Aspheric Hydrophobic Preloaded IOL I-stream is made of a new generation hydrophobic material which elasticity has been maximized and water content has been minimized. A better elasticity can absorb thermal contraction and dilatation due to increase or decrease of the temperature. This characteristic avoids IOL's material fragmentation and microvacuoles formation that could degenerate into glistening developing.
I-stream's design has been made to maximize your patient's visual performances. The IOL has biconvex optic with a precise negative spherical aberration: -0.26µm. This amount is exactly needed to compensate the positive spherical aberration on the cornea, bringing back your patient's eye to ideal condition : the one of young and emmetropic eye.
I-stream's MTF graph is the result of such a fine geometry study. Clinical laboratory studies demonstrate that the high quality of the optics lead to a better depth of field and excellent contrast sensitivity in each illumination context.
