Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Investigational device: HOYA Vivinex™ Gemetric™ Plus Toric preloaded IOL, Model XY1-GPT2, XY1-GPT3, XY1-GPT4, XY1-GPT5, XY1-GPT6.

The investigational devices will be used in the proposed clinical investigation according to the instructions for use. The IOL is indicated for the visual correction of aphakia and pre-existing corneal astigmatism after implantation in the capsular bag in adult patients.
The IOL is indicated for use in adult cataract patient only.

The implantation of the IOL will be at the same time as the cataract surgery. Subjects will be implanted monocularly with the investigational or comparator lens in the study eye. The eligible eye will be the study eye. Should both eyes be eligible, the study eye will be the right eye (OD). However, any planned cataract surgery required for fellow eye will need to be done at least 2 weeks after and preferably within 3 months of the study eye surgery. No study specific procedure on fellow eye except for recording IOL information (name, manufacturer, mono-/bi-/multi-focal/others) and surgery timing for the fellow eyes in eCRF, if applicable.

Ophthalmic surgeons who have completed a residency in ophthalmology or its documented equivalent and are licensed to practice medicine and perform surgery at an investigative site will administer the IOL. Investigators for this clinical trial will be selected from surgeons who are experienced in small-incision phacoemulsification and IOL implantation in cataract patients and having experience with HOYA or similar preloaded IOLs.

Power range of the lens models:
Spherical power: +10.00D to +30.00D (in 0.50 D increments)
Addition Power: +3.50D (near), +1.75D (intermediate)
Cylinder Power (IOL Plane): XY1-GPT2: 1.00D, XY1-GPT3 to XY1-GPT6: 1.50D to 3.75D (0.75D step)

The investigational device will be implanted into the capsular bag of eye and remain there. Participants will be followed-up for 12 months to demonstrate clinical performance, effectiveness and safety.

Treatment: Devices
Comparator / control treatment
ALCON AcrySof® IQ PanOptix® Toric Trifocal IOL (i.e., PanOptix Toric), model TFNT20, TFNT30, TFNT40, TFNT50, TFNT60

The implantation of the IOL will be at the same time as the cataract surgery. Subjects will be implanted monocularly with the investigational or comparator lens in the study eye. The eligible eye will be the study eye. Should both eyes be eligible, the study eye will be the right eye (OD). However, any planned cataract surgery required for fellow eye will need to be done at least 2 weeks after and preferably within 3 months of the study eye surgery. No study specific procedure on fellow eye except for recording IOL information (name, manufacturer, mono-/bi-/multi-focal/others) and surgery timing for the fellow eyes in eCRF, if applicable.

Power range of the lens models:
Spherical power: 6.0 D ~ 30.0 D in 0.5 D increments; 31.0 D ~ 34.0 D in 1.0 D increments
Addition Power: 2.17 D intermediate and a +3.25 D near add power at the IOL plane (representing approximately +1.65 D and +2.35 D at the corneal plane after implantation, respectively, for an average human eye)
Cylinder Power (IOL Plane): TFNT20: 1.00 D, TFNT30: 1.50 D, TFNT40: 2.25 D, TFNT50: 3.00 D, TFNT60: 3.75 D

The comparator device will be implanted into the capsular bag of eye and remain there. Participants will be followed-up for 12 months.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Random codes will be generated by SAS 9.4. Interactive Response Technology (IRT). Randomisation is by central randomisation by computer. A subject will be randomised and assigned to a specific clinical investigation arm after confirmation of eligibility.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random codes will be generated by SAS 9.4. Interactive Response Technology (IRT). Randomisation will be stratified by the investigational site.
