Clinical Study to Investigate Rotational Stability, Visual Performance, Contrast Sensitivity, Patient Satisfaction and PCO Rate After Implantation of a Trifocal Toric IOL

Prospective, controlled, single-surgeon, single-center clinical study to compare visual acuity outcomes to data obtained in a similar study by the same principal investigator on the trifocal IOL POD F (study no. PHY1802, ClinicalTrials.gov ID: NCT03688425)

Study Overview

• Status: Active, not recruiting
• Conditions: Cataract; Presbyopia; Lens Opacities
• Intervention / Treatment: Device: IOL implantation experimental

Detailed Description

This is a prospective, controlled, single-surgeon, single-center clinical study, whereby patients undergoing routine cataract surgery will have mono- or bilateral implantation of trifocal toric intraocular lenses POD FT. The study is aimed to compare visual acuity outcomes the FineVision POD FT IOL to data obtained in a similar study by the same principal investigator on the trifocal FineVision POD F IOL (study no. PHY1802, ClinicalTrials.gov ID: NCT03688425), whereby patients undergoing routine cataract surgery will have bilateral implantation of trifocal intraocular lenses. The patients will either be implanted with the FineVision POD FT IOL in both eyes or, in case the corneal astigmatism in one of the two eyes of the same patient is too small to implant a toric lens, the FineVision POD F IOL will be implanted in this eye (both lenses: PhysIOL, Liège, Belgium).

The devices under investigation (FineVision POD FT and POD F) are trifocal glistening-free acrylic intraocular lenses (IOLs) manufactured by the sponsor of this study PhysIOL sa/nv. The main difference between the lenses is that that the POD FT IOL is the toric version of the POD F IOL. 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 11 study visits (1 preoperative, 2 operative and 8 postoperative) over a period of 24 months. Subjects would have the option for unscheduled visits if required medically.

Primary endpoint data will be collected at the 6 months follow up visit and secondary endpoint data will be collected at the 1 Day, 1 Week, 1 month, 6, 12 and 24 months postoperative visits. Data analyses will be done after the last patient finished the final examination to support the study publication plan

Photograph of IOL with dilated pupil to asses IOL rotation	This examination shall only be performed in eyes implanted with POD FT lenses. To determine the rotational stability of the toric lenses after implantation, the actual IOL orientation has to be recorded as the intended surgical position during surgery using a photograph through the surgery microscope or other technique in order to document the rotational position of the IOL. Additional orientations are measured and recorded at the follow up visits by taking retroilluminated photographs in mydriasis using the slit lamp. To determine the rotational stability it is important that the IOL axis marks of the toric IOL are visible as well concurrent structures of the eye (in the same image) that are fixed and stable. Preferred fixed structures are limbal vessels. The pupil is dilated if necessary to visualize the IOL axis marks.
