Toric lens implants are a valuable option for patients with significant astigmatism undergoing cataract surgery. While more expensive than standard IOLs, they offer precise correction of astigmatism, improved visual acuity, and reduced dependence on glasses or contact lenses.
The right lenses for you will depend on your vision needs, personal preferences and budget. It’s always best to discuss your options and needs with a specialized surgeon to find the right match.
What Are Toric IOLs?
Toric intraocular lenses (IOLs) are specialized intraocular lenses designed to correct astigmatism during cataract surgery or refractive lens exchange surgery.
If you have astigmatism, the curve of your eye is slightly imperfect. Rays of light entering your eye aren’t focused in one spot on the back of the retina. Instead, they’re spread out and don’t quite hit the retina in the right spot. Blurry vision results.
During cataract surgery, doctors don’t change the front of your eye to correct astigmatism. Instead, they implant a toric lens, which has a unique shape that compensates for the irregular curvature of the cornea. The result is crisp, sharp vision.
What is the cost of toric lenses for cataract surgery?
As with many other things in the vision care world, the cost of IOLs depends on where you live, your surgeon, and your insurance plan. You can generally expect to pay between $2,500 and $4,000 per eye considering also the cost of the lens.
How Do Toric Lens Implants Work?
Toric IOLs are technical tools made for talented ophthalmic surgeons. If your doctor thinks you need a toric IOL, they will measure your eye and design the lens accordingly. Here’s how the process works:
Measurement and Calculation
Before surgery, the eye surgeon takes precise measurements of your eye to determine the correct power and orientation of the toric lens implant needed to correct the astigmatism.
Toric Lens Design
Toric lenses are shaped like a rugby ball, with different powers in different meridians to compensate for the irregular curvature of the cornea characteristic of astigmatism. Doctors must understand your astigmatic axis and place the lens precisely along that meridian, often leveraging special tools to determine that axis. Toric lenses come with markers on the peripheral parts of the lens, allowing your doctor to see the ideal correction and rotate the lens accordingly.
Implantation
During surgery, the surgeon positions the toric lens implant in a specific orientation to neutralize the astigmatism from the cornea.
Correction
The toric lens implant refracts light evenly onto the retina, resulting in sharper vision and reduced dependence on glasses after surgery.
Long-Term Results
Toric lens implants are designed to be a permanent solution for astigmatism correction, ensuring long-term vision improvement
Available Toric Lens Options
Toric IOLs come in several types and models. While the toric feature corrects for astigmatism only, it can be combined with different lens options, both basic and premium.
Monofocal Toric Lens
Basic monofocal lenses provide good vision correction at one fixed focal point after cataract surgery, which can be set to near or distance vision. While simple monofocal lenses are typically covered by insurance, toric monofocal lenses are not. However, they are a more affordable option than premium toric lenses.
Multifocal Toric Lens
Multifocal lenses provide clear vision at multiple focal points. The more advanced models have three focal points at near, intermediate and distance. In the US, the only available IOL with this feature is the PanOptix Trifocal IOL, which has a toric version.
EDOF Toric Lens
Extended Depth of Focus (EDOF) IOLs also provide a wide range of clear vision that ranges from near to distance. However, they use different light manipulation technology to stretch the focus across these distances instead of creating multiple focal points. EDOF IOLs models typically offer a toric alternative.
Accommodating Toric Lens
Accommodating IOLs are a type of premium lens that also provides a wide range of vision, but they have a unique mechanism that replicates the way that the eye focuses on objects. This makes for a more natural vision experience. There are only two accommodating IOL models, the CrystaLens, and its toric version, the Trulign Toric.
What Are the Advantages of Toric IOLs?
If you’ve grabbed glasses for decades to do everyday things like make a grocery list or read the morning paper, toric IOLs could be right for you. Studies show that people with astigmatism can see better with toric IOLs after surgery than can people with traditional monofocal IOLs. Toric IOLs offer several advantages, including:
- Precise astigmatism correction: Corrects irregular corneal curvature.
- Improved visual acuity: Enhances sharpness and clarity of vision.
- Reduced dependence on glasses: Reduces need for glasses or contact lenses.
- Customizable: Available in various powers and sizes for individual needs.
These benefits make toric IOLs a valuable option for patients with astigmatism undergoing cataract surgery or refractive lens exchange surgery.
What Are the Disadvantages of Toric IOLs?
Toric IOLs provide several advantages, but there are some factors you should keep in mind before going ahead with the surgery:
- Additional Cost: Toric IOLs are considered premium lenses, so they are not covered by regular insurance.
- Single-Focus Lens: Like monofocal IOLs, toric IOLs are single-focus lenses and do not provide perfect vision at all distances. Reading glasses may still be necessary.
- Limited Customization: While toric IOLs are customizable, they are not as versatile as some other types of IOLs, such as multifocal or accommodating lenses.

Toric IOL Side Effects
The side effects of toric intraocular lenses (IOLs) are generally rare and manageable. Reported side effects include:
- Astigmatism Overcorrection or Undercorrection: The toric IOL may not fully correct the astigmatism, resulting in some residual astigmatism.
- Dislocation or Rotation of the IOL: In about 3 percent of cases, people need a lens adjustment, because the Toric IOL must be precisely placed in order to properly correct vision.
- Glare and Halos: Some patients may experience glare, halos, or starbursts around lights, especially at night.
These side effects are generally rare and can be managed with proper surgical technique and patient selection.
When is a toric IOL not recommended?
While you might want a toric IOL, your doctor might not recommend them in certain cases. Eyes with severe astigmatism caused by a condition like keratoconus might not be right for these types of lenses.
Does Medicare Approve Toric IOLs?
Original Medicare plans cover traditional lenses and the surgeries needed to implant them. If you choose a toric IOL, your traditional Medicare plan won’t cover the cost of the lens or the surgery.
If you want to use toric IOLs and you’re using traditional Medicare, tell your doctor before the procedure starts. You’ll need to work out payment plans.
Some people use Medicare Advantage plans, purchased through a health insurance company, to get better health care coverage. These plans could cover toric IOLs and their surgeries, but you’ll need to read the fine print to be sure.
Toric IOL Frequently Asked Questions
What is the success rate of toric IOL?
Researchers say toric IOL success rates range between 70 percent and 80 percent. Newer surgical methods, including those that involve lasers, could make that success rate even higher.
Is a toric lens worth the cost?
It depends. If you’d like to reduce your dependence on glasses, paying a little more for these lenses could be appropriate for you. If your budget is tight and your glasses are covered by insurance, getting a standard lens might seem like the right choice.
How long does it take to adjust to this type of lens?
Experts say it can take up to six months to get used to your new lenses. If you’re struggling to see clearly, talk with your doctor and ensure your eyes are healing properly.
How long does a toric lens last?
Your new cataract lens will last a lifetime, and you don’t need to do anything to maintain it.
Can I get a Toric Lens if I don’t have cataracts?
If you have astigmatism but no cataracts, you can still benefit from a Toric IOL by having a Refractive Lens Exchange Surgery (RLE). The procedure is very similar to cataract surgery. It only takes about 15 minutes per eye, and general anesthesia is not required.
