Epioxa epi-on cross-linking for keratoconus
Reviewed by Rajesh Khanna, MD
Epioxa strengthens the cornea without removing its outer surface layer. At Khanna Vision Institute it is offered with insurance approval only.
What is Epioxa, and why does it matter?
Epioxa is a corneal cross-linking treatment for keratoconus that does not require removing the cornea's outer surface layer (the epithelium). It uses oxygen-enriched topical riboflavin solutions activated by UV-A light to strengthen corneal collagen and slow disease progression. Because the epithelium stays intact, recovery is generally less painful and faster than traditional epithelium-off cross-linking. Epioxa was approved by the FDA in October 2025 and is now available in clinical practice. At Khanna Vision Institute in Beverly Hills, Dr. Khanna offers Epioxa as one of the full range of keratoconus treatments — CTAK remains available for vision restoration in advanced cases. Cross-linking is offered as Epioxa (epi-on), insurance approval only. Epi-off is not a standard option; it may be considered only as a conditional exception if Glaukos approves it in select cases.
Why this matters
A new keratoconus option for active Angelenos
Keratoconus can disrupt work, screens, driving, sports, contact lenses, and confidence. For working professionals, performers, and students in Los Angeles, time off for recovery from a traditional cross-linking procedure can feel impossible. Epioxa is designed to help close that gap — same therapeutic goal, gentler recovery profile.
FDA approval gives families confidence
Epioxa has been formally reviewed and approved by the FDA as a treatment for keratoconus, giving patients an established option that does not depend on removing the epithelium.
Less recovery downtime
Because the surface layer of the cornea is preserved, most patients experience less surface-healing discomfort and a faster return to screens, work, and driving compared with epi-off treatment.
Earlier action protects future options
Cross-linking helps stop progression — it doesn't reverse damage. Acting earlier preserves the cornea before irregularities advance, keeping more long-term treatment options open.
Epi-on vs. epi-off
What sets Epioxa apart
Traditional epi-off corneal cross-linking requires removing the corneal epithelium so that riboflavin can penetrate the cornea. Epioxa is engineered to work with the epithelium left in place — combining specialized riboflavin formulations, oxygen enrichment, and UV-A activation to drive the cross-linking reaction without needing to remove the surface layer.
Why Beverly Hills patients ask about epi-on
For working professionals, performers, students, and active families, surface-layer healing time is a real consideration. Keeping the epithelium intact may shorten time away from screens, contacts, work, and travel. Candidacy is determined by a complete corneal exam.
Traditional epi-off
- Epithelium is removed before treatment
- Surface healing typically takes several days
- Remains the right option for some clinical situations
Epioxa epi-on
Experience matters
- No removal of the epithelium
- Designed for improved comfort and faster recovery
- Uses oxygen enrichment and UV-A activation
Why patients choose Dr. Khanna for Epioxa
Epioxa is a new procedure. Dr. Khanna is not. He brings 25+ years of corneal and refractive expertise to every Epioxa case, informed by his fellowship at the University of Cincinnati and over 25,000 procedures performed across his career.
When a procedure is genuinely new, the surgeon's depth in the surrounding specialty is what matters most. Cornea is Dr. Khanna's life's work — and he has performed corneal procedures on his own family members, including his mother and his wife. That speaks to his confidence in the standard of care he delivers.

Treatment overview
Drops, oxygen, light — a streamlined epi-on process
Every treatment plan is individualized after corneal mapping, pachymetry, refraction, eye health evaluation, and a discussion of risks and alternatives. Treatment occurs at our Beverly Hills office on Wilshire Boulevard.
Step 1 · Riboflavin drops
A specialized riboflavin solution is applied directly to the eye. The epithelium remains in place — no scraping required.
Step 2 · Oxygen enrichment
Supplemental oxygen drives the cross-linking chemistry — a key innovation that makes epi-on treatment possible.
Step 3 · UV-A activation
Ultraviolet-A light activates the riboflavin, triggering the cross-linking reaction that strengthens the corneal collagen.
Insurance & cost support
A medical consultation is required
Reported Epioxa side effects include red eye, haze, light sensitivity, disruption of corneal surface cells, eye pain, eye irritation, watery eyes, eyelid swelling, fine white lines in the cornea, reduced sharpness of vision, dry eye, and eye inflammation.
Epioxa may not be appropriate for patients with certain allergies, certain post-cataract surgery lens situations, a history of herpetic keratitis, pregnancy, or other eye health concerns. Your Khanna Vision Institute evaluation will review risks, benefits, alternatives, and realistic expectations.
FAQ
Common questions from Beverly Hills patients
Yes. Khanna Vision Institute offers Epioxa epi-on corneal cross-linking at our Beverly Hills location at 9100 Wilshire Boulevard, Suite 265E. Dr. Khanna is among the early Southern California adopters of this FDA-approved treatment.
The treatment, equipment, and standard of care are identical. The Beverly Hills office serves patients from Los Angeles, Santa Monica, West Hollywood, Brentwood, Bel Air, Hollywood, Century City, and Mid-City.

Yes. The 9100 Wilshire Boulevard building offers valet and self-park options. For international and out-of-state patients, our team helps coordinate scheduling, ground transportation, and lodging recommendations near the office.
Dr. Khanna is fellowship-trained in corneal and refractive surgery (University of Cincinnati), with 25+ years of clinical experience and over 25,000 eye procedures performed. He has been a Southern California Super Doctor for six consecutive years. While Epioxa is a new procedure, the surgeon's overall corneal expertise is what matters most — and Dr. Khanna brings that depth to every case.
It depends on the patient. The major advantage of epi-on is keeping the epithelium intact, which may improve comfort and recovery. Cross-linking is offered as Epioxa (epi-on), insurance approval only. Epi-off is not a standard option; it may be considered only as a conditional exception if Glaukos approves it in select cases. Epioxa is the cross-linking treatment, and it is insurance-approval only. The right choice still depends on corneal thickness, severity, age, health history, insurance, and physician judgment.
No. The goal of cross-linking is to stabilize the cornea and reduce the risk of worsening keratoconus. Vision correction may still require glasses, specialty contacts, scleral lenses, or — in advanced cases — vision-restoring procedures like CTAK.
Not every patient is right for Epioxa. If it isn't appropriate, Dr. Khanna will explain why and walk you through alternatives, CTAK may be discussed for vision restoration. Cross-linking is offered as Epioxa (epi-on), insurance approval only. Epi-off is not a standard option; it may be considered only as a conditional exception if Glaukos approves it in select cases. KVI offers the full range of keratoconus treatments, so your evaluation isn't limited to one option.
