Both are preloaded IOL injector systems that allow quick, accurate and consistent IOL placement. They differ in two main parts, the lens and the injector.

Lens

Both lenses are manufactured from the same UV-absorbing, hydrophobic, soft acrylic material, which is glistening free and has an excellent long-term safety record. However, the AvanseePreset contains a 3-piece (3P) lens, whereas the Avansee Preload1P utilises a 1-piece (1P) lens. The 1P lens can be injected through smaller incisions (2.2–2.4mm)¹, compared to the 3P lens (2.4–3.0mm)².

Injector

The injectors share many common features, but have been specifically designed to partner their particular lens. The Avansee Preload1P injector is based on the original design of AvanseePreset. The unique plunger allows great control and lens stability during IOL insertion. The angled nozzle consistently releases the lens in the correct position (see Control).

For detailed instructions, please see the technical guide.

Plunger cannot be removed from eye

• Push the plunger fully forward, ensure the bevelled nozzle is pointing down and try to remove the plunger again.

Trailing haptic is not released into the eye

• The plunger has not been pushed fully forward, so the haptic is stuck between the plunger and the nozzle.The plunger should be pushed forward to release the haptic.

Plunger has been moved backwards

• This increases the possibility of further problems. Therefore, the product should be discarded and a new injector should be used.

The ideal IOL should:

• Provide high levels of corrected visual acuity (CVA)
• Be fully preloaded into an advanced injection system, allowing fast, reliable, reproducible, and controlled insertion through a small incision with a low risk of infection, and reduced levels of failure/wastage
• Quickly and fully regain its mechanical and optical properties after injection
• Assume a stable position within the eye and have a low risk of misalignment
• Experience little or no impact on visual function at common levels of misalignment
• Be associated with a relatively low risk of post-operative complications, such as posterior capsule opacification (PCO) and endophthalmitis
• Have a low propensity for glistenings and general deterioration over time

• +6.0 to +26.0 dioptre
• +6.0 to +10.0 dioptre (1.0D increments)
• +10.0 to +26.0 dioptre (0.5D increments)

Yes

Yes, Avansee does not contain metal.

In clinical practice, the average displacement observed for IOLs in normal eyes is 30 ± 0.16mm and the average tilt is 2.62 ± 1.14°.³

Optics made from a stable, uniform and highly cross-linked polymer are less likely to allow water to gather into the microvoid of the material. Therefore, they are less susceptible to glistening and/or whitening.

Avansee undergoes a stringent manufacturing process that ensures a uniform, high density of cross linkages in the optic polymer.

Compared to some other IOLs, Avansee has a low propensity to absorb water due to changes in temperature⁴ (see Confidence).
