A UK Pioneer in Advanced Keratoconus Treatment — Based in Essex
Most patients with keratoconus are told to wear rigid contact lenses and wait. The reality is that advanced surgical treatments now exist that can stabilise the cornea, improve unaided vision, and significantly reduce — or in some cases eliminate — the need for lenses altogether.
Mr Hatch Mukherjee is one of the first surgeons in the UK to perform both CAIRS and topography-guided laser surgery for keratoconus — bringing techniques previously available only in specialist centres to patients across Essex and East Anglia.

Struggling with contact lenses for keratoconus?
The latest techniques could change that.
Most patients are told to persevere with lenses and come back if things get worse. But advanced surgical treatments now exist that most eye clinics simply cannot offer. Find out if they could work for you.
“My lenses are getting harder to wear. I can barely get through a full day.”
Topography-guided laser and CAIRS can reduce corneal irregularity — making lens wear more comfortable, or removing the need for them altogether.
“Even with my lenses in, my vision still isn’t right.”
Corneal reshaping with topography-guided laser targets the distortion at source — improving both unaided and corrected vision in ways lenses cannot.
“I’ve been told I might need a corneal transplant.”
CAIRS and topography-guided laser can reshape the cornea without transplant surgery in many cases — but the sooner you’re assessed, the more options remain open.
“My prescription keeps changing — my optician says things are getting worse.”
A shifting prescription means active progression. Cross-linking can stabilise the cornea now — and once stable, further treatment can meaningfully improve your vision.
“I was told to get lenses and come back in a year. But I’m struggling now.”
Lenses manage symptoms — they don’t treat the condition. A specialist assessment may reveal surgical options most general eye clinics simply cannot offer.
“I’ve had cross-linking but I’m still completely dependent on lenses.”
Cross-linking halts progression — it doesn’t reshape the cornea. CAIRS and topography-guided laser can do both, and are available after cross-linking.

The Vision Surgeon Advantage
Revolutionary treatments now available for keratoconus.
More than contact lenses. More than cross-linking. Advanced surgical options now exist to stabilise the cornea, reshape it, and significantly reduce — or in some cases eliminate — dependency on lenses. The right treatment, from a specialist with the full range of options.
What is keratoconus?
The cornea — the clear front surface of the eye — normally holds a neat, dome-like shape. In keratoconus, it progressively thins and bulges forward into a cone. This distorts how light enters the eye and makes sharp focus increasingly difficult. Glasses help initially. Contact lenses can compensate for longer. But as the cone advances, even well-fitted lenses become harder to tolerate and vision may continue to deteriorate.
Why specialist assessment changes everything
- ✓Blurred or distorted vision not fully corrected by glasses
- ✓Halos and glare around lights, especially at night
- ✓Frequent prescription changes — glasses no longer keeping up
- ✓Rigid contact lenses becoming painful or impossible to wear
- ✓Increased sensitivity to light
- ✓Difficulty driving at night
- ✓Optician says the cornea is thinning or changing shape
What we offer that most clinics cannot
Most keratoconus patients are offered two things: rigid contact lenses to manage their vision, and cross-linking if the condition is progressing. Mr Mukherjee offers a broader range of advanced surgical treatments — including pioneering techniques that can reshape the cornea and meaningfully reduce lens dependence.
Corneal Cross-Linking (CXL)
The proven treatment to stop keratoconus advancing. Riboflavin drops are applied to the cornea and activated with UV light, strengthening the collagen structure and preventing further thinning. Cross-linking is the essential first step for progressive keratoconus — it protects everything that follows.
Performed as a day-case procedure, it is most effective when the cornea is still of adequate thickness. Mr Mukherjee has been performing CXL for many years and has contributed to the published literature in this area.
Topography-Guided Laser Surgery
Once the cornea is stable, topography-guided laser treatment uses a detailed map of your corneal surface to selectively smooth the irregular areas that cause distorted vision. By reducing irregular astigmatism, it can significantly improve unaided vision and reduce dependence on contact lenses.
Mr Mukherjee is one of the first surgeons in the UK to have trained in and to offer this technique specifically for keratoconus patients — an advanced application of laser surgery that requires both refractive and corneal expertise to perform safely.
CAIRS
Corneal Allogenic Intrastromal Ring Segments use donor corneal tissue — rather than synthetic plastic rings — implanted within the cornea to reshape it and reduce the irregular astigmatism that keratoconus causes. Because donor tissue is biologically compatible, it integrates naturally and achieves a more regular corneal surface.
CAIRS can both halt progression and meaningfully improve unaided and corrected vision, often reducing or eliminating the need for contact lenses. Mr Mukherjee is a UK pioneer in this procedure.
Contact Lens Management
Specialist contact lenses remain a valuable option for managing vision in keratoconus, particularly in earlier stages or during the period between surgery and full stabilisation.
Mr Mukherjee works with specialist contact lens practitioners across Essex and East Anglia. For patients who are suitable surgical candidates, contact lenses are a bridge — not a destination.

