Description
The HOYA TORIC IOL XY1AT4 is a specialized intraocular lens designed to enhance visual outcomes for cataract surgery patients with pre-existing corneal astigmatism. As part of the Vivinex™ Toric IOL family, this lens offers precise correction for patients with approximately 1.56 diopters of astigmatism, making it suitable even for those undergoing combined cataract and iStent surgery.
Key Features
-
Material and Design: Crafted from hydrophobic acrylic, the lens is glistening-free and incorporates UV- and blue light filtering. Its biconvex optic design features an aspheric anterior surface and a toric posterior surface, complemented by a textured optic edge to enhance performance.
-
Dimensions: The lens has an optic diameter of 6.00 mm and an overall length of 13.00 mm, providing a stable and comfortable fit within the eye.
-
Haptic Design: The textured-rough haptic surface ensures secure positioning, contributing to the lens's renowned rotational stability.
Optical Performance
The HOYA TORIC IOL XY1AT4 boasts a comprehensive power range, with spherical powers from +10.00 to +30.00 D and cylinder powers at the IOL plane from 1.00 to 6.00 D. This flexibility allows for tailored correction, enhancing uncorrected visual acuity and reducing postoperative refractive astigmatism.
Implantation System
Equipped with the multiSert™ preloaded injector system, the lens can be implanted through a 2.20 mm incision, ensuring a minimally invasive procedure. The system's precision aids in accurate axis alignment, crucial for optimal astigmatism correction.
Clinical Benefits
-
Rotational Stability: Clinical studies demonstrate that over 96% of these lenses rotate ≤5° post-surgery, ensuring consistent visual performance.
-
Posterior Capsule Opacification (PCO): The lens's square optic edge design significantly reduces PCO, with lower rates observed compared to other IOLs like AcrySof® IQ over a three-year period.
-
Visual Outcomes: Patients experience significantly better visual acuity, with 78% achieving postoperative refractive astigmatism of 1.0 D or less, compared to 11% in non-toric IOL groups.
Conclusion
The HOYA TORIC IOL XY1AT4 stands out for its advanced design and proven clinical performance, offering cataract patients a reliable solution for correcting astigmatism and achieving superior visual clarity. Its innovative features and robust clinical outcomes make it a valuable choice for enhancing postoperative satisfaction.
