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.(11)
  • Furthermore, multiple peer-reviewed studies have failed to find a link between age-related macular degeneration (AMD) and blue light exposure.(11)

Healthy blue light transmission is necessary for optimal scotopic vision(11)

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

Healthy blue light transmission graphs

  • Scotopic vision declines with age, even in healthy eyes without cataract or retinal disease.(11)
  • Driving, mobility and peripheral vision problems have all been associated with reduced scotopic vision.(12)

Blue light is essential for healthy circadian rhythms(11)

Blue light is responsible for 53% of melatonin suppression(11)

Blue light is responsible for 53% of melatonin suppression(11)

  • Circadian rhythms are normal 24-hour cyclic activities in the body that influence sleep pattern, mood, alertness, and body temperature.(11)
  • Blue light helps regulate melatonin levels which influence circadian rhythms.(11)
  • Blue light has been shown to regulate melatonin and enhance alertness even in blind persons.(13)


What is chromatic aberration?

Chromatic Aberration PresentChromatic Aberration Corrected
Chromatic Aberration Present and Corrected Examples
  • Chromatic aberration is the uneven focusing of an optical system that causes different wavelengths of light to have different focal points.(14)
  • 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.(15,16)
  • Materials with low Abbe numbers and high chromatic aberration negatively impact contrast sensitivity.(15)
TECNIS® IOLs demonstrate lower chromatic aberration than Competitor IOLs

TECNIS IOLs demonstrate lower chromatic aberration than Competitor IOLs

A higher Abbe number means less chromatic aberration and better photopic performance.(15)

At 30 cycles/degree (equivalent to 20/20), TECNIS® IOLs demonstrate 40% better contrast sensitivity than other IOLs.(15)
n=refractive index


  • Glistenings in IOLs may decrease visual acuity(17) and contrast sensitivity.(18)
  • Temperature fluctuations during the molding process of other IOLs have been shown to cause glistening formation.(19)
  • TECNIS® IOLs are made with a proprietary cryo-lathing method that limits microvoid formation and high temperature fluctuations during the molding process for reduced glistening formation.(19)
  • The TECNIS® 1-Piece hydrophobic acrylic material demonstrates less calcification and opacification than found in hydrophilic acrylic IOLs.(20,21)

Indications and Important Safety Information



Federal law restricts this device to sale by or on the order of a physician.


TECNIS® lenses are indicated for the visual correction of aphakia in adult patients in whom a cataractous lens has been removed by extracapsular cataract extraction. These devices are intended to be placed in the capsular bag.


Physicians considering lens implantation under any of the conditions described in the Directions for Use labeling should weigh the potential risk/benefit ratio prior to implanting a lens.


Do not resterilize or autoclave. Use only sterile irrigating solutions such as balanced salt solution or sterile normal saline. Do not store in direct sunlight or over 45°C.

Adverse Events

Adverse events occurred at rates between 1.6% and 3.3% during the clinical trials for TECNIS® IOLs or their “parent” IOLs. These events included macular edema, endophthalmitis, anterior lens tissue ongrowth, lens dislocation, hypopyon, corneal edema, iritis, hyphema, secondary glaucoma, and secondary surgical intervention.
