IT'S THE ONE WITH PROVEN HYDROPHOBIC ACRYLIC MATERIAL

There is no reason to block blue light

• Blocking blue light does not provide any proven benefit, and increases the risk of compromising scotopic vision and normal circadian rhythms.(6)
• Furthermore, multiple peer-reviewed studies have failed to find a link between age-related macular degeneration (AMD) and blue light exposure.(6)

Healthy blue light transmission is necessary for optimal scotopic vision(6)

Blue light provides 35% of scotopic sensitivity(6)	Blue-blocking IOLs reduce scotopic sensitivity up to 21%(6)

• Scotopic vision declines with age, even in healthy eyes without cataract or retinal disease.(6)
• Driving, mobility and peripheral vision problems have all been associated with reduced scotopic vision.(7)

Blue light is essential for healthy circadian rhythms(6)

Blue light is responsible for 55% of melatonin suppression(6)

• Circadian rhythms are normal 24-hour cyclic activities in the body that influence sleep pattern, mood, alertness, and body temperature.(6)
• Blue light helps regulate melatonin levels which influence circadian rhythms.(6)
• Blue light has been shown to regulate melatonin and enhance alertness even in blind persons.(8)

BETTER MATERIAL REDUCES CHROMATIC ABERRATION

What is chromatic aberration?

Chromatic Aberration Present	Chromatic Aberration Corrected

• Chromatic aberration is the uneven focusing of an optical system that causes different wavelengths of light to have different focal points.(9)
• Chromatic aberration of optical materials can be expressed by their Abbe number. A higher Abbe number is associated with less chromatic aberration and better optical performance.(10,11)
• Materials with low Abbe numbers and high chromatic aberration negatively impact contrast sensitivity.(10)

TECNIS® IOLs demonstrate lower chromatic aberration than AcrySof® IOLs
A higher Abbe number means less chromatic aberration and better photopic performance.(10)	At 30 cycles/degree (equivalent to 20/20), TECNIS® IOLs demonstrate 40% better contrast sensitivity than AcrySof® IOLs.(10) n=refractive index

BETTER MATERIAL NOT ASSOCIATED WITH GLISTENINGS AND CALCIFICATION

• Glistenings in IOLs may decrease visual acuity(12) and contrast sensitivity.(13)
• Temperature fluctuations of other IOLs have been shown to cause glistening formation.(14)
• TECNIS® IOLs are made with a proprietary cryo-lathing method that limits microvoid formation and high temperature fluctuations for reduced glistening formation.(14)
• The TECNIS® 1-Piece hydrophobic acrylic material is not associated with calcification and opacification found in hydrophilic acrylic IOLs.(15)

The clinical study conducted in 2002 and summarized in the labeling did not demonstrate a statistically significant improvement in contrast sensitivity. However, these more recent studies have shown statistically significant improvements in contrast sensitivity function with the TECNIS® IOL.

A comprehensive review and analysis of the published and unpublished studies demonstrates that the TECNIS® IOL provided a significant 38% (p<0.0001) overall improvement in contrast sensitivity results over a variety of control lenses with spherical optics.
