Collamer®, Toric, and Silicone IOL Models - Intraocular Lens Cataract Solutions
STAAR® Surgical Company develops, manufactures, and distributes world-wide an array of foldable intraocular lenses ( IOLs). The company offers various IOLs that are used in cataract surgery, each with its own set of advantages.
In order to satisfy various cataract surgical correction needs, from basic cataract removal to astigmatic surgical correction, STAAR Surgical Company has designed distinct IOL models. The Afinity™ Collamer IOL (available in both single piece and 3-piece models) is highly biocompatible. The STAAR Toric™ IOL is designed for cataract patients with astigmatism between 1.5D and 3.5D. STAAR Surgical Company's silicone IOLs are available in a single piece, 3-piece and aspheric models.

Afinity Collamer IOL
Created for the treatment of cataracts through surgical correction, the Afinity line of IOLs from STAAR Surgical Company are comprised of the unique, biocompatible Collamer material.
The Collamer Advantage
Exclusive to STAAR Surgical Company, Collamer is a unique lens material that is composed of collagen, a UV-absorbing chromophore, and a poly-HEMA based copolymer .1 The Afinity Collamer IOL produces excellent optical performance and achieves significant biocompatibility.
Exceptional Quality of Vision
- Collamer lenses provide exceptional quality of vision. 2, 3
- Compared to other lens materials (including acrylic and PMMA), Collamer has less internal reflectance, reducing or eliminating the occurrence of glare and halos. 4
- Collamer induces fewer higher order aberrations than other lens materials. 2
Collamer IOL
- Index of refraction: 1.44
- No visible glare, halos or ghosting
Silicone IOL
- Index of refraction: 1.41
- No visible glare, halos or ghosting
Acrylic IOL
- Index of refraction: 1.55
- Visible glare, halos and ghosting
[ back to top ]
Significant Biocompatibility
- Collamer possesses inherent biocompatibility. 4
- The lens material attracts fibronectin. A monolayer around the Collamer IOL shields it from the body's immune system. 4, 5
- The collagen in Collamer produces a slight negative ionic charge, repelling protein attachment on the lens surface.4
Acrylic Lens : (Magnified 1,000 times) After one-minute of exposure to protein mixture, note the dense existing protein deposition.
Collamer Lens : (Magnified 1,000 times) After one minute of exposure to the same protein mixture, note the near absence of protein on the Collamer IOL.
Acrylic IOL vs. Collamer IOL
Excellent for Patients with Specific Health Issues
- Collamer lenses do not encounter the same problems that other lens materials do in patients with specific health conditions including diabetes, chronic uveitis, iritis, and other inflammatory conditions of the anterior chamber. 6
- Collamer is appropriate for patients precluded from other lens use due to specific health conditions impacting the eye. 6
- The unique properties of Collamer do not induce long term "flare," decreases inflammation, and prevents cellular attraction. 6, 7
Patient Satisfaction
- Collamer lenses deliver superior outcomes and satisfaction among a wide range of cataract surgery patients. 1, 6

STAAR Toric Silicone Single Piece IOL
The forerunner in toric lens design: Effective, safe, and reliable vision correction in one innovative, astigmatic cataract procedure.
- Injectable single-piece STAAR TORIC IOL provides both cylindrical and spherical optic correction
- Incorporated toric optic corrects preexisting astigmatism, eliminating need to alter corneal curvature
- Improves uncorrected vision that could negatively affect visual acuity
- Available in a range of spherical powers with cylindrical adds of 2.0D and 3.5D
- At the corneal plane, the optics of the 2.0D and 3.5D lenses correct 1.4D and 2.3D of astigmatism, respectively
Intuitive lens design provides a smarter approach to astigmatic cataract surgery
- Astigmatic correction applied to the intraocular lens eliminates need for additional procedures
- Frosted plate haptics and large fenestrations promote bioadhesion for capsular bag stability
- The STAAR TORIC IOL is available in 10.8 mm and 11.2 mm sizesideal for implantation in the capsular bag
- Longer length accommodates eyes with longer axial length and may aid rotational stability12
- Plate style design allows for simplified injection and easy placement
The benefits of silicone lens composition are inherently clear
- STAAR silicone lens technology induces fewer higher order aberrations than acrylic lenses11
- The lower refractive index of silicone lenses compared to acrylic lenses results in lower incidence of halos, glare, and ghosting
- Light is better transmitted through the silicone lens but commonly reflected through the acrylic lens
Design and placement of the STAAR TORIC IOL reinforces rotational stability
- Improved, longer STAAR TORIC IOL provides excellent rotational stability12
- Improved design helps prevent IOL rotation associated with increased axial length
- Planar plate design resists rotation as compared to loop lens designs
- Provides consistent axial position
- Large fenestration allows fibrous lens epithelial cells to migrate through and around the lens hole to lock the lens to the equator of the capsular bag for added stability
Methods and techniques for predictable, high quality outcomes
- The STAAR TORIC IOL is best used in cataract patients with 1.5 to 3.5 diopters of regular preexisting astigmatism ("bow-tie" or "wedge" patterns)
- Surgeons are advised to measure astigmatism with keratometry to determine the appropriate power to best reduce postoperative refractive cylinder
- Corneal topography and refraction should also be used to verify the steep corneal meridian
- To ease insertion, the MICROSTAAR Injector can be used to guide the lens through the incision
- Cylinder axis marks on the lens allow precise alignment with the steep corneal meridian
Optimize your procedure using the "PreVize® Optimized" Toric Calculator, available at STAARToric.com
- This exclusive tool includes:
- A surgical worksheet that includes preoperative data
- A list of suggested surgical powers
- A clearly labeled illustration of the exact placement of the STAAR Toric IOL
Position to Steep Corneal Meridian
Spherical power: visit www.staartoric.com to calculate IOL powers and lens orientation.
Cylinder Power Selected According to Corneal Astigmatism Nomogram as Follows:
Nomogram assumes astigmatically neutral surgery.
1With the Rule, steep corneal meridian between 46 to 134; Against the Rule, steep corneal meridian between 0 to 45 and 135 to 180.
2Approximate value of the equivalent IOL cylinder power at the cornea.
