Posterior Capsule Opafication of Two Different Hydrophobic Acrylic Intraocular Lenses

Not Applicable

Completed

• Conditions: Age Related Cataracts
• Interventions: Device: Hoya Vivinex; Device: Alcon SN60WF

• Registration Number: NCT04196673
• Lead Sponsor: Medical University of Vienna

Brief Summary

On the day of surgery, the first eye to be operated is randomised to receive a Vivinex , HOYA Surgical Optics GmbH or an SN60WF, Alcon, Fort Worth, Texas. The second eye to be operated receives the other IOL type.

A complete biomicroscopic examination, visual acuity testing using autorefractometer, contrast sensitivity testing, and standardised retroillumination photography for PCO evaluation, will be performed 6 month (30-60 days), 1.5 years (± 3 months) and 3 (± 3 months) years postoperatively.
