简要总结
Prospective, non-randomised, open, controlled, single-center post-market clinical follow study about Micropure 1.2.3 IOL.
详细描述
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 bilateral implantation of monofocal intraocular lenses Micropure 1.2.3. (PhysIOL, Liège, Belgium)
The study purpose is to obtain clinical data on visual acuity and contrast sensitivity on patients implanted with Micropure 1.2.3.
The device under investigation (Micropure 1.2.3.) is a monofocal glistening-free hydrophobic acrylic intraocular lens (IOL) manufactured by the sponsor of this study PhysIOL sa/nv. The IOL will be implanted as part of the routine cataract surgery on patients suffering from cataract development.
In total 50 patients will be recruited for this clinical study and receive a bilateral implantation of Micropure 1.2.3. intraocular lens.
Subjects participating in the trial will attend a total of 8 study visits (1 preoperative, 2 operative and 5 postoperative) over a period of 2 Years.
