Basis Z trifocal

hydrophilic non-preloaded yellow

The Basis Z trifocal is an aspheric capsular bag lens providing trifocal function in cataract or refractive lens exchange – with +3.5 D addition for near vision and EPS technology for visual acuity at all distances while minimizing dysphotopsias.

The Basis Z trifocal
sophisticated design, proven application.
