Toric Intraocular Lenses for Astigmatism Correction at OC Eye Institute
If you have astigmatism and are undergoing cataract surgery or lens replacement, a toric intraocular lens (IOL) can correct your corneal irregularity at the same time — delivering sharper, clearer vision and reducing your need for eyeglasses after surgery. At OC Eye Institute in Laguna Hills and Santa Ana, CA, Dr. George Salib specializes in selecting and placing advanced toric IOLs tailored to each patient’s unique eye structure.

What Is a Toric IOL and How Does It Work?
A toric intraocular lens is a type of premium artificial lens designed specifically to correct astigmatism during cataract surgery or refractive lens exchange. To understand how it works, it helps to first understand astigmatism itself. Astigmatism occurs when the cornea — the clear front surface of the eye — is shaped more like a football than a basketball. Instead of being uniformly round, it is oblong or oval in one meridian, which causes light entering the eye to focus at two separate points rather than one. The result is blurred or distorted vision at all distances, not just near or far.
Standard intraocular lenses used in cataract surgery are spherical in shape, meaning they are symmetrical in all directions. While they correct the power of the natural lens, they cannot address the cylindrical correction needed to neutralize astigmatism. A toric IOL, by contrast, is designed with different powers in different meridians of the lens. When precisely aligned within the eye during surgery, the toric lens offsets the uneven curvature of the cornea and brings light to a single, clear focal point — dramatically improving visual clarity.
The success rate for toric IOLs is approximately 95%, and many patients report an immediate and striking improvement in their vision after surgery. The lens is inserted as an outpatient procedure: after numbing the eye with anesthetic drops, Dr. Salib removes the natural lens through a small corneal incision and positions the toric IOL with precision. Most patients notice sharper vision within 24 hours.
The Benefits of Toric IOLs at OC Eye Institute
Choosing a toric IOL as part of your cataract surgery or lens replacement procedure offers several significant advantages over a standard monofocal lens when astigmatism is present. Patients who select toric IOLs typically experience clearer distance vision without needing to rely on glasses or contacts for distance tasks. Many describe the visual improvement as transformative compared to the blurry, distorted images they experienced before surgery.
It is important to understand that the toric lens corrects one focal distance — it does not adjust from near to far as a healthy young eye does. This means some patients may still benefit from reading glasses for close-up tasks. For patients who want to address both astigmatism and the need for reading glasses, Dr. Salib may discuss a monovision arrangement — in which one eye is corrected for distance and the other for near — or a toric multifocal IOL, which combines astigmatism correction with multifocal technology.
As with any eye surgery, toric IOL implantation carries a small risk of complications. These occur in approximately 2% of cases and may include increased intraocular pressure, infection, bleeding, or posterior capsule opacification. Our team thoroughly discusses all risks and benefits with you prior to surgery so you can make a fully informed decision. If you are frustrated by your current eyeglasses or contact lenses and want to explore a lasting alternative, we invite you to schedule a consultation at OC Eye Institute in Laguna Hills and Santa Ana, CA.

Frequently Asked Questions About Toric IOLs
What is a toric IOL and who needs one?
A toric IOL is a premium intraocular lens designed to correct astigmatism during cataract surgery or refractive lens exchange. It is recommended for patients who have a measurable degree of corneal astigmatism that would otherwise remain uncorrected with a standard spherical IOL. Without a toric lens, residual astigmatism can lead to blurry vision even after successful cataract removal. Dr. Salib at OC Eye Institute in Laguna Hills and Santa Ana, CA will measure your corneal shape to determine whether a toric IOL is right for you.
How is astigmatism diagnosed before surgery?
Prior to surgery, our team performs a comprehensive pre-operative evaluation that includes precise measurements of the cornea’s curvature using corneal topography and other advanced diagnostic tools. These measurements allow Dr. Salib to quantify the degree and axis of your astigmatism, and to select and orient the toric IOL for maximum correction. Accurate pre-surgical measurements are essential to achieving the best possible visual outcome.
Will I still need glasses after getting a toric IOL?
A toric IOL is designed primarily for distance vision correction. While it significantly reduces or eliminates the need for distance glasses, you may still need reading glasses for near tasks such as reading fine print. Patients who want to reduce their dependence on glasses at all distances can discuss a toric multifocal IOL or a monovision approach during their consultation with Dr. Salib at OC Eye Institute.
How is the toric IOL positioned correctly in the eye?
Correct rotational alignment of the toric IOL within the eye is critical to achieving optimal astigmatism correction. Dr. Salib uses careful pre-operative markings and precise surgical technique to orient the lens at the correct axis during implantation. In rare cases where the lens shifts position during healing, a minor adjustment procedure may be performed. Advanced laser-guided technology, including options available with laser cataract surgery, further enhances alignment accuracy.
Is toric IOL surgery safe?
Toric IOL implantation is a safe procedure with a success rate of approximately 95%. As with any eye surgery, a small risk of complications exists — occurring in roughly 2% of cases — and may include infection, increased intraocular pressure, or posterior capsule opacification. Our team reviews all potential risks and benefits with every patient before proceeding. Call (949) 770-1322 - Laguna Hills Office or (949) 770-1322 - Santa Ana Office with any questions about the safety of toric lens surgery.
Is a toric IOL covered by insurance?
The cataract surgery procedure itself is typically covered by Medicare and most insurance plans. The toric IOL is considered a premium lens upgrade and involves an additional out-of-pocket cost not covered by standard insurance. At OC Eye Institute in Laguna Hills and Santa Ana, CA, we offer flexible payment options to help make premium lens choices more accessible. Visit our insurance page for more information.
