Exceptional visual performance can be a reality for patients with even significant astigmatism. At Art Optical we provide a full range of lens options for your astigmatic patients.
Typically when the prescription exceeds 2.00D of with-the-rule corneal cylinder, the percentage of success with a spherical design decreases. As corneal cylinder increases, a spherical base curve will typically become more uncomfortable and the physical fit will appear less acceptable.
Intended for:
- Back Torics
- Bi-torics
- Front Torics
Aspherics
From 2.00D to 3.50D of corneal cylinder, with an equal amount of spectacle cylinder, the Boston® Envision design is a good lens of first choice. The bi-aspheric, junctionless posterior surface of Envision provides good patient comfort and better physical alignment than a spherical base curve.
Back Torics
Back toric lens designs are typically used when the corneal cylinder exceeds 3.00D and the amount of corneal versus spectacle cylinder are relatively equal.
Bi-torics
Bi-toric designs are used when the corneal cylinder exceeds three diopters and there is a substantial difference between the amount of corneal and spectacle cylinder. Having a substantial difference in toricity between the corneal and spectacle cylinder will normally not work with back toric lens designs. A bi-toric lens design will achieve the best lens to cornea fitting relationship and compensate for the calculated residual cylinder on the front surface.
Front Torics
It may be necessary to fit a front toric design for patients who have a spectacle cylinder with little or no corneal cylinder. This will generally result in residual cylinder, causing visual difficulties with a basic spherical lens design. This lens has a toric anterior surface with a spherical posterior surface and a prism ballast to orient the lens in the desired position.
