Clinical Trial Summary

Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). Implantation of the IOLs is bilaterally.

Description:

This is a prospective, randomised, controlled, single-surgeon, single-center clinical study whereby patients undergoing routine cataract surgery will have bilateral implantation of trifocal intraocular lenses. The patients will either be implanted with the hydrophobic IOL FineVision POD L GF or the hydrophobic IOL FineVision POD F GF (both lenses: (PhysIOL, Liège, Belgium).

The devices under investigation (FineVision POD L GF and POD F GF) are trifocal glistening-free acrylic intraocular lenses (IOLs) manufactured by the sponsor of this study PhysIOL sa/nv. Both consist of the same hydrophobic material. The main difference between the lenses is the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). The IOLs will be implanted as part of the routine cataract surgery on patients suffering from cataract development.

Subjects participating in the trial will attend a total of 10 study visits (1 preoperative, 2 operative and 7 postoperative) over a period of 6 months. Subjects would have the option for unscheduled visits if required medically.

Primary and secondary endpoint data will be collected at the 6 months follow up visit. Data analyses will be done after the last patient finished the final examination to support the study publication plan.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Monocular Best Corrected Distance Visual Acuity (CDVA) under photopic light conditions.	No statistically significant difference between the two study groups on monocular CDVA at 3 months follow up visit. A significance level of 0.05 or lower (p < 0.05) will be considered statistically significant. CDVA is measured with ETDRS charts placed in 4m distance with best aided corrective glasses according to ISO 11979-7:2014.	3 months postoperative
Secondary	Manifested refraction	The manifested refraction is measured by means of a phoropter. The data contains values for sphere, cylinder and axis of cylinder according to ISO 11979-7:2014.
