Options that allow you to meet your personalized vision goals

EMPOWER YOUR VISION

CATARACT SURGERY

At our practice, we understand that choosing cataract surgery—and the right lens implant for you—is a deeply personal decision. With today’s many advanced options (including standard monofocal lenses, astigmatism-correcting toric lenses, multifocal or extended depth-of-focus lenses, and the customizable Light Adjustable Lens), the path forward can feel complex. That’s why we take the time to listen carefully, explain clearly, and guide you through each choice with thoughtfulness and expertise. Together, we’ll identify the solution that aligns with your individual lifestyle, visual needs, and long-term goals.

CATARACT SURGERY

What is a cataract, and how will I know that it is ready for surgery?

A cataract is a clouding of the eye’s natural lens that can cause blurry vision, glare, difficulty reading, and trouble seeing clearly at night. Cataracts develop gradually, and early changes may not require treatment. Surgery is typically recommended when the cataract begins to interfere with your daily activities—like driving, reading, or recognizing faces—and when clearer vision would meaningfully improve your quality of life. Surgery entails breaking up and removing the cataract from the eye, through microscopic incisions, and placing a new artificial lens implant in the eye. The decision to proceed with surgery is personal, and we’re here to help you make that choice with clarity and confidence.

What is the process to get surgery done by Dr. Nuyen and Dr. Sacks?

Once you and your doctor decide to move forward with cataract surgery, we’ll schedule a dedicated preoperative appointment where you’ll receive detailed information about the procedure, what to expect, and how to prepare. We do surgery one eye at a time, so if you are receiving surgery for both eyes, the second eye surgery will usually be scheduled two weeks after the first. Surgery is performed at La Peer Surgery Center, a nearby outpatient facility known for its excellent care for our patients. You will receive light intravenous sedation, so that you will feel calm, relaxed, and pain-free. The duration of surgery is usually 15 minutes.

After surgery, we’ll see you for two post-operative visits—one the day after and another about five days later—to monitor your healing and ensure you're on track. During this time, we’ll review light activity restrictions and guide you through your prescribed eye drop regimen, which typically lasts about three weeks. Most patients experience significant improvement in their vision within the first week.

What are my choices for my new lens implant?

There are several lens implant options available to match your visual goals after cataract surgery. We will help you weigh these options carefully to find the one that fits your lifestyle and visual priorities.

Standard Monofocal lens implant

Toric Monofocal Lens implant

Extended depth of field (EDOF) Lens implant

Multifocal Lens implant

Light Adjustable Lens (LAL)

The standard monofocal lens implant, also known as a single-focus intraocular lens (IOL), is the most commonly used lens in cataract surgery. It is designed to provide clear vision at one fixed distance—either far, intermediate, or near. Most patients choose to have it set for distance vision, allowing them to see things like street signs or TV clearly without glasses, while still needing glasses for near tasks like reading or using a phone. Alternatively, some may choose a near-focus target if that better suits their lifestyle.

Monofocal lenses offer excellent image clarity and have the lowest risk of visual side effects, such as glare or halos, which makes them a highly reliable and well-tolerated option. If you have astigmatism and choose a standard monofocal lens (not the toric version), glasses may still be needed to fully correct your vision. This lens is often the best choice for patients who prefer simplicity, prioritize optical quality, or are not candidates for more advanced lens types.

The standard monofocal lens implant offers clear vision at a single focus—typically set for either distance or near—often requiring glasses for the opposite range.

Standard Monofocal Lens Implant

The standard toric lens implant is a type of monofocal intraocular lens (IOL) specifically designed to correct astigmatism—a common condition where the cornea has an irregular shape, causing blurred or distorted vision. Like the standard monofocal lens, the toric lens provides clear vision at a single focal distance (typically set for distance), but with the added benefit of reducing or eliminating astigmatism, which standard lenses do not correct.

By precisely matching the lens to your individual corneal shape and aligning it during surgery, the toric IOL can significantly sharpen vision and reduce the need for glasses for distance tasks. However, you may still need glasses for near activities such as reading or computer work, depending on your chosen focus. Toric lenses are a great option for patients with moderate to high corneal astigmatism who want greater clarity and visual independence after cataract surgery. Proper preoperative measurements and meticulous surgical planning are key to achieving optimal results.

A toric monofocal lens implant corrects astigmatism in addition to providing single-distance focus, offering sharper vision for those with significant corneal astigmatism.

Toric Monofocal Lens Implant

The Extended Depth of Focus (EDOF) lens implant is an advanced intraocular lens (IOL) designed to provide a continuous range of clear vision, primarily from distance to intermediate, with some functional near vision. Unlike multifocal lenses that split light into multiple focal points, the EDOF lens elongates the focus, creating a smoother transition between ranges and often reducing issues like glare, halos, or contrast sensitivity loss.

This lens is ideal for patients who prioritize sharp distance and intermediate vision—such as for driving, computer use, and seeing faces—while still desiring some reduced dependence on reading glasses. Although many patients can perform occasional near tasks unaided, most will still need reading glasses for prolonged or fine print reading.

The EDOF lens offers a balanced option for those wanting more visual range than a monofocal lens but with fewer visual side effects than traditional multifocals. It’s best suited for individuals with healthy eyes who value crisp vision across a broad spectrum of daily activities. A toric (astigmatism-correcting) version of this lens implant is available as well.

The extended depth of field (EDOF) lens implant provides a continuous range of focus, primarily enhancing distance and intermediate vision with reduced dependence on glasses.

Extended Depth of Field (EDOF) Lens Implant

The multifocal lens implant is a premium intraocular lens (IOL) designed to provide vision at multiple distances—near, intermediate, and far—by distributing light to different focal points. This allows many patients to be less dependent on glasses for most daily activities, including reading, driving, using a computer, and seeing objects across a room.

While these lenses can offer a high level of visual independence, they do require the brain to adapt to the way light is split. As a result, some patients may experience halos, glare, or reduced contrast sensitivity, especially in low-light settings like night driving.

Multifocal lenses are best suited for patients who have healthy eyes, are motivated to reduce their need for glasses, and are comfortable with a period of visual adaptation. During your consultation, we’ll help you understand if this lens matches your visual goals and lifestyle. A toric (astigmatism-correcting) version of this lens implant is available as well.

The multifocal lens implant is designed to provide clear vision at near, intermediate, and distance ranges by splitting light to multiple focal points, though some patients may notice halos or glare, especially at night.

The Light Adjustable Lens (LAL) is a groundbreaking intraocular lens (IOL) that allows your vision to be customized after cataract surgery, offering the most precise level of personalization available today. Unlike standard lenses, the LAL is made from a special photosensitive material that can be non-invasively adjusted using targeted UV light treatments in the weeks following surgery.

Initially, the lens is implanted like any other IOL during cataract surgery. After your eye has healed, we perform a series of light treatments in our partner Vision Adjustment Center using a special device to fine-tune the lens power based on your real-world visual experience. Once the ideal vision is achieved—whether for distance, near, or a blended focus—we lock in the result permanently.

The LAL is particularly well-suited for patients who want a high degree of control over their final visual outcome or those who’ve had prior refractive surgery (like LASIK, PRK, or RK), where standard IOL calculations may be less predictable. For several weeks after surgery and until the final “lock-in” treatment, you’ll need to wear UV-protective glasses to preserve the lens’s adjustability. With thoughtful planning and patient cooperation, the Light Adjustable Lens offers exceptional clarity and flexibility in achieving personalized visual goals.

The Light Adjustable Lens (LAL) is a unique option that allows your vision to be fine-tuned after surgery using specialized light treatments, offering an exceptional level of personalization.
