Specialty Soft Lenses for Irregular Astigmatism
In today’s market of off-the-shelf contact lens products, practitioners sometimes forget about the custom products available for patients that fall outside of a normal refractive error range. Patients with high myopia, hyperopia, astigmatism, or those outside of the bell curve can be fit special custom soft lenses personalized to their needs.
Patients with keratoconus, corneal dystrophy or other types of irregular astigmatism have the same options. Soft lenses tend to be forgotten in these cases and can be a great resource for many of these patients. These lenses can provide great vision and comfort with just a few special measurements and a little effort.
The current methods of fitting soft lenses may provide instant results, but often come with drawbacks. Patients are often forced to sacrifice visual acuity or comfort due to the limitations of “off the shelf, “premade contact lenses. Those sacrifices are often not necessary, as custom lenses can accommodate large power ranges and corneal conditions.
When practitioner think of custom lenses, many think of a wide variety of base curves and extended power ranges. However, that is not the only parameter that can be customized. These lenses can be manufactured with:
- wide diameter ranges,
- customized center thicknesses,
- custom curves designs,
- standard bicurve,
- custom tri or quad curve peripheral systems,
- custom optic zones,
- reverse curves peripheral systems (amazing for oblate corneas that need flatter base and tighter edges),
- and a variety of special edge designs to accommodate the custom patient needs.
ABB Optical Group manufactures all of these custom lens designs in the newly re-released Concise Custom family of lenses.
