Treat Both Cataracts and Astigmatism with an AcrySof® IQ Toric Lens
Astigmatism is a common visual impairment caused by an irregularly shaped cornea or lens. Astigmatism is generally detected and treated in younger patients, but your vision can become further blurred by a clumping of proteins in the eye, an age-related condition known as a cataract. Cataract patients with astigmatism can now have both conditions treated in a single procedure. The advanced AcrySof® IQ Toric Lens is available at our Toronto clinic, where we use the latest surgical technology to restore our patients' clear vision. This premium intraocular lens (IOL) has an aspheric design that corrects astigmatism, reducing or even eliminating your dependence on glasses. TLC Laser Eye Center provides compassionate, quality care, which is why so many patients choose us to improve their eyesight. Schedule an appointment to see if a toric IOL is right for you.
Advances in Optics
Cataract surgery involves the replacement of the eye's natural, clouded lens with an artificial lens. Traditionally, standard IOLs addressed only the blurred vision that resulted from the cataract. If a patient also suffered from astigmatism, the surgeon would usually perform LASIK or limbal relaxing incisions (small incisions in the cornea) after the insertion of the IOL. With advancements in the optics of IOLs, a premium lens, like AcrySof® IQ Toric IOL, can provide cataract treatment and astigmatism correction in a single procedure.
Benefits of Toric IOLs
Refractive surgery and limbal relaxing incisions can only treat astigmatism related to the shape of the cornea. Some patients, however, suffer from lenticular astigmatism, a rarer type of astigmatism which is due to an irregularity in the natural lens. A patient can also have both types of astigmatism. Treatment with the AcrySof® IQ Toric Lens not only negates the need for another procedure, it can also address lenticular astigmatism. Surgeons who prefer using a toric IOL over limbal relaxing incisions also cite greater predictability of function and stability.
Results from a clinical trial indicate that toric lenses provide exceptional rotational stability while improving visual results. This type of IOL also sharpens distance vision by minimizing imprecise light focusing, also known as spherical aberration. Different models also can filter potentially damaging ultraviolet (UV) or blue light.
Find Out Whether a Toric IOL Is Right for You
If you are an adult cataract patient with pre-existing astigmatism who would like to improve uncorrected distance vision, you are likely a candidate for a toric lens. This advanced IOL has the greatest correction range available, so more patients can achieve crisp, clear distance vision and reduce their dependence on glasses.
Patients should note that the AcrySof® IQ Toric Lens does not correct presbyopia, the age-related diminished ability to focus on near objects. For this reason, you may still need reading glasses or bifocals for near-vision tasks, like reading, and some intermediate vision tasks, like working on a computer.
To determine if the AcrySof® IQ Toric Lens is right for you, one of our doctors will perform a thorough exam and review your medical history. Patients with chronic infections, uncontrolled diabetes, or other health problems may be advised to wait until these conditions are addressed before pursuing surgery.
