For patients that have cataracts as well as astigmatism, “toric” premium lens implants options are available to help minimize or even eliminate your dependence on eye glasses after cataract surgery.
Until recently, patients that were cataract surgery candidates and had astigmatism, had no option that would correct the astigmatism aspect of their visual condition during cataract surgery. Surgeons would typically perform refractive surgery or LASIK after the insertion of a lens to correct the complete visual picture. With advancements in the optics of these lenses, the manufacturers have now been able to accommodate for astigmatism.
Many patients suffer from this common eye condition known as astigmatism. Often this astigmatism can lead to blurred or impaired vision if it becomes moderate or severe. The cause of the blurred and impaired vision is the result of the eye’s cornea or lens having an irregular shape. A normal eye’s cornea and lens have a spherical shape whereas an eye with astigmatism has a longer more oval shape.
Toric intraocular lenses (IOLs) correct for both conditions, cataracts and astigmatism. These toric IOLs also come in a wide variety of shapes, sizes, and models. Many of these models also have multifocal components to also decrease one’s need for reading glasses as well.
Clinical Study Data for the Acrysof IQ Toric® IOL:
- 94% of patients achieved uncorrected distance of 20/40 or better
- Improved contrast sensitivity in low-light situations
- Significant reduction in both spherical and total high order abberations
- Improved functional vision in challenging environments such as night driving, glare and fog
