Your Guide to Picking the Best Toric Lens
Think of a 65-year-old patient. They have cataracts and astigmatism. Daily tasks like driving or reading are hard. After a precise toric IOL surgery, they see clearly far away without glasses. That is the power of a smart lens choice. Since up to 40% of cataract patients have astigmatism, you need to get it right.
This guide shares top tips for toric IOL selection. It uses the latest 2024-2025 research. You will learn how to check patients, pick the best lens, and improve surgical results. By the end, you will have clear steps to boost your practice and change patient lives.
What Are Toric IOLs?
Toric IOLs are special lenses made to fix astigmatism during cataract surgery. A standard lens only fixes one type of blur. A toric lens has different powers across its surface to fix the irregular shape of the cornea. This is a game-changer for patients who want to ditch their glasses.
Studies from 2024-2025 show toric IOLs work very well. They fix astigmatism in over 85% of cases. One study of 121 eyes found the lenses only rotated about 2 degrees on average after surgery. This shows they are stable. You can get them as monofocal, multifocal, or EDOF types. This lets you match the lens to the patient’s needs.
Why focus on good selection? A poor choice can leave astigmatism behind. This can mean vision is no better than 20/40. By choosing well, you can often leave less than 0.5 diopters of astigmatism. This greatly improves a patient’s life.
Why Choose a Toric IOL?
- Great Astigmatism Fix: Corrects from 0.75 to 4.75 diopters on the cornea. This is much better than glasses after surgery.
- Better Vision: Recent data shows 83.5% of patients get over 75% efficacy. They see better at a distance without glasses.
- Freedom from Glasses: Up to 88.9% of patients with lenses in both eyes need no glasses for far and mid-range vision.
- Stays in Place: The average lens rotation is under 3 degrees after three months. This means few need to be moved back.
But, not everyone is a good fit. Patients with irregular astigmatism, like from keratoconus, should not get them. This is why a good pre-op check is key.
Who Is a Good Candidate for a Toric IOL?
Good selection starts with the right patient. Look for patients with regular corneal astigmatism of at least 1.0 diopter. Fixing less than this may not be worth the extra step. New guidelines say toric IOLs are a strong choice for over 2.0 diopters. But even 0.75 can help a motivated person.
Talk about patient goals early. Those who want to see well for golf or night driving are great fits. If they liked monovision before, it can guide your target.
Who Should Avoid Them?
- Irregular Corneas: Issues like basement membrane dystrophy make results hard to predict.
- Other Eye Problems: Severe dry eye or weak zonules can raise the risk of the lens moving.
- Very High Hopes: Tell patients about possible halos or glare with multifocal types. But, 61.1% report none in new studies.
- Very Short or Long Eyes: Short eyes (under 23 mm) have a higher chance of the lens rotating.
A 2025 study on high hyperopes showed that careful choice leads to the best results.
The Pre-Op Check: Your Blueprint for Success
Good measurements are a must. Use modern tools like optical biometers. Get both the front and back of the cornea for a full picture. Take the readings more than once to be sure. If they differ by over 0.25 diopters, look into it.
Use a good calculator like the Barrett Toric Calculator. It uses anterior chamber depth and the back cornea. New insights show this cuts down on errors, especially in long eyes.
Key Pre-Op Steps
- Map the Cornea: Make sure the astigmatism is regular and rule out other issues.
- Take Multiple Measurements: Average two consistent readings from your biometer.
- Use the Refraction: Blend the manifest refraction with the corneal map for axis alignment.
- Talk to the Patient: Set clear goals. Plan for age-related shifts in astigmatism.
New data shows with-the-rule (WTR) astigmatism has lower efficacy (69.6% vs. 86.7%). This guides under-correction plans.
How to Choose the Right Toric IOL Model
Many models exist in 2026. Picking one means matching it to the patient. Monofocal torics like AcrySof IQ are very stable. Multifocal torics, like AT LISA toric, help patients who need to see up close. EDOF options like the new RayOne EMV Toric offer great contrast with astigmatism correction.
