Implants for Astigmatism-Advanced Technology

We are very pleased to report that we now can offer the benefits of the Toric Intraocular Lens to many more of our patients. Starting next month we will have available 4 new astigmatism powers. This means we can correct astigmatism of up to 4 Diopters.  The unique design of a toric IOL makes it possible to reduce or eliminate astigmatism and significantly improve uncorrected distance vision following cataract surgery.  Toric IOLs provide significantly improved distance vision and may reduce the need for corrective lenses compared to a traditional monofocal IOL. 

If an eye has astigmatism it means that eye does not focus light to a single point; instead the eye focuses light to two distinct points. Almost all eyes have some degree of astigmatism. If the amount of astigmatism is great enough, then a person will experience blurred or distorted vision as depicted in the image on the right. The majority of astigmatism results from a cornea that has different curvatures. Astigmatism occurs in nearly everybody to some degree. For significant astigmatism, treatment is required, either with glasses, contact lenses, or sometimes implants. For further information, please visit the abstracts linked below:
