Cristalens Symbiose® Premium Intraocular Lens
Cristalens Symbiose® is an advanced multifocal intraocular lens (IOL) designed to restore high-quality vision at multiple distances after cataract surgery or refractive lens exchange. The lens uses a sophisticated diffractive extended depth-of-focus optical design that works synergistically between both eyes to deliver balanced distance, intermediate, and near vision.
Unlike conventional multifocal lenses, the Symbiose concept relies on binocular complementarity, where each eye is optimized for different visual ranges, allowing patients to experience seamless vision throughout daily activities such as reading, computer work, and driving.
The lens is manufactured using hydrophobic acrylic material with aspheric optics that partially compensate for corneal spherical aberration, improving contrast sensitivity and overall visual quality.
Key Features
Extended Depth of Focus (EDOF) Multifocal Optics
Binocular Complementarity Design
Aspheric Optics with Negative Spherical Aberration
Hydrophobic Acrylic Material
360° Square Edge Design for PCO Reduction
Preloaded Injection System
Micro-incision Compatible (<2.0 mm)
These design features provide stable implantation, improved postoperative visual outcomes, and enhanced patient satisfaction.
Optical Concept
The Symbiose lens concept works through two complementary optical profiles:
Symbiose MID
Optimized for distance and intermediate vision
Ideal for computer work, dashboard viewing, and daily tasks
Symbiose PLUS
Optimized for intermediate and near vision
Enhances reading, smartphone usage, and fine visual tasks
Together, the two lenses create a full range of functional vision, reducing dependency on spectacles.
