Avansee Preload1P is designed with the surgeon in mind

All Avansee lenses are manufactured from hydrophobic, highly cross‑linked, soft acrylic. There have been no reports of glistening since their launch in 2007.^1–3

IOLs were incubated in saline at 45 ± 1°C for 24 hours and then at 37 ± 1°C for a further 2.5 hours to allow glistening to form.⁴

Low PCO rate

The smooth lens surface and 360º square edge design, which extends around the lens including the optic-haptic junction⁶, are associated with reduced posterior capsule opacification (PCO) formation.^7,8

Unique haptics maintain space between optic and haptic, aiding adhesion between the anterior and posterior capsule, preventing PCO.⁸

Hydrophobic IOLs are associated with reduced risk of PCO, compared to hydrophilic IOLs.⁹

Excellent vision quality

The low asphericity of Avansee lenses means they provide a long depth of focus and are less influenced by IOL misalignment (decentration and tilt).^9,11

IOLs that have little effect on the spherical aberration of the eye can potentially improve the quality of vision by reducing the risk of coma aberration associated with IOL misalignment (decentration and tilt).

The asphericity of Avansee is -0.04μm.¹¹

Spherical aberration vs Coma aberration^13,14

Avansee lenses have a slight aspheric correction (-0.04µm), reducing the effect of spherical aberration compared to spherical IOLs.^9,11

Additionally, this aberration-neutral concept means the lens is less affected by coma aberration, which has a greater impact on IOLs with stronger aspheric corrections.^13,14

Over 1 million Avansee lenses sold since launch in 2007, with very low incidences of adverse events (0.009%) and serious adverse events (0.0009%).^15,16
