Toric Lens Implants for Astigmatism Correction
Toric lens implants are a popular treatment option for patients with astigmatism and can help improve distance vision without eyeglasses. Astigmatism is very common after cataract surgery and almost one in three people experience blurred vision without eyeglasses or contact lenses. Toric intraocular lenses (IOLs) have diverse powers in different meridians of the lens that correct the asymmetric power of the eye that is a characteristic of astigmatism.
Cataract surgery with a Toric IOL is the same as conventional IOL, except that Toric IOLs have special markers on the peripheral parts of the lens. The markers enable the surgeon to see the orientation of the astigmatism correction in the lens and rotate it for proper alignment. Measurements are taken before surgery that enable the surgeon to choose the most beneficial power and the correct orientation to successfully correct astigmatism.
The toric lens may not correct all a patient’s astigmatism, especially if it is severe. Weaker eyeglasses can correct whatever astigmatism remains. Like the conventional lens implant, the toric lens is still a “single focus” lens and therefore reading glasses must still be used if the distance eyesight is good.
Benefits of Toric Lens Implants
Toric lens implants allow suitable patients to see better whenever they are not wearing eyeglasses, and any eyeglasses worn will not need to be as strong as before the surgery. For example, over-the-counter reading glasses or non-prescription sunglasses should work much better if your astigmatism is minimized.
Compared to the conventional lens implant, the toric lens does improve the “depth of focus” for patients with astigmatism. Astigmatism won’t go away on its own, although it can increase slightly in some eyes with age. The surgical recovery time is no different than traditional cataract procedures, and the benefit of the toric lens implant should last a lifetime.
