EVO ICL Lenses* (EVO)

STAAR Surgical's phakic IOL for myopia with and without astigmatism

EVO Uses Advanced Technology to Provide Outstanding Safety and Effectiveness1,2

The novel 360 µm central port:

  • Eliminates the need for preoperative peripheral iridotomies (PIs)1
  • Lowers the risk of pupillary block and cataract1
  • Reduces office visits for the patient

An Exciting New Chapter in Refractive Surgery

Preserves the cornea and crystalline lens3
Does not induce dry eye syndrome4
Removable by a doctor
Rapid visual recovery3.5
No risk of ectasia5
No added complexity in future cataract surgery calculation6


The effectiveness of EVO is demonstrated by the high levels of postoperative uncorrected visual acuity.1

EVO uses an Exclusive, Premium Collamer® material

Collamer® is derived from two words that describe the composition of the material, which are “Collagen” and “Copolymer.”
Collamer® is a unique copolymer biocompatible material with properties that minimize inflammation, flare and cellular reaction.8,9
The Collamer® material is bonded with UV-absorbing chromophore into a poly-HEMA-based copolymer that offers UV protection.
Collamer® is exclusive to STAAR® Surgical. It has a proven history of over 30 years with more than 3 million ICLs distributed worldwide.

Important Safety Information for the EVO ICL Product Family:

The EVO ICL is indicated for phakic patients 21-45 years of age to correct/reduce myopia with up to 4.00 D of astigmatism with a spherical equivalent ranging from -3.00 to -20.0 D and with an anterior chamber depth (ACD) 3.0 mm or greater.

The EVO ICL is contraindicated in patients with a true ACD of <3.00mm; with anterior chamber angle less than Grade III; who have moderate to severe glaucoma, who are pregnant or nursing; less than 21 years of age; and who do not meet the minimum endothelial cell density (ECD) listed in the Directions For Use (DFU).

A summary of the relevant warnings, precautions and side effects: Endothelial cell loss, corneal edema, cataract, narrowing of the anterior chamber angle, pupillary block, increased intraocular pressure, glaucoma, secondary surgery to reposition, replace or remove the ICL, loss of BSCVA, increase in refractive astigmatism, glare and/or halos, pigment dispersion, iris transillumination defects, endophthalmitis, hypopyon, corneal endothelial damage, ICL dislocation, cystoid macular edema, iritis, retinal detachment, vitritis, and iris prolapse.

Please review the DFU for complete safety and other information before performing the clinical procedure.
