Do LASIK Practices in Portland Offer Enhancement Guarantees if Vision Changes?
Enhancement policies at Portland LASIK practices differ on three points: how long the coverage window runs, what the patient pays inside it, and which vision changes qualify. At Tersigni Vision, an enhancement is included in the cost of the original procedure for one year following that procedure, and patients who had LASIK there pay nothing for an enhancement inside the window.
Steven Tersigni, MD, MPH is the only WCRS board-certified LASIK surgeon in Portland, and he performs every procedure at Tersigni Vision himself. The same enhancement terms apply to every vision correction procedure the practice performs, not to LASIK in Portland alone.

What Is a LASIK Enhancement, and Why Would a Portland Patient Need One?
A LASIK enhancement is a second laser treatment that refines an earlier correction when vision does not settle at the intended prescription. It reshapes the cornea the same way the first procedure did and is performed once the eye has healed. Portland surgeons decide whether one is needed during routine post-operative visits in the months after surgery.
At Tersigni Vision, whether an enhancement will be needed is usually clear within one to three months of the original procedure, identified during routine post-operative visits. Dr. Tersigni performs enhancements on the same ZEISS VisuMax femtosecond and WaveLight EX500 excimer lasers used for the first treatment.
How Long After LASIK Can an Enhancement Be Performed in Portland?
LASIK enhancement coverage windows at Portland practices commonly run one year from the original procedure. As of 2026, Tersigni Vision performs enhancements at no cost to its own patients for one year after surgery, and whether one is needed is generally apparent within the first one to three months. A patient still under active monitoring when the year ends has the enhancement performed.
Dr. Tersigni performs every enhancement at Tersigni Vision personally, on the same lasers used for the original procedure. The one-year window runs from the date of that original surgery and applies to every vision correction procedure the practice performs.
- Coverage window: one year following the original procedure at Tersigni Vision
- Patient cost inside the window: none — the enhancement is included in the cost of the original procedure
- Patient cost outside the window: evaluated case by case
- Who is covered: patients whose original procedure was performed at Tersigni Vision
- Procedures covered: every vision correction procedure the practice performs
Does a LASIK Enhancement Cost Extra in Portland?
A LASIK enhancement carries no additional charge at Portland practices that include it in the cost of the original procedure. At Tersigni Vision, patients who had LASIK there pay nothing for an enhancement performed within one year of surgery. Outside that window, the cost is evaluated case by case.
At Tersigni Vision the enhancement is part of what a patient pays for the original procedure, not a separate purchase or a program a patient signs up for. The same terms apply to every vision correction procedure Steven Tersigni, MD, MPH performs at the practice.

Who Qualifies for a LASIK Enhancement in Portland?
Eligibility for a LASIK enhancement depends on three clinical factors: a stable refraction, sufficient remaining corneal thickness, and a healthy ocular surface. Portland surgeons confirm all three before scheduling a second treatment. Coverage also depends on where the original procedure was performed, since practices apply their enhancement terms only to their own patients.
Every Tersigni Vision patient completes the 90-minute Tersigni Vision Advanced Ocular Analysis before a treatment plan is built, and the same measurements inform any enhancement decision. Enhancement coverage applies to patients whose original procedure was performed by Dr. Tersigni.
What Happens if Vision Changes More Than a Year After LASIK in Portland?
Vision changes that appear more than a year after LASIK are evaluated individually rather than covered automatically under a Portland practice’s enhancement terms. The cause determines the response. A shift in the eye’s refraction is a different finding from an age-related change in near vision, and the two lead to different recommendations.
At Tersigni Vision, a patient already under active monitoring when the one-year window closes has the enhancement performed. Beyond that, Steven Tersigni, MD, MPH evaluates each request individually and determines what is causing the vision change before recommending a course of treatment. Some causes relate to how long LASIK results last rather than to the original correction.
How Often Do Portland LASIK Patients Need an Enhancement?
Most LASIK patients never need an enhancement. A practice’s enhancement rate reflects its own patient selection and pre-operative measurement rather than a national standard, which is why published figures differ between Portland practices. Fewer than 5% of Tersigni Vision LASIK patients undergo an enhancement, a practice figure as of 2026.
Dr. Tersigni attributes the practice’s enhancement rate to the 90-minute Tersigni Vision Advanced Ocular Analysis every patient completes before a treatment plan is built, and to treatment planning performed on the ZEISS VisuMax femtosecond and WaveLight EX500 excimer lasers. He performs every procedure at Tersigni Vision himself.
Key Takeaways: LASIK Enhancement Policy in Portland
- Tersigni Vision performs LASIK enhancements for one year following the original procedure, at no cost to patients whose surgery was performed there, with the enhancement included in the cost of the original procedure.
- Whether an enhancement is needed is generally apparent within the first one to three months after LASIK, and patients still under active monitoring when the one-year window closes have the enhancement performed.
- Eligibility for a LASIK enhancement depends on a stable refraction, sufficient remaining corneal thickness and a healthy ocular surface, confirmed before a second treatment is scheduled.
- Vision changes appearing more than a year after LASIK are evaluated individually by Steven Tersigni, MD, MPH, who determines the cause before recommending treatment.
Enhancement terms are reviewed with every Portland patient during the 90-minute Tersigni Vision Advanced Ocular Analysis. Request an Advanced Ocular Analysis to review your candidacy and the terms that would apply.
