Outcome Measures

Primary Outcomes (1)

  • Mean Reduction in Cylindrical Power of the Eye

    Reduction in the cylindrical power of the eye is defined as the difference between the magnitudes of the preoperative keratometric cylinder and the residual refractive cylinder (referenced to the corneal plane).

    4 weeks after IOL implantation

Study Arms (2)

enVista Toric 0.9D intra ocular lens

Device: enVista Toric

enVista non-Toric (spherical) intra ocular lens

Device: enVista non-Toric (spherical)

Interventions

enVista Toric IOL

enVista Toric 0.9D intra ocular lens

enVista non-Toric (spherical) IOL

enVista non-Toric (spherical) intra ocular lens

Sampling MethodNon-Probability Sample
Study Population

The performance of the enVista Toric IOLs will be compared with that of enVista non-Toric (spherical) IOL in patients with pre-op corneal astigmatism \<1.0D. At least 384 eyes (n= 192 per lens type) from 3-4 Canadian centers will be investigated.

You may qualify if:

  • Males and Females subjects age 18 or older on the date of surgery
  • Implant of enVista Toric IOL and/or enVista non-Toric (spherical) IOL in at least one eye
  • Data available at least 4 weeks after IOL implantation
  • Eyes must qualify for the 0.9D toric lens based on the Barrett Toric Calculator (flipped axis must be less than 0.2D) (https://ascrs.org/tools/barrett-toric-calculator)
  • Study eyes were implanted with the 0.9D toric lens
  • Control eyes were not implanted with the 0.9D toric lens and implanted with a spherical (non-toric) equivalent instead

You may not qualify if:

  • History of uncontrolled or clinically significant ocular comorbidities for the treated eye(s) before the surgery (e.g., dry eyes, retinal pathology, etc.)
  • BCDVA of 20/25 or worse for the treated eye(s) after the surgery
  • Excessive IOL rotation \> 10 degrees (Toric IOLs only) for the treated eye(s) after the surgery
