An intraocular lens (IOL) is an implanted synthetic lens that replaces the eye’s natural lens. Depending on the type selected, an IOL may also correct nearsightedness or farsightedness, and a patient who has received an IOL can still have laser vision correction.
The intraocular lens (IOL) is a foldable lens that slides through a tube and unfolds in the capsular bag. Your cataract surgeon may center the new lens with the lens capsule if necessary. Once the lens is centered, the surgery is complete. In most cases, no stitches are required.
Modern-day lens implants for after cataract surgery have significantly improved over the last 10 to 20 years. Intraocular lenses come in a variety of materials and designs. Your cataract surgeon will advise you on the best lens to fit your vision and lifestyle.
Astigmatism is asymmetric steepening of the cornea or natural lens, which causes light to be focused unevenly. Astigmatism is a common refractive error making the eye(s) unable to see objects clearly from a distance or up close. Astigmatism may vary in each eye and can accompany nearsightedness or farsightedness. For individuals with uncorrected astigmatism, images may look blurry or shadowed.
At Thomas Eye Group, we’re pleased to offer Toric intraocular lenses (IOLs) for astigmatism correction after cataract surgery. With recent advancements in the optics of IOLs, patients who are IOL candidates and have astigmatism now have an IOL option to correct the astigmatism aspect of their visual condition. Toric IOL technology uses materials that have been successfully used in contact lenses and proven safe for the eye.
