity and the hand-held, 100% contrast, Early Treatment Diabetic Retinopathy Study (ETDRS) chart set at 60 centimeters (cm) on the nearpoint rod. VA was measured in logarithm minimum angle of resolution (logMAR) increments, with 0.1 logMAR corresponding to 5 letters, or 1 line, on the ETDRS chart. A lower logMAR value denotes better visual acuity.
Day 90 from second eye implantation

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.
Outcome Measure
Measure Description
Time Frame
Binocular Distance Corrected Visual Acuity (logMAR) - Near (40 cm)
Time Frame: Day 90 from second eye implantation
VA was tested binocularly using the manifest refraction adjusted for optical infinity and the hand-held, 100% contrast, ETDRS chart set at 40 cm on the nearpoint rod. VA was measured in logMAR increments, with 0.1 logMAR corresponding to 5 letters, or 1 line, on the ETDRS chart. A lower logMAR value denotes better visual acuity.
