Rotation of Hydrophobic Acrylic Lenses - Rayner RA0800C & Alcon Clareon & Hoya Nanex & Hoya Vivinex XY1-EM & RayOne EMV Toric
The investigational devices are approved intraocular lenses (IOL) intended to be implanted after phacoemulsification in individuals suffering from age-related cataract with the need of cataract surgery. Within the study, three different IOLs will be investigated and separately evaluated. Cataract surgery with IOL implantation will be performed in subjects who have signed an informed consent form. Postoperative examinations will be postoperative refraction, visual acuity, slitlamp examination, and rotation of the IOL within 1 hour, 1 week, 1 month and 4-7 months.
In the Alcon Clareon toric and RayOne EMV toric groups, patients receive a toric IOL according to their preoperative astigmatism

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change of axial intraocular lens position
Time Frame: 7 months
|
Change in axis position of an intraocular lens Rayner RayOne or Hoya Nanex or Hoya Vivinex Impress or Alcon Clareon toric or Rayner RayOne EMV toric from end of surgery (baseline axis) to 1 hour, 1 week, 1 month and 4-7 months (end of study visit).
The change in axis position will be evaluated with respect to the baseline measurement at the end of surgery.
Differences in axis position will be described as rotation in degrees (0 to 360°)
|
7 months

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Best corrected visual acuity (BCVA)
Time Frame: 7 months
|
BCVA will be measured at 1 week, 1 month and 4 to 7 months.
The BCVA will be described as the minimum angle of resolution (logMar)
|
7 months
|
Decentration
Time Frame: 7 months
|
Decentration of the intraocular lens Rayner RayOne or Hoya Nanex or Hoya Vivinex Impress or Alcon Clareon toric or Rayner RayOne EMV toric will be measured with the Casia 2 OCT.
Decentration will be described as "Decentration in milimeter"
