Study Details

Study Description

Brief Summary

The goal of this clinical trial is to compare the visual performance between Intensity SL IOL and Panoptix IOL in men and women diagnosed with cataract who require cataract surgery procedure that meet the inclusion criteria and provide written informed consent will be enrolled in the study.

The main questions it aims to answer are:

To show non-inferiority in binocular distance corrected visual acuity for far, intermediate and near distances after Trifocal IOL implantation.
To show non-inferiority in the Defocus Curve measurement
To show non-inferiority in Contrast Sensitivity measurement
To show non-inferiority in patient satisfaction

Participants will attend a total of 10 study visits: 1 preoperative visit, 2 operations and 7 postoperative visits.

Detailed Description

This study is a single center, prospective, (1:1) randomized, unblinded, controlled study carried out in Germany according to Art. 74 MDR (PMCF study) or according to Art. 82 MDR / § 47 Para. 3 MPDG is carried out.

The lead investigator at the Heidelberg University Eye Clinic is Prof. Dr. Gerd U. Auffarth.

This study examines the visual performance of the trifocal Hanita Lenses Intensity SL IOL (study lens) compared to the trifocal Alcon PanOptix IOL (comparison lens) in bilaterally implanted patients. Clinical investigations including patient-reported results from the test group will be compared with those from the control group.

A total of approximately 58 patients will be included at 1 clinical center. Subjects participating in the study will attend a maximum of 10 study visits (1 preoperative, 2 operative and up to 7 postoperative) over a period of 3-7 months.

Only patients who have age-related cataracts will be included in the study. To participate in this study, patients must be at least 18 years old at the time of screening and a maximum preoperative corneal astigmatism of 1.0 D is permitted. All patients who would like to take part in this study will receive an information interview and further detailed study information in written form. Before a patient is admitted, he or she must sign a consent form.

The primary study endpoint is to investigate whether the binocular distance-corrected visual acuity achieved with the study lens for the distance, intermediate and near ranges is not statistically significantly inferior to the parameters achieved with the control lens.

The entire study including data processing will be carried out in accordance with EN ISO 14155:2020 Clinical Investigation of Medical Devices for Human Subjects, EN ISO 11979-7:2018: Clinical investigations of intraocular lenses for the correction of aphakia, EU MDR 2017/745, MEDDEV 2.7.1 rev. 4 Clinical Evaluation: A Guide for Manufacturers and Notified Bodies, MPDG:2020: Medical Device Law Implementation Act, as well as applicable local regulations and the Declaration of Helsinki.

Outcome Measures

Primary Outcome Measures

Binocular distance corrected visual acuity [3 months (90-120 days) post second eye operation]
To show non-inferiority in binocular distance corrected visual acuity for far, intermediate and near distances after Trifocal IOL implantation. Visual acuity will be performed by using ETDRS charts. All results will be expressed in logMAR. Visual acuity will be measured in photopic conditions.

Secondary Outcome Measures

Defocus Curve [3 months (90-120 days) post second eye operation]
To show non-inferiority in the Defocus Curve measurement by using ETDRS charts. The test will be performed using a phoropter to create defocus in 0.5D increments, starting from 1D to -4D relative to emmetropia so that the patient will be corrected for far vision.
Contrast Sensitivity [3 months (90-120 days) post second eye operation]
To show non-inferiority in Contrast Sensitivity measurement by using VectorVision at mesopic and photopic conditions. Luminance for photopic conditions will be 85cd/m² and 5cd/m² for mesopic conditions. Small deviations are allowed. The working interval for photopic conditions is 75-95cd/m² and for mesopic conditions is 5-15cd/m².
Patient satisfaction [3 months (90-120 days) post second eye operation]
To show non-inferiority in patient satisfaction by using the modified VF-14 questionnaire for quality of life, in addition to satisfaction questionnaire.
