The 1stQ Addon® Lens

One more surgery,
same lens

On top of the cataract surgery you already had,
discover a supplementary lens that adds near, intermediate and distance vision.

1stQ AddOn lens

After cataract surgery, why do you still need glasses?

Replacing the clouded lens with a monofocal IOL improves your vision,
but near vision often declines after monofocal IOL cataract surgery.

Putting glasses on and off becomes a daily hassle, again and again.

Even after a monofocal IOL,
freedom from glasses is possible.

The 1stQ AddOn® lens is an intraocular lens designed to improve near, intermediate and distance vision.
Placed in front of the existing IOL as a supplementary lens, the two lenses work together for optimal vision at every distance.
