This study is a multicentric, prospective, randomised, controlled, post-market clinical follow up (PMCF) study to investigate safety, visual outcomes and contrast sensitivity after bilateral implantation of either LuxSmart IOLs (study group) or LuxGood IOLs (control group).
This study is a multicentric, prospective, randomised, controlled, post-market clinical follow up (PMCF) study whereby subjects undergoing routine cataract surgery will have bilateral implantation of either LuxSmart IOLs (study group) or LuxGood IOLs (control group). The subjects will be randomized in a 1:1 ratio to receive the study or control lenses. Both study and control IOLs, are CE approved The study and control IOLs, and all devices used for the study examinations, will be used within the intended use specifications from the manufacturer. In addition, no invasive or other burdening examinations will occur for the subject. The study device (LuxSmart) is a hydrophobic, premium monofocal intraocular lens (IOL) manufactured by the sponsor of this study. The control lens (LuxGood) is the monofocal parent lens sharing the same material and optic design but with slight differences in the optic design. The IOLs will be implanted as part of the routine cataract surgery on subjects suffering from cataract. The targeted study cohort represents the standard subject cohort for cataract surgery. In total 238 subjects will be enrolled for this clinical study and receive bilateral implantation of the study or control lens based on a 1:1 randomization given by the EDC. Subjects participating in the trial will attend a total of 6 to 10 study visits (1 preoperative, 1 or 2 operative and 4 - 7 postoperative visits that may be carried out at the same day if requirements allow) over a period of 6 months. Data analyses will be performed after the last patient finished the 120-180 days postoperative examination.

Primary Safety Endpoint: Mean Corrected Distance Visual Acuity
The primary safety endpoint is to show that the mean monocular Corrected Distance Visual Acuity (CDVA) at at 120-180 days postoperative is statistically non-inferior to outcomes obtained in the control group using a non-inferiority margin of 0.1 logMAR, a 1-sided test and a significance level of 0.05. This analysis will be done for first implanted eyes as well as all implanted eyes per subject.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Monocular Contrast Sensitivity - Between-group mean difference
The co-primary safety endpoint is to compare the outcomes on monocular contrast sensitivity under mesopic light conditions (with and without glare) between the study and the control group at 120-180 days postoperative. This analysis will be done for first implanted eyes per subject. The following Log Contrast Sensitivity Analysis will be performed: \- Between-group mean difference in log contrast sensitivity with 90% non-parametric confidence interval for each spatial frequency.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Monocular Contrast Sensitivity - descriptive statistics
The co-primary safety endpoint is to compare the outcomes on monocular contrast sensitivity under mesopic light conditions (with and without glare) between the study and the control group at 120-180 days postoperative. This analysis will be done for first implanted eyes per subject. The following Log Contrast Sensitivity Analysis will be performed: \- Provide descriptive statistics for the log contrast sensitivity for each group (mean, SD, median, 0th, 25th, 50th 75th, and 100th percentiles) and for each spatial frequency.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Monocular Contrast Sensitivity - frequency with glare
The co-primary safety endpoint is to compare the outcomes on monocular contrast sensitivity under mesopic light conditions with glare between the study and the control group at 120-180 days postoperative. This analysis will be done for first implanted eyes per subject. The following Log Contrast Sensitivity Analysis will be performed: \- The percentage of eyes that can and cannot see the reference pattern for each spatial frequency.

Co-Primary Safety Endpoint: Monocular Contrast Sensitivity - frequency without glare
The co-primary safety endpoint is to compare the outcomes on monocular contrast sensitivity under mesopic light conditions without glare between the study and the control group at 120-180 days postoperative. This analysis will be done for first implanted eyes per subject. The following Log Contrast Sensitivity Analysis will be performed: \- The percentage of eyes that can and cannot see the reference pattern for each spatial frequency.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Best Corrected Distance Visual Acuity compared to historical data
The objective is to compare best corrected distance visual acuities (CDVA) above defined thresholds of the investigational product to the normative data stated in the according ISO norm (EN ISO 11979-7:2018) for posterior chamber intraocular lenses.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Rates of Adverse Events
The objective is to compare the SPE (Safety and Performance Endpoints) rates of the investigational product to reference data stated in the according ISO standard for posterior intraocular lenses (EN ISO 11979-7:2018) based on minimum 100 subjects.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Incidence of all SAE
The incidence of all Serious Adverse Events, including Secondary Surgical Interventions (SSIs) related to the optical properties of the IOL, in first-implanted eyes as well as all implanted eyes will be collected through Post-Operative Visit 4 (120 to 180 days after first and second eye implantation). The proportion of first implanted eyes and all implanted eyes with at least one serious adverse event will be summarized using categorical summary statistics by treatment received. Each eye will be counted only once in the calculation of the rate. There is no statistical hypothesis associated with the proportion of first implanted eyes with at least one serious adverse event.
Time frame: 120-180 days postoperative
Co-Primary Safety Endpoint: Rate of SSI Related to Optical Properties of the IOL
The rate of SSIs related to the optical properties of the IOL for first-implanted eyes as well as all implanted eyes will be reported through 120 to 180 days after first and second eye implantation. Secondary surgical interventions related to the optical properties of the IOL will be defined as IOL explantation, replacement, or repositioning due to subject intolerance of visual symptoms not adequately improved by spectacle correction. Each eye will be classified as either having undergone a secondary surgical intervention related to the optical properties of the IOL or not having undergone such an intervention. Secondary surgical interventions related to the optical properties of the IOL will be summarized categorically (Yes, No) by actual treatment received in a table.
Time frame: 120-180 days postoperative

Co-Primary Performance Endpoint: Monocular best-corrected distance defocus
Monocular best-corrected distance defocus testing will be performed. The defocus range where the mean visual acuity of 0.2 logMAR or better is achieved will be derived by visual inspection of the mean defocus curve. The monocular depth of focus is defined as the defocus range from zero to the first negative vergence level, where the visual acuity is 0.2 logMAR or less. One co-primary efficacy endpoint is to show that the monocular depth of focus for the eyes implanted with the study device is at least 0.5 D greater than the depth of focus for the eyes implanted with the control device at 0.2 logMAR.
