Intraocular lenses (IOLs) replace the eye’s natural lens during cataract surgery or Custom Lens Replacement *(refractive lens exchange- removing the lens of the eye and replacing it with a more multi-functional lens) to restore clarity and improve focus at multiple distances. Today’s IOL technology allows patients to reduce or even eliminate their need for glasses, offering sharper vision and a fuller range of focus than ever before. After careful examination and advance technology measurements, Dr. Rowen customizes the lens choice for each individual patients.
Dr. Sheri Rowen, MD, performs cataract and lens implant procedures at NVISION Eye Centers and sees patients in Newport Beach and Fullerton, CA. Recognized nationally for her work in ophthalmology and refractive surgery, she remains at the forefront of new implant technology. Patients throughout Orange County, trust her for precise compassionate care and excellent outcomes.
She has found that customizing lens replacements for each patient reults in the highest patient satisfaction as one lens does not fil all patients.
Advanced Lens Implant Options
Dr. Rowen offers the most current generation of premium intraocular lenses designed to provide clear vision at near, intermediate, and far distances. Each lens option is selected based on the patient’s unique vision needs and lifestyle goals.
ENVY IOL
The ENVY intraocular lens delivers a smooth transition of focus across multiple distances. Its design minimizes glare and halos while maintaining sharp vision for reading, computer work, and distance activities. It’s ideal for patients who want consistent clarity throughout the day without frequent dependence on corrective eyewear.
PanOptix® Pro
The PanOptix® Pro IOL is an FDA-approved trifocal lens engineered to improve vision at all ranges. It enhances brightness and contrast sensitivity in both high- and low-light conditions. Many patients find that PanOptix® Pro offers a very natural range of sight, making it one of the most popular options for post-cataract visual freedom.
Light Adjustable Lens (LAL)
The Light Adjustable Lens represents a breakthrough in customization. After cataract surgery, the lens can be adjusted in-office using precise light treatments to fine-tune vision according to the patient’s preferences. This ability to modify the lens after implantation ensures optimal clarity tailored to each individual eye.
Toric IOLs
Toric lenses are designed for people who have astigmatism, a condition that features uneven arc or curvature in their lens or cornea and causes blurry vision at all distances. A toric IOL has a special shape that compensates for this unevenness, effectively correcting the blurriness it causes. Toric lenses can be monofocal, multifocal or accommodating.
While toric IOLs can provide excellent distance vision, they may not be the best choice for patients who:
- Require very sharp near vision without glasses. Have significant dry eye or blepharitis that is not well-controlled.
- Have unstable corneas or irregular Astigmatism.
- In these cases, a different IOL option may be preferable. Your surgeon will help determine if you are a good candidate for a toric IOL based on your individual eye health, visual needs, and lifestyle. You should also consider your budget, as toric lenses are not covered by insurance.
PureSee IOL
The TECNIS PureSee IOL is a purely refractive extended depth of focus (EDOF) intraocular lens by Johnson & Johnson approved by the FDA on March 12, 2026. It provides clear distance and intermediate vision with functional near vision, avoiding diffractive rings to minimize halos, glare, and contrast loss.
VIVITY IOL
The Alcon Vivity IOL is a popular non-diffractive extended depth of focus (EDOF) intraocular lens that uses proprietary X-WAVE wavefront-shaping technology to deliver continuous distance and intermediate vision without relying on diffractive rings. Available on the Alcon Clareon platform, it stretches and shifts light waves rather than splitting them. This design provides a smooth focal range with a low-glare profile similar to a standard monofocal lens.
What to Expect During Surgery
IOL implantation is performed during cataract surgery, one of the safest and most common medical procedures worldwide. Using laser-assisted and micro-incision techniques, Dr. Rowen removes the cloudy natural lens and replaces it with a clear artificial one.
Surgery is typically completed in less than 20 minutes under local anesthesia, and most patients notice improved vision within a day. Minor adjustments in focus stabilize over the following weeks as the eyes heal.
Ideal Candidates for Premium IOLs
Advanced intraocular lenses may be recommended for patients who:
- Have cataracts that interfere with daily activities
- Wish to decrease dependence on glasses or bifocals
- Have healthy eyes and good overall eye structure
- Lead active lifestyles that require both near and distance vision
For those without cataracts, refractive lens exchange (Custom Lens Replacement- CLR procedure) may also be an option using the same lens technology.
