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, RayOne EMV toric and PODEYE Toric group, patients receive a toric IOL according to their preoperative astigmatism

Tilt of the intraocular lens Rayner RayOne or Hoya Nanex or Hoya Vivinex Impress or Alcon Clareon toric or Rayner RayOne EMV toric or PODEYE Toric will be measured with the Casia 2 OCT. Tilt will be described as "Tilt in degrees at a certain axis" |
| 7 months |
| Anterior chamber depth | The anterior chamber depth (Axial position of the IOL) of the intraocular lens Rayner RayOne or Hoya Nanex or Hoya Vivinex Impress or Alcon Clareon or Rayner RayOne EMV toric or PODEYE Toric will be measured with the Casia 2 OCT after 1 month. The anterior chamber depth will be measured in milimeter | 1 month |
| Best corrected visual acuity (BCVA) | 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 |
