STAAR Surgical

Exciting new chapter in refractive surgery

EVO offers patients an exciting new chapter in refractive surgery:

  • Does not induce dry eye syndrome4
  • Rapid visual recovery3,6
  • Superb quality of vision1
  • Excellent night vision5
  • No risk of ectasia6
  • Improved quality of life5

STAAR’s exclusive, premium Collamer® material

EVO uses STAAR’s exclusive, premium Collamer® material

  • Collamer is derived from two words that describe the composition of the material: “Collagen” and “Copolymer”.
  • Collamer is a copolymer of poly-HEMA and collagen, that offers UV protection.
  • Collamer has a proven history of over 20 years with more than 2 million ICL lenses distributed worldwide.
  • Collamer minimizes inflammation, flare and cellular reaction.8,9

Why is the EVO ICL family of lenses* (EVO) a Game Changer?

  • High rate of patient satisfaction1
  • Preserves the cornea and crystalline lens3
  • Low rate of adverse events1
  • Outstanding safety and effectiveness1,2
  • No preoperative peripheral iridotomies (PIs)
  • Outstanding postoperative uncorrected visual acuity1

 * The EVO family of lenses includes EVO ICL, EVO Toric ICL, EVO+ ICL and EVO+ Toric ICL.

Great for you, great for your patients


The effectiveness of EVO is demonstrated by the high levels of postoperative uncorrected visual acuity, refractive predictability and stability1 enjoyed by patients. Efficacy Index is defined as UCVA (Uncorrected Visual Acuity) after treatment divided by CDVA (Corrected Distance Visual Acuity) before treatment (UCVA post/CDVA pre).

Refractive Stability

Excellent refractive stability.

IOP Stability

Intraocular pressure (IOP) is well controlled.


High predictability across a large diopter range.

Rotational Stability

Of 629 eyes implanted with EVO, only one eye with a toric lens required surgical repositioning for residual astigmatism (Data from U.S. FDA Clinical Trial).7

Excellent Night Vision

EVO provides postoperative improvement in mesopic contrast sensitivity (CS) with and without glare.5

Low Higher-Order Aberrations

Low induction of coma-like, spherical-like and total higher-order aberrations (HOA).10


Safety data suggest reduced rates of anterior subcapsular cataract and pupillary block relative to earlier models.1,7