What Guides Your Choice?
- Cylinder Power: Start at 1.5 diopters. Some lenses offer 1.0 for fine tuning.
- Lens Design: Plate-haptic designs are very stable in long eyes.
- Lens Material: Hydrophobic acrylic lenses rotate less.
- Patient Vision Needs: Trifocal torics give full-range vision. 94.4% of patients are happy with them.
A 2025 study found similar visual results between major brands, but AcrySof was more stable in long eyes.
Planning the Surgery for Precision
Good planning is everything. Mark the eye while the patient is sitting up to avoid errors. Use a toric bubble marker. Account for the small astigmatism your incision causes (0.2-0.25 diopters).
For high astigmatism, you can pair a toric IOL with limbal relaxing incisions (LRIs). A femtosecond laser can make these LRIs very precise.
Your Pre-Surgery List
- Mark the Axis: Do it by hand or with an image-guided system.
- Pick the Lens Power: Use three-quarter steps. Undercorrect WTR, overcorrect ATR.
- Use Intraoperative Tools: Devices like ORA can confirm your readings during surgery.
- Prepare the Capsule: Make sure the capsulorhexis fully overlaps the lens for stability.
2025 studies show correction indices near 0.93, meaning a slight under-correction but stable outcomes.
Surgery Tips for Perfect Placement
During surgery, put the lens in a tiny bit under-rotated. This makes it easy to adjust clockwise. Remove the viscoelastic from behind the lens first to stop it from shifting. In myopic eyes with a large bag, a capsular tension ring can help.
Use small openings to check the position. Avoid big ink marks that can fade. Use a Sinskey hook for fine adjustments.
Key Surgery Tips
- Check the Alignment: Compare your marks to the lens axis. Rotate it before the final set.
- Manage Viscoelastic: Clear it from under the lens to avoid pressure changes.
- Keep Incisions Small: Under 2.5 mm causes less astigmatism.
- Use Aberrometry: This can cut residual errors to under 0.5 diopters in 75% of cases.
New data confirms these methods keep rotation low.
After Surgery: Care and Checks
Wait about a month for the swelling to go down before a full check. Look for lens rotation, macular edema, or dry eye. If more than 0.75 diopters of astigmatism remains, think about moving the lens or a laser touch-up like PRK.
Patient surveys from 2025 show high satisfaction scores. Most patients see no halos. Plan follow-ups for one week, one month, and three months.
After-Surgery Plan
- Check for Rotation: The average is 2 degrees at three months. Reposition if it’s over 5 degrees.
- Monitor Refraction: The cylinder often drops to -0.31 diopters on average.
- Check Vision: Address any glare with eye drops.
- Enhancement Options: PRK works for residuals. Avoid LASIK in older patients.
Studies show 94.4% would pick the same IOL again.
Real Stories and Data from 2024-2025
Recent data tells a good story. One study used multifocal torics in long eyes. It cut refractive cylinder from -1.88 to -0.31 diopters. Over 91% of lenses rotated less than 5 degrees. Another study compared three models and found similar vision but better stability with certain designs.
In high hyperopes, under-correction led to stable outcomes. These cases show that good toric IOL selection leads to 85.1% efficacy and happy patients.
Case Snapshots
- ATR Astigmatism Patient: Over-correction left only 0.26 diopters. The patient saw far away without glasses.
- Both Eyes with Multifocal: 66.7% were free of reading glasses.
- Long Eye Case: A plate-haptic design kept rotation to just 2.25 degrees.
These stories show the value of evidence-based choices.
What’s Next for Toric IOLs in 2026?
The future looks bright. 2026 will bring better EDOF torics with improved contrast. New lenses approved in 2025, with monofocal-like performance, will add more options. AI in calculators may make predictions even better, cutting rotation risks.
Expect more stable hydrophobic materials and custom powers for perfect correction. Staying up-to-date on these trends means you give your patients the best care.
