On January 6, 2025, the Loong Crystal™ PR phakic intraocular lens (Registration No.: 国械注准20253160001), developed by Eyebright Medical, received approval from the National Medical Products Administration (NMPA) through the Special Review for Innovative Medical Devices. Designed for myopia correction in adults with phakic eyes, this lens marks a significant milestone after years of research and clinical trials, enhancing Eyebright Medical's product pipeline and offering a new option for myopic patients.
Phakic intraocular lens implantation is a leading option for intraocular refractive surgery, noted for its minimal ocular trauma, reversibility, and predictability. The Loong Crystal™ PR has achieved significant advancements in materials and design, with its unique benefits validated through clinical trials.
Patent-protected innovative materials provide enhanced stability
The Loong Crystal TM PR phakic intraocular lens utilizes patented Balacrylic™ balanced acrylic material, demonstrating outstanding overall performance
Balacrylic™ balanced acrylic material
High Refractive Index
Increases optical zone diameter, reduces thickness, and minimizes lens volume
Excellent Elastic Modulus
Provides superior mechanical strength and support, with excellent implant unfolding performance and long-term stability of the arch height
Moderate Water Content
Enhances resistance to deposits and calcification, ensuring long-term material stability within the eye
Meticulously crafted design creates the beauty of a lens-free experience
Wider Arch Height
The phakic intraocular lens fits within the limited space in front of the natural lens, reducing anterior chamber burden
Enhanced Optical Zone
With Balacrylic™'s high refractive index, the Loong Crystal™ PR lens increases optical zone diameter while remaining thin, featuring a flatter posterior surface and broader peripheral arch height
Improved Visual Quality
Insufficient optical zone diameter in phakic intraocular lenses can cause glare and halos
Loong Crystal™ PR Advantage
Featuring a 6.0mm large optical zone and high-order aspheric zero spherical aberration design, it minimizes additional aberrations. Clinical trials confirm a significant reduction in postoperative glare incidence
Personalized Refractive Surgery Option
The diameter of the human ciliary sulcus varies, and precise size segmentation helps match different eye shapes
Loong Crystal™ PR Variety
With 10 models available in 0.3mm increments, it offers more personalized and refined choices for clinical applications
Long-term Intraocular Stability
Postoperative arch height reduction in phakic intraocular lenses can increase the risk of contact with the natural lens and affect refractive power
Loong Crystal™ PR Stability
With the mechanical stability of Balacrylic™ material, clinical trials show smaller changes in central and peripheral arch height, resulting in more stable residual refractive power
Phakic intraocular lens implantation surgery has become one of the mainstream myopia correction surgeries. The Loong CrystalTM phakic intraocular lens developed by Eyebright Medical Technology (Beijing) Co., Ltd. is based on a number of innovative technologies. It is expected to challenge the long-standing dominance of the ICL products of Staar Company in the Chinese and global markets, providing a new option for patients undergoing intraocular refractive correction surgery.