The Vision Surgeon Advantage for keratoconus patients
Most keratoconus patients are seen in general eye clinics where the treatment options end at cross-linking and contact lenses. Mr Mukherjee offers two techniques that go further — and that bring him to a very small group of surgeons in the UK who can provide them.
CAIRS uses donor corneal tissue to reshape the cornea from within — integrating naturally, halting progression, and improving corneal regularity to reduce lens dependence. Topography-guided laser uses a precise map of your corneal surface to smooth the irregular areas that cause distortion — reducing the irregular astigmatism that makes contact lens wear so challenging. Together, these techniques create a genuine pathway towards reduced or eliminated lens dependence for many patients with keratoconus.
Why choose Mr Hatch Mukherjee for keratoconus?
Most keratoconus patients see an ophthalmologist who can perform cross-linking. Far fewer see a specialist who can also offer CAIRS and topography-guided laser — and fewer still can combine all three with the refractive planning needed to target a genuine reduction in lens dependence. That combination is what makes the difference between managing keratoconus and treating it.

What to expect
Specialist assessment
Detailed corneal topography and pachymetry (thickness mapping) with Mr Mukherjee. A clear picture of where your keratoconus stands — mild, progressive or advanced — and which treatments are appropriate.
Treatment planning
A personalised discussion of every option available — cross-linking, topography-guided laser, CAIRS, or a staged combination. The goal is not just to stabilise the cornea but to set the best possible visual outcome, which may include meaningful reduction in lens dependence. Mr Mukherjee will explain the reasoning and realistic expectations clearly.
Treatment
Both cross-linking and CAIRS are day-case procedures performed under local anaesthetic. Cross-linking takes approximately 60 minutes per eye. CAIRS is performed under topical anaesthesia with a short recovery period.
Follow-up & monitoring
Keratoconus requires ongoing monitoring. Mr Mukherjee provides structured follow-up with repeat corneal mapping to confirm stability and assess whether any further intervention would be beneficial.
Frequently Asked Questions
RELATED TREATMENTS
Not sure laser is right for you?
If laser eye surgery is not suitable — due to a high prescription, thin corneas or other factors — there are excellent alternatives that Mr Mukherjee can discuss at consultation.
Laser Eye Surgery
Once keratoconus is stabilised, selected patients may be candidates for topography-guided laser correction to reduce residual refractive error.
Lens Replacement Surgery
For patients with keratoconus and presbyopia, lens replacement with a premium IOL can address both conditions simultaneously.
Cataract Surgery
Keratoconus patients developing cataracts require particularly careful biometry and lens selection — an area of specialist expertise for Mr Mukherjee.
Advanced keratoconus treatment — not just contact lenses.
A consultation with Mr Mukherjee gives you detailed corneal mapping, an honest assessment of where your keratoconus stands, and a clear conversation about what is achievable — including whether advanced laser or corneal surgery could reduce your dependence on lenses.
