Description
The HOYA Vivinex™ Toric IOL (Model XY1AT2) is a specialized intraocular lens designed to correct astigmatism during cataract surgery. Crafted from hydrophobic acrylic, this lens offers a glistening-free experience, providing clear vision with reduced visual disturbances. Its advanced material includes UV and blue light filters, enhancing eye protection.
Optic and Haptic Design
- Optic Design: The lens features a biconvex optic with a square, thin, and textured edge. Its anterior aspheric and posterior toric designs contribute to precise visual correction.
- Haptic Design: The textured-rough haptic surface ensures enhanced stability within the eye, maintaining the lens's position effectively.
Dimensions and Power Range
- Optic Diameter: 6.00 mm
- Overall Length: 13.00 mm
- Spherical Power Range: +10.00 to +30.00 D in 0.50 D increments
- Cylinder Power: Ranges from 1.00 to 6.00 D at the IOL plane, with specific increments for precise correction.
Optical Constants
The lens's optical constants are finely tuned, with a nominal A-constant of 118.9 and optimized constants for various calculation methods, ensuring accurate surgical outcomes.
Injector System
The preloaded multiSert™ injector system offers versatility with single-handed push and two-handed screw injection options. It includes an adjustable insert shield for precise injector tip depth, with a recommended incision size of 2.20 mm.
Clinical Performance
The HOYA Vivinex™ Toric IOL demonstrates exceptional clinical performance with over 96% of lenses rotating ≤5° post-surgery, ensuring stable alignment. It shows a low incidence of posterior capsule opacification (PCO) and maintains optical quality even in complex procedures.
Intended Use
This lens is intended for implantation in the capsular bag during cataract surgery, suitable for patients needing refractive astigmatism correction. Its design supports duet procedures, working effectively with supplementary IOLs.
