At UltraVision, with offices in San Antonio and Eagle Pass, Texas, the goal is to improve your vision. If you’re having cataract surgery and also suffer from astigmatism, you may be a candidate for a toric intraocular lens (IOL) placement, which corrects both the cataract and astigmatism to improve your eyesight. For complete eye care, including specialty lenses for cataract surgery, call the office or schedule an appointment online.
Cataracts may occur naturally with age or due to an eye injury, and they cause your normally clear eye lens to become cloudy. Cataracts usually develop slowly, and if they affect your vision, they can typically be managed with glasses.
However, as your cataract worsens, it may significantly impair your vision, making tasks such as driving and reading more difficult. If your prescription eyeglasses are no longer improving your eyesight, your eye care specialist at UltraVision may recommend cataract surgery to improve your vision.
During cataract surgery, your eye surgeon replaces your cloudy lens with an artificial lens, also referred to as an intraocular lens (IOL).
A toric IOL is a specially designed soft artificial lens used to replace your cloudy lens that also allows your surgeon to precisely orient the lens to address astigmatism. The lens is made up of biocompatible material and has been used to correct vision in more than 25 million eyes since 1991.
Astigmatism occurs when the cornea of your eye is curved in such a way that it prevents light from focusing properly on the retina, leading to blurry vision. If you have astigmatism, your cornea may be shaped more like a football, with flatter and steeper curves than the preferred rounded shape.
Almost everyone has some degree of astigmatism. If your astigmatism is affecting your vision, however, it can be corrected with:
Your eye care specialist at UltraVision may suggest a toric IOL to correct both the cataract and astigmatism if you’re having cataract surgery. Without placement of the toric IOL, you may still need to wear glasses to correct the vision changes caused by your astigmatism following surgery.
Placement of your toric IOL for cataracts is done as an outpatient procedure. A local anesthetic is used to ease any discomfort before surgery begins. Then, under a microscope with precision and care, your eye surgeon makes a small incision into your lens, and with special microsurgical instruments, removes the cataract lens.
The toric IOL is then inserted into your eye and the incision is closed with dissolvable stitches.
