Yellow Versus White Study

Influence of Blue-Light-Filter IOLs on Color Perception and Contrast Acuity. A Randomized, Double-Masked Study With Intraindividual Comparison.

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.

Inclusion Criteria:

• bilateral age-related cataract
• age 55 to 80 years
• expected postoperative visual acuity of at least 1.0

Exclusion Criteria:

• amblyopia
• corneal scars
• diabetes
• arterial hypertonia
• pseudoexfoliation-syndrome
• earlier ocular surgeries or laser treatments
• intraocular tumors
• color abnormalities
• expected postoperative visual acuity lower 1.0
