Toric IOLs for the Correction of Astigmatism
What Is an Astigmatism?
Astigmatism is an eye condition that affects more than 50% of the population. In fact, the vast majority of patients undergoing cataract surgery today have measurable levels of astigmatism. Corneal astigmatism is simply a condition that causes blurred or double vision due to the shape of the cornea, the outer ‘windshield’ part of the eye where light first passes through. In patients who do NOT have astigmatism, their cornea is regular and round as in the shape of a dome or hemisphere. In patients who HAVE astigmatism, their corneas are more oval-shaped like the back surface of a spoon or side of a football where there is a difference in the steepness in each direction. This irregular shape causes the light rays to not properly focus on the retina, or back portion of the eye. Because these light rays are skewed, people with astigmatism need prescription glasses or special contact lenses to correct this condition.
Treatments for Astigmatism in Cataract Patients
Toric intraocular lenses (IOLs) are now available that can correct for astigmatism. These toric lens implants are designed with a specific shape that counteracts the irregularity that causes the astigmatism in the first place. Thanks to their unique design, Toric IOLs are designed to refocus light rays as they pass through the lens and position them into focus on the retina. The result is correction of your astigmatism and reduced dependence on glasses or contact lenses.
Customized Treatment Plan to Match Your Lifestyle
Toric lens implants come in both a monofocal and multifocal/extended depth of focus option. Based upon the vision correction option you and your surgeon choose, your surgeon will customize a treatment plan for you to achieve the visual outcome you desire.
For patients who elect one of our astigmatism-correcting options prior to cataract surgery, you will undergo a full vision analysis at Berkeley Eye Center. Our doctors will then customize a treatment plan that may include a Toric IOL engineered to provide you with superior vision. Your surgical plan may also incorporate corneal relaxing incisions to treat your astigmatism. These procedures are designed with the goal to minimize or eliminate any astigmatism and give you the clearest vision without glasses or contacts.
With the monofocal toric lens, the vast majority of patients do not need to wear glasses for most normal activities requiring distance vision after this procedure, but you may need glasses for near tasks. A premium toric lens is also available to help treat the distance and near vision.
