enVista® Toric Intraocular Lens 

ONE-PIECE HYDROPHOBIC ACRYLIC TORIC IOL

Lock in superior rotational stability1

Unique haptics are designed to secure a predictable astigmatism correction

  • Glistening-Free Hydrophobic Acrylic
  • The ideal combination of stable performance and predictability
  • Aberration-Free Aspheric
  • Fenestrated, step-vaulted haptics with 56° Contact angle and square posterior edge optic are designed to optimize 360° Capsular contact2
  • 360° posterior square edge with haptic-optic junction designed to minimise PCO
  • Polished for a smooth optic surface

Unique fenestrated, step-vaulted haptics with 56° contact angle are designed to maximise stability

• 91 % of patients had ≤ 5° rotation from day of surgery to 6 months1

• 3° absolute mean rotation at 6 months1

• 0.28 mm mean decentration1
