Yellow Versus White Study

Phase 4

Completed

• Conditions: Cataract
• Interventions: Procedure: cataract surgery (Hoya AF-1 [UY] YA-60BB); Procedure: cataract surgery (Hoya AF-1 [UV] VA-60BB lens)

• Registration Number: NCT00612781
• Lead Sponsor: Hospital Hietzing

Brief Summary

Blue-light-filtering IOLs are implanted increasingly often in cataract surgery. Several studies examined the effect of blue-light-filters on contrast and colour vision. However, the study outcomes were varying. The present study investigated the effect of a blue-light-filtering IOL on colour perception and contrast acuity using highly sensitive measurement methods.
