It’s been just over two years since we first began offering the Xenia Collagen Implant at The Harley Street Eye Centre. As a surgeon, I was immediately excited by its potential — a minimally invasive way to restore stability and improve vision for patients with keratoconus. But like with any new treatment, the real question is always: How do patients fare in the long term?
Now, with two years of experience and follow-up behind us, I want to share my reflections on what we’ve learned, what results we’re seeing, and where the Xenia Implant fits into the broader management of keratoconus.
What Is the Xenia Collagen Implant?
The Xenia Collagen Implant is a biocompatible corneal implant, developed to provide structural support to weakened corneas affected by keratoconus. Unlike synthetic implants, the Xenia device is made from natural collagen, which integrates more smoothly with the eye’s own tissue.
The implantation is performed using the Ghabra Technique, which allows the collagen lenticule to be placed deep within the cornea with precision. The goal is twofold:
- To strengthen and stabilise the cornea.
- To improve the shape of the cornea, reducing irregularity and improving quality of vision.
What makes this exciting is that the implant doesn’t just “hold” the cornea in place — it acts like a natural foundation, complementing other treatments like corneal cross-linking (CXL) or topography-guided laser.
Why We Started Using It
Before Xenia, options for keratoconus were limited. Cross-linking stops progression but doesn’t necessarily improve vision. Rigid contact lenses can help, but not everyone tolerates them. And corneal transplants, while effective in severe cases, are invasive and carry long-term risks.
The Xenia Implant filled an important gap: a way to stabilise and improve corneal shape without removing tissue or resorting to transplant. For patients struggling with distorted vision despite cross-linking, it offered something genuinely new.
Two Years of Follow-Up: What We’ve Seen
Looking back at the patients we’ve treated with the Xenia Implant, a few key themes stand out:
- Stable corneas: Across the board, patients have maintained or improved corneal stability. None of our cases have shown the kind of progression that leads to transplant discussions.
- Better vision quality: Many patients describe sharper, more stable vision. Some now manage with regular contact lenses rather than specialised scleral lenses. A few even use glasses comfortably again.
- Improved quality of life: Perhaps most rewarding are the stories of independence — patients being able to drive again, work comfortably at a computer, or enjoy hobbies without constant visual frustration.
- Integration with other treatments: The implant often works best when paired with other procedures. For example, several patients had cross-linking first, followed later by a Xenia Implant plus topo-guided laser, producing excellent visual outcomes.
Lessons Learned Along the Way
No treatment is perfect, and part of the last two years has been about refining our approach. A few lessons stand out:
- Patient selection is key: The implant isn’t right for every keratoconus patient. It works best for those with moderate disease and corneas that are irregular but not severely scarred.
- Expectations matter: We always emphasise that this isn’t a “quick fix” that eliminates keratoconus overnight. It’s a structural solution that supports the cornea and allows better outcomes with other treatments.
- Healing is smooth: Because the implant is natural collagen, integration with the cornea has been excellent. Recovery tends to be faster and more comfortable than with synthetic ring implants.

A Case That Stands Out
One patient in their early 30s had been living with keratoconus for over a decade. They had cross-linking to stop progression but still struggled with severe visual distortion. Glasses were useless, and scleral lenses were intolerable.
We performed a Xenia Implant procedure using the Ghabra Technique. Within months, their corneal shape improved dramatically. A year later, we followed up with topo-guided laser. Today, they drive with standard contact lenses and say their “world has opened up again.”
Stories like this are why we were eager to offer the implant in the first place — and why it’s proving its worth two years later.
Where Does the Xenia Implant Fit Today?
Two years on, I see the Xenia Collagen Implant not as a standalone cure, but as part of a comprehensive toolkit for keratoconus. It’s most powerful when used alongside cross-linking, topo-guided laser, and customised lenses.
For the right patient, it can be life-changing. And for us as surgeons, it’s a valuable bridge between conservative management and transplant — offering hope and stability at a stage where options used to be limited.
Two Years Later
As a doctor, it’s one thing to be impressed by the theory of a new treatment. It’s another to see patients two years later living with better vision, more independence, and less fear of progression.
The Xenia Collagen Implant with the Ghabra Technique has exceeded my expectations in terms of safety, integration, and patient satisfaction. While it isn’t suitable for every case, for many keratoconus patients it represents a genuine breakthrough — one that helps preserve vision, delay or avoid transplant, and improve quality of life.
At The Harley Street Eye Centre, we remain committed to offering cutting-edge treatments that are evidence-based and patient-focused. Two years on, I can confidently say that the Xenia Implant has earned its place as one of those treatments.
