Investigation for Assessing the Visual Performance of Hanita Lenses Intensity SL IOL in Comparison to Alcon Panoptix IOL

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:

1. To show non-inferiority in binocular distance corrected visual acuity for far, intermediate and near distances after Trifocal IOL implantation.
2. To show non-inferiority in the Defocus Curve measurement
3. To show non-inferiority in Contrast Sensitivity measurement
4. 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.

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.
