Many patients are surprised to learn that cataract surgery can do more than just remove a clouded lens. If you have astigmatism, your surgeon can address it during the same procedure.
The approach your cataract surgeon recommends depends on the degree of your astigmatism and what you want from your vision afterward. Understanding those options before your consultation can help you ask better questions and feel more confident about the decisions ahead.
Keep reading to learn how each approach works, who tends to benefit from it, and what to consider when discussing your choices with your cataract surgeon.
Why Astigmatism Matters When Planning Cataract Surgery
Astigmatism occurs when the cornea is shaped more like a football than a sphere. Instead of bending light to a single point on the retina, an irregularly curved cornea spreads light across two focal points, leading to blurry or distorted vision at multiple distances. It’s a common condition, and many people who develop cataracts also have some degree of astigmatism.
A standard monofocal lens implant, the baseline option in cataract surgery, replaces the clouded natural lens and restores vision clarity lost to cataract development. However, it does not correct astigmatism.
Patients who choose a standard lens and have uncorrected astigmatism will still need glasses full-time after surgery. Addressing astigmatism correction during cataract surgery, rather than relying on glasses afterward, is why so many patients explore premium options.
Here is a breakdown of each option available at Traverse City Eye:
1. Monofocal IOL with Limbal Relaxing Incisions
Limbal relaxing incisions, or LRIs, are tiny arc-shaped cuts made in the outer edge of the cornea at its steepest curvature. These incisions gently relax the cornea, making it more spherical and reducing astigmatism. The procedure is performed during cataract surgery and adds very little to overall recovery time.
LRIs are best suited for patients with low to mild astigmatism. They are the most budget-friendly option among those not covered by standard insurance, making them accessible to patients seeking some level of astigmatism correction without a high out-of-pocket cost.
One important limitation is that LRIs aim to reduce astigmatism rather than eliminate it entirely, so some residual astigmatism may remain. Patients should expect that glasses may still be needed for some tasks.
2. Toric Monofocal IOL
A toric lens implant has astigmatism correction built directly into the lens itself. Unlike LRIs, which reshape the cornea, a toric IOL compensates for the cornea’s irregular curve by bending light in a way that neutralizes the astigmatism before it reaches the retina. The lens is precisely aligned during surgery to match the orientation of the astigmatism.
Toric monofocal IOLs are particularly effective for patients with moderate to high astigmatism or for those whose corneal shape makes LRIs less predictable. Like any monofocal lens, a toric monofocal will deliver excellent vision at one primary distance (usually distance). Most patients will still need reading glasses or bifocals for near and intermediate tasks.
3. Toric PanOptix Trifocal IOL
The PanOptix trifocal lens goes a step further by combining toric astigmatism correction with multifocal technology. The trifocal design creates three distinct focal points: far away, intermediate (such as a computer screen), and up close for reading. Patients who choose this lens are typically aiming to minimize their dependence on glasses at all distances, not just at distance.
The toric version of the PanOptix addresses astigmatism while providing the full range of focus offered by the trifocal design. This lens is a strong option for active patients seeking the greatest possible visual independence after cataract surgery. Some patients notice mild glare or halos around lights during an adjustment period after surgery, though these effects typically diminish over time.
4. Toric Vivity Extended Depth of Focus IOL
The Vivity lens takes a different approach from the PanOptix. Rather than creating distinct focal points, the Vivity uses a proprietary X-Wave technology to stretch and shift the incoming light, producing a continuous range of clear vision from distance through intermediate. The result is a smoother visual experience with fewer halos and glare that some patients associate with multifocal lenses.
The toric version of the Vivity corrects astigmatism while delivering this extended depth of focus. It tends to appeal to patients who want to significantly reduce their reliance on glasses for everyday activities but are sensitive to visual disturbances or have been counseled that a multifocal lens may not be the ideal fit for them. Reading fine print may still require glasses in some cases.
5. Toric Light Adjustable Lens
The Light Adjustable Lens (LAL) is one of the most personalized options available. After your cataract surgery and initial healing period, your surgeon uses a series of brief, in-office UV light treatments to reshape the lens material inside your eye, fine-tuning your prescription to achieve your desired vision outcome. Before the prescription is permanently locked in, you can preview different vision settings.
The toric version of the LAL corrects astigmatism as part of that customizable process. This option is particularly appealing for patients who want a high level of precision and the ability to adjust their outcome if their vision does not feel exactly right during recovery. The trade-off is that you will need to return for multiple light treatment appointments and wear UV-protective glasses between sessions until the lens is finalized.
How Your Cataract Surgeon Helps You Choose
There is no single best option for every patient. Your cataract surgeon will evaluate several factors before making a recommendation, including the degree and type of your astigmatism, the shape and health of your cornea, your age, and whether you have had any previous eye surgeries. Your lifestyle and how much you want to rely on glasses after surgery also play a significant role in the conversation.
A thorough pre-surgical evaluation at Traverse City Eye will give your cataract surgeon the measurements needed to identify which options are most likely to deliver the results you are hoping for. Patients with irregular corneas, for example, may not be candidates for every type of toric lens, and the degree of astigmatism often naturally narrows the field of appropriate choices.
