Adjustable IOLs use the two forces of vitreous movement and ciliary muscle contraction, as well as the convexity created when moving forward, to achieve the maximum forward movement and sufficient convexity needed to ensure clear near vision. Fluoroscopy is designed so that the lens moves like a “sail”, and with the movement of the vitreous humor, it moves forward to the maximum to obtain near vision, and relaxes to a flat state to obtain clear vision at intermediate and long distances. In other words, patients can see like normal people, which facilitates their daily work and life needs such as driving and reading after surgery, and improves their quality of life, which is an advantage that cannot be achieved by ordinary IOLs. Features and advantages of Fluorovision Free Adjustable IOL: 5-degree angular loop design, 5-degree angular loop forward tilt, which facilitates forward movement when adjusting the lens. Four-touch loop and right-angle edge design, the contact area between the four-touch angle and the posterior capsule is about 1 square millimeter. Compared with traditional IOLs, this design makes the ciliary muscle action force concentrated on the four-touch angle, which increases the unit area pressure, reduces the ciliary muscle action force requirement during crystal adjustment and expands the surgical population. The four-contact design reduces the contact area between the lens and the capsular bag, and together with its own right-angle edge design, it significantly reduces the incidence of PCO. Acrylic resin material (26% water content ) good biocompatibility, optical properties and memory. Higher precision Commonly used diopters (18D-25D) in 0.2D increments, improving the precision of lens refractive index selection. 5.75mm optical zone Prevents the occurrence of glare and halos. Highly demanding surgical technique: ultrasound emulsification technique, complete annular tearing capsule technique, no intraoperative complications.
