New PureVision Toric from Bausch & Lomb
The PureVision family of contact lenses is growing with the introduction this month by Bausch & Lomb of the PureVision Toric contact lens.
The new PureVision Toric contact lens offers patients with astigmatism the outstanding health and comfort of Bausch & Lomb's silicone hydrogel technology with Advanced Lo-Torque design to deliver exceptional vision.
More importantly, the aspheric anterior surface reduces spherical aberrations, while the posterior toric surface corrects cylindrical error.
In a clinical comparison of patients fitted with PureVision Toric contact lenses, patients had a significant reduction in spherical aberrations.
In addition to the reduction in spherical aberrations, the PureVision Toric contact lens offers the proven design features of Europe's leading hydrogel toric lens, Bausch & Lomb's SofLens66 Toric:
- a uniform midperipheral thickness at the apex, center and base of the optic zone;
- anterior and posterior optic zone diameters adjusted to minimize variations in thickness;
- prism ballasting that stabilizes geometry with a 360-degree comfort chamber.
In a clinical comparison to the SofLens66 Toric contact lens, there were no significant differences in primary gaze orientation or in rotational recovery, meaning practitioners can expect the same predictable orientation and ease-of-fit with PureVision Toric lenses as they have experienced with SofLens66 Toric lenses.
PureVision Toric and single vision contact lenses offer exceptional ocular health for patients whether worn as a daily lens, continuous wear or as a flexible wear lens. In a clinical comparison to PureVision single vision lenses, there were no significant differences for PureVision Toric with respect to comfort, dryness, or lens cleanliness.
With Bausch & Lomb's innovative AerGel technology, the PureVision lens silicone hydrogel material offers high oxygen permeability and excellent fluid transport. The advantages to wearers includes:
- an optimal ocular environment for healthy, comfortable contact lens wear;
- oxygen transmission comparable to wearing no contact lenses;
- a reduction in the risk of hypoxic stress such as edema, redness and nevascularization.
The additional benefits of the PureVision lens material includes the ability to minimize dehydration for less dryness, while the unique Performa surface process contributes to exceptional comfort by helping to repel debris and protein deposits.
