Rotation of Hydrophobic Acrylic Lenses - Rayner RA0800C & Alcon Clareon & Hoya Nanex & Hoya Vivinex XY1-EM & RayOne EMV Toric & PODEYE Toric

Medical University of Vienna750 enrolled

Overview

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

Outcomes

Primary Outcomes

Change of axial intraocular lens position

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 or PODEYE 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°)

Time frame: 7 months

Secondary Outcomes

Decentration

Decentration 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. Decentration will be described as "Decentration in milimeter"

Time frame: 7 months

Tilt

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"

Time frame: 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

Time frame: 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)

Time frame: 7 months

UCIVA in the Alcon Clareon toric and Rayner RayOne EMV toric groups
