Lenstec - Model SBL-2 - Segmented Bifocal Lens

The Lenstec SBL-2 provides both surgeon and patient a very high level of confidence based on the manufacturing tolerances and the availability of 0.25 Diopter power increments.  This process enables Lenstec to manufacture the SBL-2 to an industry leading ±0.11 Diopters of the intended power, allowing it to be distinguished as part of the Precision Series.    The SBL-2 comes with a true 2.0 diopter sector-shaped add with a seamless transition zone between the distance and near segments.

Several prospective studies have been performed on the SBL-2, with results identifying a high level of near, intermediate and distance vision, very limited amounts of visual side effects and extremely high patient satisfaction and spectacle independence ratings.
