Benefits of the Primus-HD® IOL

✔ Premium Glistening-Free Hydrophobic Material

Its high-purity hydrophobic acrylate (Grade "0" on the Miyata scale) eliminates the occurrence of glistenings and delivers superior optical transmission.

✔ Next-Generation Aspheric Optics

Featuring a negative aberration correction of –0.20 μ, it significantly enhances image quality and contrast sensitivity, particularly in low-light conditions.

✔ Convex Posterior Design

Promotes excellent optical quality and ensures a highly stable relationship with the posterior capsule.

✔ 360° Square-Edge Design

Increases the mechanical barrier effect against lens epithelial cells (LECs), significantly reducing the risk of posterior capsular opacification (PCO).

✔ Prosert® 1-Step Preloaded Injector

• 100% factory preloaded for a zero-touch technique.

• Dynamic 1.78 mm tips, suitable for micro-incisions of 2.0–2.2 mm.

• Rapid and highly controlled deployment.

• Zero adhesion between the optic and the haptics.

✔ Exceptional Stability via Modified C-Loop

The 1.5° angled haptic design keeps the lens perfectly centered and stable, even in large capsular bags or with anatomical variations.

Primus-HD® Yellow – Added Protection

The Yellow version features an integrated blue light filter). (390–470 nm).
This helps reduce retinal exposure to high-energy light without altering natural chromatic perception or visual quality.

Optical Performance

• High light transmission.

• Textured edges to minimize unwanted reflections ("edge glare").

• Excellent capsular adaptation with full 360° contact.
