Toric intraocular lens Precizon 575

astigmatismpresbyopia

Tolerance for misalignment Natural vision at all distances Reducing glare and halos The Precizon Presbyopic uses two patented technologies in its optic. The first one is transitional conic toric (TCT) technology which makes the lens more forgiving to decentration during surgery with less loss of quality of vision. The second is continuous transitional focus (CTF) technology which offers your patient a full range of vision from near to infinity with a smooth continuous transition. CTF This lens is designed with CTF, where a multiple segments optic on the anterior surface achieves a smooth transition from far to near focus. This transition offers a constant defocus between the two sharp focal points, delivering excellent intermediate vision. TCT A TCT optic is the foundation of astigmatism correction. A TCT optic is tolerant of misalignment because different conic constants are calculated, not only on the horizontal and vertical axis, but also between 0° and 90° degrees. Designed for.. Natural vision at all distances The transitional zones of the CTF optic offer a full range of vision from near to infinity with a smooth continuous transition. The CTF aspheric surface forms a broad beam of light, a zone with an enhanced depth of focus with uninterrupted high-quality images for the brain to translate into clear vision at all distances. Tolerance of misalignment In a significant percentage of cases, IOLs tend to rotate a few degrees before they stabilize. This leads to a loss of quality of vision in regular toric IOLs.
