The Optics & All about the Haptics
Riyan 3 Piece is a UV light-absorbing posterior chamber hydrophobic acrylic lens designed to be implanted in the capsular bag following extra capsular cataract extraction. The opticis biconvex design with 6mm Aspheric design as well as spherical optics, with 360° Square Edge to reduce PCO, and 13mm / 14mm overall size.
Polyvinylidene fluoride monofilament haptics, PVDF have better shape recovery and loop memory compared to other haptic materials. Very malleable and resistant, PVDF haptics are designed for better capsular bag stability and to eliminate capsular bag stretching. PVDF haptics create a better flange than PMMA haptics, and can prevent conjuctival erosion during intra scleral haptic fixation.
Cap C haptics design with 5° angulation are best suited to the capsular bag for long term optimal centration, refractive stability and minimal zonular stress
