Since the shape of your cornea often causes astigmatism, you need special contact lenses to correct your eye condition. Many optometrists recommend toric contact lenses for astigmatism since they move with your eye to correct distorted vision at every angle.
How do you know if you need toric lenses?
People with mild to moderate corneal astigmatism, low levels of other refractive errors, and generally good eye health are good candidates for toric lenses. Downsides include the lenses’ mobility in the eyes, which can make vision blurry or inconsistent. Toric lenses are also more expensive than regular contact lenses.
What level of astigmatism require toric lenses?
“For astigmatism treatment at the time of cataract surgery, use toric IOLs whenever you can—roughly speaking, for with-the-rule astigmatism greater than 1.5 D and against-the-rule greater than 0.4 D,” recommends Dr. Raviv.
Who should use toric lenses?
Toric lens implants are one of the most popular technologies for cataract patients with astigmatism who do not intend to wear eyeglasses at all times. They are designed to improve how well you see without eyeglasses in the distance, as compared to if you had a standard lens implant.
Do I need toric lenses for slight astigmatism?
You’ll need toric contact lenses that are specifically designed to correct astigmatism. They’ll also correct your nearsightedness or farsightedness. Toric contacts are thicker, larger, and more stable than non-toric contacts.
What is considered mild astigmatism?
Between . 75 and 2 diopters is considered mild astigmatism. Between 2 and 4 diopters is moderate astigmatism, and 4 or more diopters is considered significant or “bad” astigmatism. Generally, eyes with 1.5 diopters of astigmatism or more require correction.
What is the difference between astigmatism and toric?
Toric contact lenses can rectify astigmatism. The main difference between these and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism.
Is astigmatism 0.25 Bad?
If your number is between +0.25 and +2.00, you have mild farsightedness. If your number is between +2.25 and +5.00, you have moderate farsightedness. If your number is greater than +5.00, you have high farsightedness.
Can IOL correct astigmatism?
Corneal astigmatism can be corrected during cataract surgery by implanting a Toric Intraocular lens (IOL), corneal arcuate incisions, or a combination of both.
Why is my toric lens blurry?
Astigmatism is an imperfection in the curvature of the cornea or lens. Normally the lens or cornea are curved equally in all directions. In case the curvatures are not equal a Toric lens may be implanted during cataract surgery. In certain cases, this might lead to blurry vision after toric lens implant.
How long do toric lens implants last?
Unlike natural lenses, IOLs do not break down over a person’s lifetime and do not need to be replaced. It is possible to exchange implants if necessary.
How can you tell if you have astigmatism?
Astigmatism is diagnosed with an eye exam. A complete eye exam involves both a series of tests to check eye health and a refraction, which determines how the eyes bend light. Your eye doctor may use various instruments, aim bright lights directly at your eyes and ask you to look through several lenses.
What happens if you don’t correct astigmatism?
Astigmatism is caused by the shape of the eye’s cornea or lens, and glasses can’t change those. However, wearing glasses with an incorrect astigmatism prescription can cause other problems, including blurry vision, eye strain and headaches.
Can I get colored contacts with astigmatism?
If you’re interested in trying colored contacts, but you have astigmatism, you may be asking yourself, “Can you get colored contacts with astigmatism?” The short answer is, yes, you can get colored contacts for astigmatism, however there are not as many options for people with astigmatism.
Why are toric lenses so expensive?
It generally takes more expertise for an eye doctor to fit a patient for toric contacts than it does for regular lenses. For this reason, a toric lens fitting may cost more than a regular contact lens fitting. Since torics are more complex in design, the cost of replacing them will be higher than most regular contacts.
