Softec HDY: Unmatched Precision, Clarity, and Enhanced Protection
Lenstec’s SOFTEC HDY intraocular lens (IOL) integrates cutting-edge blue light filtration with high-precision optics to enhance visual clarity and offer potential retinal protection.
By merging advanced optical engineering with blue light filtering technology, the SOFTEC HDY provides a comprehensive solution for patients seeking both superior visual performance and potential photoprotective benefits.
Material Stability and Longevity
Manufactured using a material that demonstrates exceptional stability, the SOFTEC HDY withstands prolonged sunlight exposure without compromising optical quality. Accelerated aging studies, conforming to ISO photostability standards, simulate over 20 years of sunlight exposure, confirming the IOLs resilience and long-term efficacy.
Enhanced Refractive Precision with 0.25D Power Increments
Lenstec’s SOFTEC HDY, part of the SOFTEC HD portfolio of IOLs, has elevated the industry standard in Iens power accuracy with 0.25D power increments, offering greater refinement than conventional 0.50D steps. Precision Series Labelling provides increased lens accuracy and empowers surgeons to fine-tune vision correction with confidence. This leads to sharper, more predictable outcomes and improved patient experience and satisfaction.
Blue Light Filtration: Scientific Considerations
Since the 1980s, the incorporation of blue light filtering chromophores in IOLs has been extensively studied. Blue light (wavelengths 400–500 nm) is implicated in circadian rhythm regulation and cognitive function. However, concerns regarding excessive exposure, particularly from artificial sources such as LED screens, have spurred ongoing discussions regarding its potential impact on retinal health and sleep patterns.
Blue light filtering IOLs aim to reduce retinal exposure to high-energy visible light. While some clinical studies suggest potential benefits for retinal protection, systematic reviews indicate limited evidence supporting significant advantages over non-filtering lenses in terms of contrast sensitivity, macular degeneration progression, or sleep disturbances.
360-Degree Square-Edge Barrier for Posterior Capsular Opacification (PCO) Prevention
Posterior capsular opacification (PCO) remains a common factor in post operative cataract surgery, often necessitating Nd:YAG laser capsulotomy. The SOFTEC HDY features a full 360-degree square-edge design, offering a continuous barrier which slows down lens epithelial cell migration. Compared to IOLs with partial square-edge designs, this advanced configuration helps mitigate PCO development, reducing post-surgical interventions and preserving long-term visual outcomes.
Key Features & Benefits
- Advanced Optical Performance: The SOFTEC HDY is engineered to address both spherical aberration and defocus, key determinants of visual quality.
- Defocus Sensitivity: Even a minor defocus of 0.25D can significantly impact visual acuity, often more than spherical aberration or higher-order aberrations combined.
- Pupil Diameter Independence: Unlike spherical aberration, defocus effects remain consistent regardless of pupil size.
- Optimized Visual Quality: Combines blue light filtration with correction of spherical aberration and defocus for enhanced contrast sensitivity.
- Long-Term Stability: Demonstrated resistance to photodegradation ensures sustained optical performance.
- Enhanced Accuracy for Superior Clinical Outcomes: 0.25D increments provide precision in refractive targeting.
- Surgical Efficiency: Designed for compatibility with standard surgical procedures and instrumentation.
Streamlined Surgical Handling for Efficiency
Engineered with an “always right-way” design, the SOFTEC HDY simplifies lens handling and implantation, minimizing intraoperative complexity. This intuitive design enhances predictability and efficiency, making it particularly advantageous in high-volume surgical environments, where precision and workflow optimization are critical.
Regulatory Excellence & Global Quality Assurance
The SOFTEC HDY meets the highest international regulatory standards, including:
- CE Certified (EU 2023/607)
- BSI Registered
- ISO-Compliant Quality System Certification
These accreditations reinforce the reliability, safety and global acceptance of SOFTEC HDY as a premium monofocal IOL solution.
User Feedback
“For over 10 years, the Lenstec Softec HDY has been my monofocal IOL of choice. The availability of IOLs in 0.25D power steps through the common power ranges (+15 to +25), in combination with manufacturing tolerances that exceed ISO industry standards, means that I can be highly confident of achieving excellent refractive targeting outcomes and high levels of patient satisfaction. The lens is easy to use and implant, plus it remains very stable within the eye. Overall, I have been highly impressed and satisfied with the Softec HDY”.
