Clinical Outcomes of MICROPURE and PodEye Monofocal Intraocular Lenses (PHY1803)

Comparison of Clinical Outcomes After Implantation of MICROPURE (PhysIOL) and PodEye (PhysIOL) Monofocal Intraocular Lenses Into the Two Eyes of the Same Patient

Prospective, non-randomised, open, controlled, single-center post-market clinical follow study about Micropure 1.2.3. and PODEYE intraocular lenses.

This clinical investigation is a prospective, non-randomised, open, controlled, single-center post-market clinical follow whereby study patients undergoing routine cataract surgery will have implantation of monofocal intraocular lens Micropure 1.2.3. (PhysIOL, Liège, Belgium) in one eye and implantation of monofocal intraocular lens PODEYE (PhysIOL, Liège, Belgium) in the contralateral eye of the same patient. The study purpose is to obtain clinical data on visual acuity and contrast sensitivity on patients implanted with Micropure 1.2.3. and PODEYE The devices under investigation (Micropure 1.2.3. and PODEYE) are a monofocal glistening-free hydrophobic acrylic intraocular lenses (IOLs) manufactured by the sponsor of this study PhysIOL sa/nv. The optical properties of the lenses are very comparable. The main difference is the mechanical design of the haptics, that is not expected to have an influence on the clinical outcomes. The IOLs will be implanted as part of the routine cataract surgery on patients suffering from cataract development. In total 76 patients will be recruited for this clinical study and receive the implantation of Micropure 1.2.3. and POPDEYE intraocular lenses. Subjects participating in the trial will attend study visits over a period of 12 months.

The slitlamp examination is one examination to analyse the integrity of eye structures and the implanted IOL. The examination is performed and documented according to the guidelines in ISO 11979-7:2018. With the slitlamp the ophthalmologist can observe the eyes stereoscopically. A focussed slit of light, which can be width-adjusted, is projected on the eye to be examined. The investigator observes this projection on the eye through a reflected light microscope. The slitlamp is used to observe the anterior and posterior part of the eye, including cornea, lens and anterior chamber. By dilating the pupil the fundus can also be examined. Following conditions shall be examined with the slitlamp: • Corneal status.

A questionnaire will be handed out to the surgeon right after the surgery to document the ease of use and possible issues during IOL implantation. These data will be used to compare the outcomes to different surgery techniques or injectors. The questionnaire is not validated and the outcomes serve only for the sponsor to receive feedback if one or the other IOL is easier to implant.
