Description of intervention(s) / exposure
The purpose of this investigation is to compare the safety and effectiveness of the investigational AIOL to the approved commercially available trifocal IOL (Alcon PanOptix IQ) (active control) in patients undergoing bilateral cataract extraction and bilateral intraocular lens implantation.

Patients diagnosed with cataracts in both eyes, who require bilateral cataract extraction by phacoemulsification and are eligible for bilateral IOL implantation.

The study is a prospective, randomized, controlled, bilateral, multinational, subject and assessor-blinded design. The randomization employs a 1:1 ratio for subjects to receive either the investigational AIOL or a commercially available trifocal IOL (Alcon PanOptix IQ) (active control).

Subjects will be randomly assigned to receive bilateral implantation of the Acrysof® IQ PanOptix Trifocal IOL (Model TFNT00, Alcon, TX, USA) with an Alcon qualified delivery system or the investigational FluidVision MX AIOL (PowerVision, CA, USA) using the PowerJect Injector System following standard cataract extraction.

The trifocal lens (Alcon PanOptix IQ) restores vision at more than one distance, by splitting or stretching the light entering the eye. The investigational AIOL is designed to use the eye’s natural forces to change the shape and power of the lens, producing a change in lens power when needed.

Randomization will be stratified by site and both arms of the study will enrol the same number of subjects.

Eligible subjects must be able to undergo the second eye surgery using the same device as the first eye treatment.

The second surgery will occur after the 1 Week follow up on the first eye surgery is complete. Subjects will be followed at 1 day, 1 week, and 1, 3, 6, and 12 months post-surgery.

The intervention is intended to be a single visit outpatient surgery with follow-up visits, also at the the study’s affiliated clinic(s), at 1 day, 1 week, 1 month, 3, 6, and 12 months post-surgery, for each treated eye.

The study team member assigned to perform visual acuity assessments at each follow-up visit will be masked to the type of IOL that the subject receives.

The subject will also be masked to the type of IOL implant used during surgery. The implanting investigator performing the procedure will not be masked to the treatment assignment.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocated unmasked study staff member will perform the paper-randomization process, without masked study staff present. The Randomisation Envelopes (REs) with lowest number on top must be used in sequence: 1 through 30. The REs are sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The study is a prospective, randomized, controlled, bilateral, multinational, subject and assessor-blinded design. The randomization employs a 1:1 ratio for subjects to receive either the investigational AIOL or a commercially available trifocal IOL (Alcon PanOptix IQ) (active control).
Randomization will be sequence generated using a randomisation table created by computer software (ie computerised sequence generation and stratified by site). Both arms of the study will enrol the same number of subjects.

Enrollment
A maximum of 90 subjects will be enrolled. Forty-five (45) subjects will be assigned to each
cohort to allow for 40 evaluable subjects in each cohort.
Each study site is expected to enroll a minimum of 4 and a maximum of 22 subjects

Investigational Site Locations
Up to 15 clinical sites in up to 6 countries: Australia, New Zealand, South Africa, El Salvador, Canada, and the United Kingdom.

All subjects in whom an implant of either type is attempted (defined as insertion of cartridge tip into cornea with intent to implant a trifocal IOL (Alcon PanOptix IQ) or FluidVision MX AIOL) will be followed for the duration of the study, whether the assigned lens is successfully implanted or not.

Based on the subject biometry, the sponsor will assign each subject a lens that is best suited for the subject to provide optimal results for them.

Each interventional treatment provider will be required to complete an in-person hands on implant/explant training session and and will be provided an Instructions for Use document prior to implanting any device at their affiliated clinic/hospital. In addition, each procedure will be attended by a Sponsor-appointed proctor.

Statistical methods / analysis
Additional detail regarding data analysis is in the study’s Statistical Analysis Plan.
The proposed sample size (N = 40 evaluable per arm) will provide 80% power for the non-inferiority
hypothesis with respect to mean monocular DCNVA when tested at the 0.05 level of significance (one sided)with a non-inferiority margin of 0.10 logMAR assuming the difference in means is 0.0 logMAR (SD =0.18).

Data analysis will be completed for the following categories
A. Analyses Population
B. Subject Accountability
C. Demographics and Baseline characteristics
D. Interim Analyses
The primary analysis of primary and secondary effectiveness endpoints will be based on results from the 6 Month visit, except Rotational Stability which will be analyzed at the 3 Month visit. No interim analyses for the purposes of early stopping for benefit or modifications to the protocol are planned. Safety analysis of ISO-defined adverse events and rate of device deficiencies will be assessed at 6 Months and 12 Months.
Analyses of Primary Effectiveness Endpoint
1. Monocular Distance Corrected Near Visual Acuity at 40 cm at 100% contrast
Analyses of Secondary Effectiveness Endpoints
1. Monocular Distance Corrected Intermediate Visual Acuity at 66 cm at 100% contrast
2. Monocular Distance Corrected Intermediate Visual Acuity at 66 cm at 10% contrast
3. Monocular Distance Corrected Intermediate Visual Acuity at 66 cm at 25% contrast
4. Monocular Distance Corrected Near Visual Acuity 40 cm at 10% contrast
5. Monocular Distance Corrected Near Visual Acuity at 40 cm at 25% contrast
6. Range of vision between 4 m and 40 cm with the FluidVision lens (binocular, as measured by defocus curve testing)
Analysis of Safety Endpoints
1. Adverse Events and Device Deficiencies
2. Safety on the implantation procedure as defined by change in endothelial cell count
3. Evaluate contrast sensitivity
Descriptive summaries (counts and percentages) for ISO-defined and specific Anticipated Ocular AEs will be presented by IOL group.

Incidence rates observed for each IOL group will be compared to the ISO-defined cumulative (adverse events which occurred at any time during the investigation) and persistent (adverse events which are present at the 6 Month and 12 Month visit) adverse event SPE for posterior chamber IOLs using the 1-sided exact 95% lower confidence limit. In addition to SPE rates predefined in ISO 11979-7, the rate of adverse events that may be specifically related to test IOL design features; and any other significant events will be provided. These rates will be accompanied by 1-sided exact 95% lower/upper confidence limits.

The number and percentage of all adverse events will be tabulated with a breakdown by IOL group and implanted eye. A listing of all ocular adverse events will also be provided.

The number and percentage of all device deficiencies will be tabulated with a breakdown by IOL group and implanted eye. A listing of all device deficiencies will also be provided.
