A New Standard in Personalized Vision Correction

Pacific Vision Institute has spent more than 25 years bringing the newest refractive technology to the Bay Area first, from IntraLASIK to CONTOURA^® Vision topography-guided treatment. WaveLight Plus ray-tracing LASIK in San Francisco continues that pattern, and Dr. Ella Faktorovich and Dr. Andres Parra personally review each patient's eyes to determine whether it's the right fit.

What Is Ray-Tracing-Guided LASIK?

Ray-tracing-guided LASIK is a method of planning LASIK surgery using an optical model that traces how individual light rays travel through each unique structure of a patient's eye, rather than relying on population-based averages. WaveLight Plus, developed by Alcon, is the platform that brought this approach to LASIK.

WaveLight Plus pairs its Sightmap diagnostic device with the EX500 excimer laser. According to Ophthalmology Times, the Sightmap gathers more than 100,000 data points using a combination of ocular wavefront, biometry, and corneal tomography measurements to build what Alcon calls a "Digital Eye Twin" — a three-dimensional model of the patient's eye. That model feeds directly into ray-tracing software, which calculates a customized ablation profile without requiring manifest refraction input, streamlining the planning process.

Builds a 3D model from wavefront, biometry, and corneal tomography data
Calculates the ablation profile through computerized ray tracing rather than population averages
Uses the EX500 excimer laser, the same laser platform behind CONTOURA^® topography-guided LASIK
Designed to address both standard refractive error and individual optical imperfections

Benefits of WaveLight Plus LASIK

WaveLight Plus ray-tracing LASIK in San Francisco is designed to go beyond standard correction of nearsightedness, farsightedness, and astigmatism. Because the ablation plan is generated directly from measured optical data, it can account for irregularities that a standard refraction alone might miss.

In a peer-reviewed comparison study published on PubMed, ray-tracing-guided LASIK using WaveLight Plus demonstrated high safety and efficacy, with visual acuity outcomes comparable to wavefront-optimized LASIK, and slightly higher accuracy in manifest refraction spherical equivalent, without needing a manifest refraction for treatment planning. For patients, that can translate into a faster, more objective path to a personalized prescription.

Am I a Candidate for WaveLight Plus LASIK in San Francisco?

Most adults being evaluated for LASIK are also reasonable candidates for WaveLight Plus, provided their corneas are healthy and their prescription has been stable for at least a year. You may be a particularly strong candidate for ray-tracing LASIK in San Francisco if:

You want your ablation profile based on measured eye data rather than manifest refraction alone.
You have mild to moderate irregularities the standard refraction doesn't fully capture.
You've been told you're a candidate for LASIK but want the most personalized planning technology available.
You're comparing WaveLight Plus with topography-guided CONTOURA^® LASIK and want guidance on which is better suited to your eyes.

A comprehensive evaluation, including corneal mapping and a Sightmap scan, is required to confirm candidacy. Some patients are better suited to PRK, CONTOURA^®, or a lens-based procedure, and Dr. Faktorovich or Dr. Parra will walk you through the alternatives if WaveLight Plus isn't the right match.

Why Choose Pacific Vision Institute for Ray-Tracing LASIK in San Francisco?

Dr. Ella Faktorovich founded Pacific Vision Institute more than two decades ago and has repeatedly been the first refractive surgeon in San Francisco to bring a new LASIK technology to patients, from wavefront-guided LASIK to CONTOURA^® Vision topography-guided treatment. That same first-adopter approach extends to WaveLight Plus ray-tracing LASIK. Dr. Faktorovich has been named a Castle Connolly Top Doctor for 20 consecutive years and is listed among the Top 100 Health Professionals in the World.

Dr. Andres Parra, is a renowned refractive, lens, and cataract surgeon leading the advanced vision correction surgical division at Pacific Vision Institute. Dr. Parra has performed thousands of vision correction surgeries, and his patients come from all walks of life, including professional athletes, artists, photographers, entrepreneurs, professors, fellow physicians and nurses, and patients traveling from abroad. Together, they personally examine every patient considering LASIK in San Francisco to match the right technology to the right eyes.

Consultation and Cost

Your first visit includes a full eye health evaluation and a Sightmap scan to confirm candidacy. Pricing for WaveLight Plus LASIK in San Francisco depends on your prescription, the complexity of your treatment plan, and whether both eyes are being treated. Our patient coordinators provide an itemized cost breakdown and financing options during your consultation.

The Treatment Experience

On surgery day, the Sightmap captures the diagnostic data used to build your Digital Eye Twin, and the ray-tracing software calculates your personalized ablation profile. The EX500 excimer laser then applies that profile to reshape the cornea. The procedure itself is typically completed in a matter of minutes per eye.

Recovery and Results Timeline

Most patients notice significant improvement in vision within a day of surgery, with continued stabilization over the following weeks. As with any LASIK procedure, mild dryness or light sensitivity in the first few days is common and typically resolves as the eye heals.

Am I a Candidate If I've Already Had LASIK or PRK?

Some previous refractive surgery patients may still be candidates. Dr. Faktorovich or Dr. Parra will evaluate your corneal thickness and prior surgical history to confirm.

WaveLight Plus vs. Topography-Guided and Wavefront-Optimized LASIK

Pacific Vision Institute already offers CONTOURA^® Vision topography-guided LASIK, and patients often ask how it compares to WaveLight Plus ray-tracing LASIK. Both use the EX500 excimer laser, but the two platforms plan treatment differently:

CONTOURA^® (topography-guided): Maps the corneal surface using Placido-ring topography, sampling thousands of elevation points on the cornea's surface.
WaveLight Plus (ray-tracing-guided): Builds a full 3D optical model of the eye from wavefront, biometry, and tomography data, then calculates the ablation profile through computerized ray tracing.
Wavefront-optimized LASIK: Uses a standardized correction based on the eye's overall refractive error and average corneal shape, without a custom 3D eye model.

During your consultation, Dr. Faktorovich or Dr. Parra will review your corneal maps and Sightmap results to recommend which platform best fits your eyes.

WaveLight Plus FAQs

Is WaveLight Plus LASIK safe?

Yes. WaveLight Plus uses the same FDA-cleared EX500 excimer laser platform used in PVI's existing LASIK programs, with ray-tracing software adding a more personalized diagnostic layer to treatment planning.

How is WaveLight Plus different from standard LASIK?

Standard wavefront-optimized LASIK uses generalized corneal shape data. WaveLight Plus instead builds a 3D model from over 100,000 individual data points on your eye and calculates your ablation profile from that model.

Will I still need a manifest refraction test?

Because the Sightmap and ray-tracing software gather objective measurements directly, treatment planning does not depend on manifest refraction input, which can shorten the planning process.

What are the risks of ray-tracing LASIK?

Risks are similar to those of other forms of LASIK and can include temporary dry eye, glare, halos, or under/overcorrection. Your surgeon will review your individual risk profile during your consultation.
