i-stream toric

hybrid lens for the correction of astigmatism


The 30-40 % of patients wittl cataract has an astigmatism higher than 1 diopter.
lf this astigmatism isn’t correct, the patient needs glasses in the post-operatory.
i-stream toric increases the possibility of a vision without glasses.
i-stream toric is meant to offer solutions for patients with both, cataract and astigmatism,
by the followings features:
• The range of cylinders covers aver 80% of requests.
• The design an d 1he hybrid nature of the IOL offers an easy positioning an the axis for the surgeon.
• The wide contact surface and the stabilrty are effective and safe aver time.



i-stream toric s made of an ultra-purified acrylic monomer wittl a 25%
of water content and an hydrophobic surface.
• This combines the advantages of hydrophobic and hydrophilic IOLs
• The material is elastic and resistant to manipulation, it is extremely biocompatible
with an high UV rays absorption
• The innovative Natura! Yellow fllter permtts to fltter effectively the harmful blue light
that can’t reach the retina, wtthout altering color perception and contrast sensitivity

 i-stream toric lens


i-stream toric can be injected through incisions smaller than 2,0 m m. This kind of incisions has many advantages:
• Reduction of induced postoperative astigmatism
• lnflammatory risk minimization compared to incisions larger than 2.0mm
• Reduction of risk of endothelialloss compared
• Rapid closure of corneal incisions to incisions bigger than 2.0mm
• Reduced postoperative healing times
• Patient’s satisfaction



The i-stream toric geometry has been designed to maximize your patient’s visual performances. The IOL has a biconvex optic with a precise negative spherical aberration: -0,26μm. i-stream toric permits to compensate the positive spherical aberration of the cornea, bringing back your patient’s eye to an ideai condition: a young and emmetropie eye.
